    @ArduiSens RS485 should be already there in the development version (https://github.com/mysensors/NodeManager/tree/development). Nothing special, I've just added to config.h some sample directives, commented out by default. Let me know in case this approach can be improved. Thanks!

  • @user2684, found the RS485 settings (thanks), but having problems with disabling the BATTERY_MANAGER option.
    We don't need this option in a RS485 serial wired network (or RS485 serial gateway).

    #define BATTERY_MANAGER 0

    gives following compiling errors:
    sketch\NodeManager.cpp: In member function 'void NodeManager::process(Request&)':

    @ArduiSens thanks, good catch, this looks like a mistake on my side, keep on eye on https://github.com/mysensors/NodeManager/issues/206 for a fix which should come shortly.

  • @user2684, why does NodeManager take so many sketch memory?
    (#define BATTERY_MANAGER 1; #define DEBUG 1; #define MODULE_DS18B20 1)
    sketch NodeManager RS485 config for DS18B20 --> 28730 bytes (93%) of program storage space. Maximum is 30720 bytes.

    own sketch for RS485 SR04T --> 17078 bytes (55%) of program storage space. Maximum is 30720 bytes.

    OK, DS18B20 and SR04T are not the same but DS18B20 is less complex, so 38% more memory is pretty much.
    Do I miss something?

  • @ArduiSens for curiosity, what board are those numbers from?

    NodeManager is a young project. You can expect changes and optimizations in the future. And also you can do suggestions and pull requests.

  • @Sergio, I know and it's OK. I'm just playing (trying to convert my RS485 projects).
    In the cases above I'm using Nano boards.

  • Contest Winner

    @ArduiSens that's true, many optimizations can be done to save additional storage. With v1.5.1 a design issue eating up 20% of the storage has been fixed but many things for sure can be improved. As for the current version, try lowering down MAX_SENSORS (which by default allocates the pointers for 10 child IDs) and set DEBUG to 0 after your tests. The latter especially should give you another 20% of storage back (static strings of the debug output are consuming most of this storage). Thanks

  • How to add i2c sensor?
    I see that there is a git issue asking about si7021 which I would also like to use as well, but has someone perhaps connected it already by creating a custom sensor?
    How difficult would it be?

  • Contest Winner

    Hi @dakipro, I've just commented on github for the Si7021. Regarding the custom sensor, have a look at this https://github.com/mysensors/NodeManager#creating-a-custom-sensor (or the same section on the development branch documentation if you are using it). As far as you create an (inline) class inheriting from Sensor or its subclasses and implement the methods listed in the documentation you can invoke registerSensor() providing the instance of your class and NodeManager will take care of it. Just take inspiration from an existing sensor if you want to do so, it should save you some time. Thanks

    Hello All,

    NodeManager v1.6 is finally available! Download and upgrade instructions can be found as always on https://github.com/mysensors/NodeManager

    First of all I want to thank everybody contributing to the project, especially those who have submitted pull requests to the repository.

    In v1.6 we have 36 out-of-the-box sensors as well as a good number fixes and enhancements. The most notable are for sure the capability to customize any sensor remotely through a brand new remote API and a more flexible and effective way to configure reporting intervals and sleep cycles:

    • Introduced new remote API to allow calling almost ALL NodeManager's and its sensors' functions remotely
    • Reporting interval configuration is now indipendent from the sleep cycle
    • Reporting interval can be customized per-sensor
    • All intervals (measure/battery reports) are now time-based
    • Added support for BMP280 temperature and pressure sensor
    • Added support for RS485 serial transport
    • Added support for TSL2561 light sensor
    • Added support for DHT21 temperature/humidity sensor
    • Added support for AM2320 temperature/humidity sensor
    • Added support for PT100 high temperature sensor
    • Added support for MH-Z19 CO2 sensor
    • Added support for analog rain and soil moisture sensors
    • Added support for generic dimmer sensor (PWM output)
    • Added support for power and water meter pulse sensors
    • Radio signal level (RSSI) is now reported automatically like the battery level
    • SensorRainGauge now supports sleep mode
    • SensorSwitch now supports awake mode
    • SensorLatchingRealy now handles automatically both on and off commands
    • SensorMQ now depends on its own module
    • Added safeguard (automatic off) to SensorDigitalOutput
    • Any sensor can now access all NodeManager's functions
    • DHT sensor now using MySensors' DHT library

    For those who have previously forked the repository, please ensure to merge the updated development branch first before submitting any new PR.

  • Hi, obviously a lot of work gone into NodeManager thanks, I'm quite new to MySensors but have started working on.a few sensors around my home.

    I was just looking through the code (NodeManager.cpp) and an apparent issue jumped out at me (I write C++ for a living on very large boxes but still worry about performance!)
    The two functions NodeManager::_saveConfig and NodeManager::_loadConfig are used to save the _sleep_time value to EEPROM. The code splits the long value into 3 parts by dividing by successively 255 . On loading the value is reconstructed by multiplying by 255.
    I'm pretty sure that you meant to use 256 to split the long value into three independent bytes to store.
    Dividing or multiplying by 255 is potentially expensive whereas dividing or multiplying by 256 is much faster simply requiring shifts.
    The normal code for splitting a long value into individual bytes would be something like
    uint8_t byte0 = _sleep_time & 0xff; // compiler should generate a simple byte load
    uint8_t byte1 = (_sleep_time >> 8 ) & 0xff; // compiler should still generate a simple byte load from the second byte of _sleep_time
    uint8_t byte2 = (_sleep_time >> 16) & 0xff; // as before should still be a byte load.
    I'm not sure how good the gcc optimiser is for the AVR code but, putting the shift&mask operations directly into the calls of saveSave(...) may avoid having to allocate local variables as in
    // save the 3 bits
    saveState(EEPROM_SLEEP_1,_sleep_time & 0xff);
    saveState(EEPROM_SLEEP_2,(_sleep_time >> 8 ) & 0xff);
    saveState(EEPROM_SLEEP_3, (_sleep_time >> 16) & 0xff);

    I am not an expert in in the AVR architecture or instruction set so maybe there is a good reason why you are using 255 instead of 256 - it just seems strange!



  • Hi,
    I have started to play with nodemanager and I have registered a SENSOR_DS18B20. Nodemanager handles all the heavy lifting and the sensor is reporting the temperature 100%. I can change the sleep and report intervals with “setReportIntervalSeconds and setSleepSeconds”.

    Question 1:
    According to the MySensors documentation (https://www.mysensors.org/download/serial_api_20#variable-types) a S_TEMP sensor can report the V_TEMP value and a V_ID value. Nodemanager populates the V_TEMP variable, but how can I populate and send the V_ID value?
    If I want to add an additional sensor I must register it with “registerSensor” and I would set the report interval for this sensor by getting a pointer to this sensor with “getSensor”, but how do I add custom code for this sensor in Loop()? How do I ensure that the custom code is only executed for this sensor and not for the other sensor?

  • @user2684, Will you like to consider adding a #DEFINE to let user configure PowerOn function to select "GND-On" or "Vcc-On" (5V0)?

    With this GND-On PowerOn, a single GND wire controlled by a digital pin can control the power instead of 2 wire poweron control. [so many control words :)]

    For devices that require more than ~10mA current (~Arduino pin current) this GND-On configuration can help externally supplied higher powered V+ current to switch the devices! Thus, will also help 3V3 devices to be controlled by PowerOn, of course, with external 3V3!

  • I just started using NodeManager, mainly for the ability to send settings to the node.
    I started with a plain analog (Voltage) sensor, and it works just fine. But I cannot make a DS18B20 sensor to send any temperature data. It registers on the gateway, and that's it.
    I have enabled the DS18B20 module in the config.h.
    This is the code in the sketch:

       * Register below your sensors
      int temp = nodeManager.registerSensor(SENSOR_DS18B20);
       * Register above your sensors

    Am I missing something?

  • Contest Winner

    @graham86 there was no special reason why I used 255 apart from my lack of c++ knowledge 😛 Thanks for the hit, I'll fix it with https://github.com/mysensors/NodeManager/issues/215

  • Contest Winner

    Hi @FredRoot, V_ID has not been used so far by NodeManager, thanks for noticing it! I've added https://github.com/mysensors/NodeManager/issues/216 for this

    Regarding the other question you have two ways: 1) add your custom code to onLoop() in NodeManager.cpp (this will not survive to an upgrade) 2) create a custom sensor inheriting from Sensor or other subclasses and call registerSensor() by providing an instance of this class (https://github.com/mysensors/NodeManager#creating-a-custom-sensor)

  • Contest Winner

    @vikasjee sorry my bad, I think I couldn't understand your suggestion 🙂 Do you have an example to let me understand better? thanks and sorry again, I'm sure I'm missing something somewhere 🙂

  • Contest Winner

    @kted I think you forgot the pin to which the sensor is attached to. e.g.


  • @user2684 Actually, you are right. Thank you.
    But shouldn't the compiler throw an error?

    Now to the hard part: How to send the actual command from Domoticz, for example to change the sleep duration...

  • @kted Such functionality it's supposed to be hard-coded in the node sketch. But if you want to make it modificable from Domoticz, perhaps you can make use of the V_VAR1-3 variables and modify them in domoticz, receive them in the node and pass to NodeManager.

  • Contest Winner

    @kted the compiler doesn't complain because for some sensors (e.g. those using i2c), the pin is not required so I made it not mandatory. As for Domoticz, I'll let others to address your question since I don't know that controller enough. Thanks

  • @user2684 I have looked at the changes in https://github.com/mysensors/NodeManager/pull/174 which incorporates an alternative improved implementation for the _LoadConfig/_SaveConfig functions (interesting that using an intermediate union requires less code than my shifting version- presumably due to differences in the way the GCC optimiser works for an AVR target).
    I spotted a coupld of minor points and was also able to further reduce the code size.
    Firstly as we are writing C++ rather than C the declaration of the union should just be
    // Local union used to split _sleep_time into bytes
    union tLongByteArrayCombo{
    long long_value;
    uint8_t byte_array[4];
    } ;
    (The typedef systax, although valid C++ is unnecessary - a simple union declaration is sufficient.)
    There is also a typo - the original had a member called byte_arrray instead of byte_array.

    You can also save 24 bytes of code by avoiding the use of a local union variable and simply aliasing _sleep_time as the union type. So instead of _load_config doing -
    tLongByteArrayCombo c;
    c.byte_array[0] = loadState(EEPROM_SLEEP_1);
    c.byte_array[1] = loadState(EEPROM_SLEEP_2);
    c.byte_array[2] = loadState(EEPROM_SLEEP_3);
    c.byte_array[3] = 0;
    _sleep_time = c.long_value;
    You can do
    (((tLongByteArrayCombo&)_sleep_time).byte_array )[0] = loadState(EEPROM_SLEEP_1);
    (((tLongByteArrayCombo&)_sleep_time).byte_array )[1] = loadState(EEPROM_SLEEP_2);
    (((tLongByteArrayCombo&)_sleep_time).byte_array )[2] = loadState(EEPROM_SLEEP_3);
    (((tLongByteArrayCombo&)_sleep_time).byte_array )[3] = 0;
    And in _save_config instead of
    tLongByteArrayCombo c;
    c.long_value = _sleep_time;
    saveState(EEPROM_SLEEP_1, c.byte_array[0]);
    saveState(EEPROM_SLEEP_2, c.byte_array[1]);
    saveState(EEPROM_SLEEP_3, c.byte_array[2]);
    you can use
    saveState(EEPROM_SLEEP_1, (((tLongByteArrayCombo&)_sleep_time).byte_array )[0] );
    saveState(EEPROM_SLEEP_2, (((tLongByteArrayCombo&)_sleep_time).byte_array )[1] );
    saveState(EEPROM_SLEEP_3, (((tLongByteArrayCombo&)_sleep_time).byte_array )[2] );

    In my specific sample sketch I had the following code sizes

    Original NodeManager.cpp 28242 Bytes
    NodeManager with patch from pull rq 174 - 28154 Bytes (saving of 88 Bytes of code(
    Patched NodeManager with additional changes above - 28130 Bytes ( saving another 24 Bytes of code)

    user2684 created this issue in mysensors/NodeManager

    closed Fixed compiler warnings #174

  • Contest Winner

    @graham86 I guess you are referring to https://github.com/mysensors/NodeManager/pull/217, not 174, am I wrong? Anyway, any contribution that would help saving bytes is more than welcome: NodeManager is becoming more and more complex and the situations where we are out of storage start increasing so we definitely need to save whatever wherever we can 🙂 Regarding what you are proposing above, keep on eye on PR #217; once a new one dedicated to this part of the code will be created as discussed there, feel free to add your own PR to that branch or just let me know and I'll do it for you. Thanks!

  • @user2684, Sorry, couldn't revert to your query earlier as i was away building a small library.

    Expanding onto my earlier post on the requested Power Management feature -
    A simple switch will complete a circuit whenever its switched ON. This allows for placing the switch on the ground return wire too. So only a single GND-ON (Switched ON) will complete the circuit (without requiring an additional Vcc-ON switch).

    Now, with a developer configured #DEFINE GND_ON_POWER =1 may be checked in NodeManager's PowerManagement functions to DigitalWrite(Digital_GND_ON_Pin, LOW)
    for a switchON effect.

    Additionally, To provide an extra current to a sensor (i.e. more than a ~10mA-20mA, a max safe current provided by an Arduino pin) an external power source (other than Arduino +5V0 OR +3V3) may be provided by that external power source (of course with with a common ground wire between Arduino and that powersource to complete the circuit.)

    Also, with the current 2Wire PowerOn methodology, the VccPowerOn switch can provide only one positive voltage (that provided by Arduino Vcc, say +5V0) but not +3V3 (say) to the sensors. If some attached sensors require the other voltage (+3V3), then, this 2Wire PowerOn method will not help. Whereas, a single GND_On power methodology will still switch the circuit thus managing the Power to those sensors too.
    [PS: Signal Voltage Levels will still need to be managed by the developer attaching those sensors to the node]

    I think this simple feature will add on to the power of the PowerManagement functions.

    Hope this clears some air ? Open to suggestions...

  • Contest Winner

    @vikasjee thanks all clear now! I'll track this with https://github.com/mysensors/NodeManager/issues/224. Thanks again for the detailed explanation!

  • Contest Winner

    Hello all, just to let you know when compiling against the latest version of the mysensors 2.2.0-beta library, NodeManager will crash on startup, just after presenting the mysensors logo. Thanks @gohan for pointing this out! Root cause is still unknown but when MY_DEBUG is defined, the crash doesn't take place (https://github.com/mysensors/NodeManager/issues/223)

  • @user2684, Can we have a quick hot fix?

  • Contest Winner

    @vikasjee sure, as soon as I'll be able to understand the reason why it crashes when MY_DEBUG is not defined 😞 if somebody from the core team has any hit, would be really appreciated!

  • I'm afraid that issue 223 is not a NodeManager failure. I can reproduce it in a new sketch without using NodeManager.
    Other issue with MySensors are, NRF24 doesn't link with controller.
    If MY_DEBUG_VERBOSE_RF24 is defined, it automagically works.

  • @Sergio-Rius, with RF24_VERBOSE on, the system crashes in 40-50 seconds especially if you're connected to the serial monitor or if your serial gateway has this #DEFINE on.

  • Still more strange, suddenly started to work properly on 2/3 of my testing nodes. That killed me.

    What about the gateways you are using? And the controllers?

  • Hi,

    I'm having trouble with the motion sample code. I have changed the setSleepHours(1) command to setSleepMinutes(1). I understand that the sensor will send a hart beat every 1 min. This is working fine for the hart beat, but evertime the hart beat is send the sensor sends a Trigger messages as well even though the sensor is not triggered. I thought that maybe there is a power dip and that it might cause the PIR (RS501) to send a interrupt, but I have removed the setSleepMinutes command and replaced it with a setBatteryReportHours(1) command. This command is send correctly and the sensor only sends the trigger command when the PIR is triggered. Did anyone have a similar issue?

    Attached is the sensor debug output when the setSleepMinutes command is used:

    @FredRoot this is weird, from the logs looks like there is kind of a floating interrupt (alternatively 1 and 0). The strange thing is that the interrupt is coming from the call to mysensors' sleep() function which is returning a positive number corresponding to the interrupt linked to pin 3 instead of a negative value like it should after a sleeping cycle. Anybody else experiencing this behavior with NodeManager v1.6? thanks

  • @user2684 can you add support for the Si7021 sensor as found in sensebender micro?

    also, 2nd question.
    how do i register a sensor that is onboard?
    you ask for a child id and pin that it's on. but if it's an onboard sensor. how do you make that work? just omit the pin?

    @mvader for question #1, I've added it to the existing issue https://github.com/mysensors/NodeManager/issues/221. For question #2, for sensors using i2c the pin is not required despite within the code nodemanager will set a random pin (have a look at SensorSHT21 for example)

    After a few months working behind the scene, NodeManager got kind of a full review in terms of architecture and usability. The code should be now simpler to understand for new users, the memory utilization has been optimized and the overall user experience has been improved.

    The looooong list of things that have been changed are detailed on https://github.com/mysensors/NodeManager/pull/229.
    Please note this is only available in the development branch (https://github.com/mysensors/NodeManager/tree/development) and will be generally available only when NodeManager's v1.7 will be released (it will take I guess still a few months).

    Since this change was blocking other pending changes, I hope now the development will be faster and feel free to submit your PRs now that the new architecture has been finalized.
    As always, any feedback is more than welcome.

    closed Architecture review #229

  • Hardware Contributor

    @user2684 Thanks a lot for the architecture change, which makes a lot of sense conceptually.

    Unfortunately, it appears to use more memory than before. I'm working on an air quality board with eight MQ sensors, an MH-Z19 CO2 sensor and a Plantower PMSA003 particulate matter sensor. In previous development versions (1.7-dev, before today), the eight MQ sensors and the MH-Z19 worked fine, but now after your big merge of #229 the sketch appears to run out of memory after adding the child of the sixth MQ sensor. Do you see any chance to optimize for memory?

    Old sketch (using a previous development version of NodeManager, without the PMSA003; 155 bytes left after all nine sensors are fully initialized): https://github.com/open-tools/NodeManager_GasSensor/tree/master/NodeManager_GasSensor

    New sketch (using the latest version of NodeManager, plus a PMSA003): https://github.com/kainhofer/NodeManager/tree/GasSensor
    That sketch runs out of memory with the sixth MQ sensor (I added debug output with free memory at a lot of spots). Of course, I have commented out the PMSA003 completely to have a correct comparison.

    FWIW, the sketch is for this board: https://github.com/open-tools/NodeManager_GasSensor/blob/master/images/IMAG2267.jpg

    @reinhold if you have high memory requirement, what about switching to a more modern architecture like stm32f103c8t6 on the famous "blue pill" boards ? It has 20k or RAM (10 times what you have on Arduino) and 64k of flash and it's supported by MySensors, in addition to be very cheap (2$/board). You will need voltage converter between 3.3V of the board and 5V of your sensors but that's not a big deal in exchange of the possibility to expand your board with more sensors in the future.

  • Mod

    @reinhold not sure how much this applies to NodeManager, but there are some recomendations for reducing memory footprint at https://www.mysensors.org/apidocs-beta/group__memorysavings.html

  • Hardware Contributor

    @nca78 Thanks for the suggestion to use the blue pill STM32 boards. I haven't thought of it (I only looked at the ESP8266, but that has only one ADC). I have a few lying around here, but never got around to trying them, as I first need to burn the bootloader. It looks quite promising, but the boards are huge, so I'll need to enlarge my PCB...
    The need for a 5V->3.3V regulator is no issue, as the NRF24 already needs 3.3V. The 5V analog level of the MQ sensors will need some converter (the analog ADC inputs are marked as non-5V-tolerant...), but then in turn I can get rid of the voltage dividers for the PMSA003. The larger issue seems to be the connection of the nrf24, which takes away 4 ADC pins, so there are only 6 ADC pins left, while I have 8 analog sensors 😞

    Still, for now I have the PCBs with the ProMini, so I'll try to strip down the Sensor or SensorMQ classes for my own use.

  • Hardware Contributor

    @nca78 Two more things popped up with the latest development version of NodeManager:

    • In NodeManager.ino: function void before(): The sample code to set the child id of a child is sht.children.get(1)->child_id = 5, but that does not work, because at that point the children are not yet even generated. They are created by the node.before(); call at the very end of the function... So, currently this will not assign any new child ID and the default IDs will be used. I have not checked in detail whether calling node.before() at the beginning of the before() function and then assigning child_id to the children will solve the issue. From a quick look at the code, it might work...
    • I'm trying to implement an OLED display, where the node would wake up every 5 seconds, take a measurement and display it on the OLED. But the report interval to the MySensors gateway should only be 10 minutes. I thought that
      node.setSleepSeconds(5); node.setReportIntervalMinutes(10); would be the correct way to setup NodeManager to take measurements every 5 seconds, but only report it every 10 minutes to the network. Unfortunately, Sensor::loop(MyMessage* message) seems to immediately return without measurement if the reporting timer has not elapsed. Somehow I don't understand that logic. Why have different sleep and reporting intervals when measurements will only be taken at reporting intervals anyway? I would expect measurements to be taken with the sleep intervals (e.g. to calculate an average over the whole reporting interval) and report back to the network using report intervals.

  • Contest Winner

    @reinhold thanks for reporting this issue. One of the main objectives of the new architecture was to reduce the memory footprint so if this is not the case, there is definitely something to fix. I've noticed in your sketch you are using the remote configuration sensor, that one is huge in terms of memory, if not strictly required I'd comment it out (BTW very nice project!). In PR #229 I've also uploaded a spreadsheet with all tests I run for realizing what was using the memory the most. Anyway, there is still a lot of room for improvement looks like 🙂
    Thanks @mfalkvidd , I'll give the directives you pointed out a try!

  • Contest Winner

    @reinhold you're right, assigning the child_id before calling node.before() does not work. The way to go would be to have all the methods being called before node.before() and the child_id assigned just after. Not very intuitive, I probably need to find a completely different and a better way to do so, probably by creating the Child in the constructor instead (reopening https://github.com/mysensors/NodeManager/issues/198 for this).

    Regarding setSleep and setReportInterval, measurement are driven only by setReportInterval. Those are different because there are situations (e.g. relays, motion sensors) when you have nothing to report but you want the capture the heartbeat from sleep(). What you are looking for is something I never considered which is actually a pretty nice idea (taking measurements over a given time period and than reporting at the end). I've created https://github.com/mysensors/NodeManager/issues/243 for this. With the new architecture, since keeping already track of the average within Child, should not be so difficult even if would probably require an additional Timer. Thanks!

  • Hardware Contributor

    @user2684 Thanks for the spreadsheet with your memory footprints. Are these the sketch size and the free memory that the compiler reports? Or do you measure them when running the sketch (i.e. including all dynamically allocated variables in SRAM)?

    Also, one problem you don't seem to have covered is heap fragmentation. Particularly your new List class seems to be prone to heap fragmentation with a large number of sensors: each time a sensor is added, the list needs to re-allocate the memory for its pointers. The old memory will be released, but it will remain as a hole in the memory, where new variables might be allocated. However, the next time you add an element to the list, the new pointer array can probably not re-use some of those freed holes.
    I'll provide a PR (https://github.com/mysensors/NodeManager/pull/247) that adds an allocateBlocks(count) method to the List, which can be used in the sketch and in the sensor's onSetup methods to pre-allocate the required sized. In turn, the _preAllocBlocks member does currently not serve any purpose, and I don't think it's really required functionality. In my eyes, it's more important to ensure that at a certain moment the required memory is allocated. It is not neccessary to keep a minimum nuber of blocks allocated at all times.
    For a node with 10 physical sensors (and maybe one or more built-in sensors), this will save at least 22 bytes (1,1% of total SRAM!) and probably reduce heap fragmentation by quite a bit.

    Another are where >22 bytes can be saved is the power manager. None of my nodes makes use of the power manager, yet each sensor needs to keep a (null) pointer to a power manager. Providing a compiler #define NO_MODULE_POWER_MANAGER can exclude everything PowerManager-related from compilation and save one pointer per sensor and node, i.e. with 10 sensors you'll save another 22 bytes (1,1% of total SRAM!) I'll provide a PR for this, too: https://github.com/mysensors/NodeManager/pull/248

    Apart from that, I simply stripped down the SensorMQ class and removed all configurability for my own use (don't worry, I won't submit this as a pull request... it is simply meant to squeeze the sketch onto the pro mini with the boards that I have already built).
    BTW, the SensorConfiguration is no problem as far as SRAM is concerned (it just adds the normal SRAM footprint of a Sensor instance): It has no class members of its own. Only the flash size is considerable, but for me this is not the issue, I'm running out of SRAM.

  • Contest Winner

    @reinhold I measured only what the compiler reported. Main focus was to reduce the flash size, I honestly ignored any potential SRAM issues which is bad 🙂 Thanks for the hit and for the great contributions and PRs so far. You're right about the List class and especially when the number of items is known, there is not reason why not allocating the blocks beforehand. I will merge your changes as they are and then take it back and adjust something (e.g. make the number of block you are passing to "node" optional, moving child creation into the constructor, always allocating the blocks for children in each sensor, generalizing a bit more the NO_MODULE thing etc.). Thanks again!

    Hi, for those looking for making NodeManager time aware (with and without an attached RTC), this capability has been added to the development branch through https://github.com/mysensors/NodeManager/pull/259 and it is of course transparent to the end user. When this feature is enabled, also, the node resumes the remainder sleep time when woken up by an interrupt and allows SensorPulseMeter and subclasses to support sleep mode. Thanks

  • Plugin Developer

    @user2684 Great news! I will give that a try shortly.

  • The SensorSwitch/Door/Motion all work on interrupt pins only ? Sorry if I've misunderstood the code, thats possible.

    Anyway I've made a few changes so that busywait, if thats what they are called buttons can be also used. I'll see if I can use git somehow to share the changes, or show them at least

    Great library, looking to convert other things to use this.

  • Great code, another question.

    For the SensorDimmer, each sensor has only one type set so a dimmer can't receive v_status & v_percentage messages.

    I've worked around this by registering two sensors at the same Analog out pin. But they don't then have access in a nice way to the status of each other as values are changed. So if I turn the led on/off via the v_status message I can't preserve the previous percentage, set by the other v_percentage sensor.

    Is this normal ? I'm new to all this but at least mycontroller lets you specify for a single sensor both v_status,v_percentage so both types of messages can be sent and processed in onRecieve()...

    Perhaps some enhancement on the SensorDimmer class could do this ? in ModeManager.cpp (if (message.type != _type) return;) inside Sensor::recieve.... isn't that too restrictive ?

  • Contest Winner

    @rfm69 yes, they are all interrupt-based. Reason is they would need to be functional either when sleeping or not so I went for this approach. If you need an example of such a sensor not interrupt-based, have a look at the SensorSonoff, it is using a different approach for handling the button. Thanks

  • Contest Winner

    @rfm69 you're right, this also came out a while ago. I was sure we had an associated issue on github for this but it doesn't look like. Here's the new issue for your reference https://github.com/mysensors/NodeManager/issues/296. Implementing this in v1.6 is really challenging but with the new v1.7 architecture of the development branch should be way easier since all the children share the same variables. Thanks!

  • @user2684 Thanks, I've implemented something myself with changes to the library, just playing around to understand it better. But will look at the SensorSonoff you mention.

    Thanks again, its a great library.

    Had a quick look at 1.7 dev branch 🙂 is this ready for using already, testing or trying, or have you got more to do before its refactored etc ? I was interested in looking what the changes in architecture were.

  • Contest Winner

    @rfm69 v1.7 is still not completed but theoretically fully functional and with most of the architectural changes already done (https://github.com/mysensors/NodeManager/milestone/9 for the full list of things still to be completed and those already implemented).

    @cpl_ir super weird, looks like the linker cannot find NodeManager's object file. Are you sure all NodeManager's files are within the same directory? NodeManager cannot be installed as a standard Arduino's library but all the files need to be in the same directory of your main sketch. Thanks!

  • Hello, I have been experimenting with the door sensor example and have configured to wake up every hour to send a battery voltage (V_VOLTAGE)
    It will also wake whenever the interrupt state on the switch pin changes. I noticed that when the node wakes up with an interrupt it seems to send three events:
    V_TRIPPED (this is the important one)
    this is all good, however for my application it would be useful if it were to also send a V_VOLTAGE battery measurement along with the V_TRIPPED event.
    I'm not yet completely familiar with how the nodemanager sketch links together, but is it possible for the sensor readings for all sensors to be sent on an interrupt from any other sensor so I can make use of the radio as much as possible?

  • Contest Winner

    @arthurdented the I_POST_SLEEP_NOTIFICATION and I_PRE_SLEEP_NOTIFICATION are due to smart sleep which is on by default. Regarding the V_VOLTAGE I think what it comes closer to your need would be a SensorBattery configured with a very short reporting interval but regardless, when an interrupt occurs, no sensors other than the one associated with the interrupt would execute their main function.

  • is there a possibilty to only send values if the value has changed?

  • Contest Winner

    @felix-haverkamp the signal node is supposed to send the RSSI when the radio supports it. What you are looking at is a v1.7 bug, fixed in the dev branch of v1.8. If you want an easy fix without the need to upgrade, just remove the uint32_t cast at line 5017 of NodeManagerLibrary.ino (https://github.com/mysensors/NodeManager/blob/master/NodeManagerLibrary.ino#L5017).
    To send the values only if the value has changed, you need first of all to turn FEATURE_CONDITIONAL_REPORT on, then you can use setValueDelta() and setForceUpdateMinutes() of the Child class to achieve what you are looking for

  • @user2684
    thx, that is what was what i am looking for.

  • @user2684

    would be nice for other users to document this function. With this i am able to only send values to the gateway when its changed. Using it for a Light Sensor and dont need the value every 10 seconds and not every 10 Minutes....
    Just when it changes (1 second) and only when it changes.

  • Contest Winner

    @felix-haverkamp if you set setValueDelta() to e.g. 0.1 or 0.01, then the sensor will not report if the value has not changed, if I have understood correctly your point. setValueDelta() will set the minimum difference (+ or -) that the new value should have in order to be reported. Let me know I've misunderstood something. Thanks

  • @user2684 i just mean, we have to put this is the documentation.

    currently i have a strange problem:

    the Motion Sensors doesnt reset. I checked with my old Motion sketch and everything is fine.
    Only sends the Value "1".

    @felix-haverkamp got it, thanks, I've opened this issue https://github.com/mysensors/NodeManager/issues/366.

    Regarding the sensor motion, weird, by default should attach to CHANGE interrupt so to intercept both. Any chance to share NodeManager's debug log as well? Thanks

    i think conditional report is the problem:


    without it works fine.

  • Contest Winner

    Every new version of NodeManager, I try to review and hopefully improve its architecture. This time looked like a simple and quick task but eventually ended up in a complete and deep review of the code. Many many many things have changed with the main objective to better integrate with the MySensors library and simplify the life of users willing to contribute or to add support for new sensors.

    The new file structure (with a dedicated file for each supported sensor) and the way the package is delivered (as an arduino library now) go into this direction. There are also included a good amount of new features but still in most of the cases, resulting a smaller code.

    All the details are available at https://github.com/mysensors/NodeManager/pull/391 which will be merged into the development branch shortly.

    Due to the many changes, if anybody would be willing to give it a try and report any bug, would be really great. Thanks!

  • Plugin Developer

    Just wanted to say that NodeManager is awesome. I can't believe I only now really had a better look at what it is. I always thought it was some kind of software you had to install, and that it was used by professionals to manage complicated sensor nets.

    For the last few months I've been thinking "wouldn't it be useful if there was some kind of beginner friendly web interface where you could select which devices you want, and then it creates the code for you". This is so close to that. Thank you for this incredible work!

  • Is it possible to "force" send SensorDoor value regularly?

    I am using magnetic sensor together with interrupt feature but when sensor status is change too fast before main loop is finished, sensor value remains in wrong state until magnetic sensor value is physically changed again.

    So I would like to set that SensorDoor value will be set regularly like e.g. temperature sensors values. I tried to add:


    But it does not work in this case. Value is not reported based on this interval. Only way how to get SensorDoor value back to right state is physically change its value (open/close magnetic sensors).

    Btw Nodemanager is really awsome. Great work!

  • Hi, I need some advice for my following problem..:

    Situation: Arduino ist connected to an raspberry gateway with openhab -> works just fine.
    To the arduino I have connected a PIR on 3 and a photoresistor (LDR) with an 10k resistor on A0 -> works just fine.
    On first boot (after connecting etc.) the arduino sends motion status + LDR value. But after that first msg. only the motion (tripped) is send.
    What I want: I want that the arduino sleeps until there is an interrupt comming from the PIR and then sends the motion status+light value (LDR) and then sleeps again 4ever until the next interrupt.
    Problem: As I said, it only sends the light value only once.. and then never again. On the arduino debug I can see, that only motion is send:
    NodeManager v1.7
    LIB V=2.3.0 R=N E=X T=N A=A S=S B=-
    LDR I=1 P=16 T=23
    MOTION I=2 P=1 T=16
    PRES I=1 T=16 D=LDR

    MY I=5 M=255
    INT P=3, V=0
    INT P=3 M=1
    INT P=2 M=255
    MOTION I=2 P=3 V=0
    SEND D=0 I=2 C=0 T=16 S= I=0 F=0.00
    LDR I=1 V=352 %=34 <-- first an last time LDR sends it's value
    SEND D=0 I=1 C=0 T=23 S= I=0 F=0.00
    INT P=3, V=1
    MOTION I=2 P=3 V=1
    SEND D=0 I=2 C=0 T=16 S= I=0 F=0.00
    INT P=3, V=0
    MOTION I=2 P=3 V=0

  • @fausti
    ok, I have solved it myself - the PIR made all that trouble.
    I did connect the PIR on 3.3V (similar to https://forum.mysensors.org/uploads/upload-4bdca27e-3c36-4c68-9e54-947b9f4717b4.jpg).

    Problem was, that when arduino wakes up the radio, the power drop would kinda restart the PIR, which causes an interrupt. Think a similar problem was discussed here:

    Anyways - you surly would have helped, if i would not have found it. Great forum! 🙂

  • Contest Winner

    @jiri-hron I think you can achieve what you need by using FEATURE_TIME. In this way when woken up, NodeManager will go back to sleep only for the remainder time left. Not ideal but I couldn't find a better way to understand for how long the node has been sleeping before the interrupt.

  • It looks like there is a limit of 1 type of each sensor. Is there a way to modify this?

    My use-case is a french sliding glass door. I would like to use a single node with 2 magnetic sensors (one on each end of the node) with the node mounted in the middle of the door, so that if either side is moved the interrupt is triggered.

  • Contest Winner

    @iteafreely your understanding is correct. I see two options here: you can either create a new custom sensor inheriting from SensorDoor and adding an additional child and the extra logic you require or create two instances of SensorDoor and playing with hooking functions to make one checking on the other. In this latter case you probably need some additional variables to keep track of the status.

  • Hardware Contributor

    @iteafreely I don't think there is a limit of one sensor per type, not even for interrupts like door sensors. You just need to make sure you are using different pins and different child ids for the two magnetic sensors. I'm using 8 analog sensors (MQ-... gas sensors) on eight different pins on the same node and it works just fine.

    Of course, if you need some interdependence on what the two magnetic sensors report, then you must follow @user2684's suggestion of creating a custom sensor (a C++ class derived from an existing sensor class).
    But if you simply want two independent magnetic sensors (for each of the ends of your sliding door), then you can simply create two instances of SensorDoor on two different pins (here pins 3 and 4) and different hardcoded child_id (1 and 2 in this case):

    SensorDoor doorLeft(node,3,1);
    SensorDoor doorRight(node, 4,2);

    Unfortunately, both of them will report to the gateway with name "DOOR" (and there's no way to change it without subclassing SensorDoor), but they will have a different child_id 1 and 2 to distinguish the two values sent by the node.

    You can then use your smart home controller to handle the two door sensors like one.

  • @iteafreely Not sure of software issues as I don't use NodeManager, but your use-case indicates you do not need to know which door is opened, only that one or both is/are.
    If by magnetic sensor you mean magnet/reed, would a single reed where both doors meet, or two reeds (one on each door end) wired in parallel, to a single interrupt pin not provide this?

  • Contest Winner

    @reinhold just for completeness, that "DOOR" can be customized too by calling setDescription() of the (only) child of the SensorDoor instance. Thanks!

  • Hardware Contributor

    @user2684 Right, thanks for pointing this out. I mixed up the child name that was sent to the controller (which can be changed by e.g.

    void before() {
      doorLeft.children.get(1)->setDescription("Door Left");
      doorRight.children.get(1)->setDescription("Door Right");

    ) and the sensor's _name field, which is printed to the debug output. That "DOOR" debug output cannot be changed without subclassing. But as this is just debug output, it's just a minor nuissance.

  • Contest Winner

    @reinhold oh you're right I didn't even noticed that DOOR would show up in the debug output, thanks. Anyway with v1.8-dev this should have gone since debug output has been completely re-worked (and made compatible with https://www.mysensors.org/build/parser). Thanks

  • hello, I wanted to use the function for FEATURE_CONDITIONAL_REPORT for an LDR sensor but except a value when starting the arduino, no more values are transferred, must be configured for the function specifically something? Node manager 1.8dev

  • Contest Winner

    Hello all, NodeManager v1.8 is almost ready and likewise with the previous releases I like to give brave users a few weeks to test it out before actually releasing it. If you are one of those, download it from https://github.com/mysensors/NodeManager/tree/development; for a full list of changes, have a look at https://github.com/mysensors/NodeManager/projects/2.

    Of course feel free to open a ticket on Github for any issue you could come across. Thanks!

  • Re: 💬 NodeManager

    Hi @user2684,
    Hi all,

    First a great compliment for this work! This should make things just easy, but...
    It doesn't work for me. I have Ethernet Gateway and a 1wire Tempsensor node. Both flashed with the sketches from tutorials found on the mysensors.org website. Those are working without any problem.

    Now I have Tsl2561 Lux sensor. This is supported by nodemanager. Just downloaded the latest dev version uncommented two lines as expected, but it the node won't appear.

    The sketch looks as followed

    * The MySensors Arduino library handles the wireless radio link and protocol
    * between your home built sensors/actuators and HA controller of choice.
    * The sensors forms a self healing radio network with optional repeaters. Each
    * repeater and gateway builds a routing tables in EEPROM which keeps track of the
    * network topology allowing messages to be routed to nodes.

  • Did same body the port on Intel Edison? Arduino IDE is not finding SerialPort.h ?

    @maddinthebrain sorry for the huge delay...would you mind sharing the logs? Also feel free to open an issue on https://github.com/mysensors/NodeManager/issues with the logs. Thanks!

    Hello All, NodeManager v1.8 has just been released! I've opened up as usual a dedicated thread on the forum containing all the details of new release: https://forum.mysensors.org/topic/9944/nodemanager-v1-8-now-available

  • Question about PowerManger:
    I am a bit confused or I can't find the right information.
    I have an Ultrasonic sensor (SensorHCSR04) that needs to be only powered in case of measuring, due to power consumption.
    An the sensor needs to be switched on a time before the actual measuring starts.
    So my first approach was to switch the
    Then I set


    Where I a a bit surprised, why I need two pins (for vcc and ground)?
    At what logic level are the when the PowerManager switches to ON or OFF?
    Do I need to connect both pins, or is the vcc- connection enough?
    Anyway, somehow it did not work with me. It seemed, that the pins are not switched in that way, that pin5 goes to ground and pin 6 goes to 3,3 volt.
    So I found that thing :

    // power all the nodes through dedicated pins

    But here is no timing possible.
    Am I missing something?

    @rpunkt you don't necessarily need to use an additional pin for ground, just set the value to -1 in case you don't need it (https://github.com/mysensors/NodeManager/blob/master/nodemanager/PowerManager.cpp#L34). The logic is when PowerManager is set, at the end of a sleep cycle, the virtual vcc pin is set to HIGH and all the sensors' loop are executed, then is set back to LOW and board goes back to sleep.
    To use it for all the sensors try just with:

    PowerManager power(5,6, 500);

    Also ensure the sensor can work with the limited current the arduino's pin is able to provide. Thanks

  • @user2684 Thanks for the advice. Now I got it running.😋🙏

    Hello, it is me again. Going the next steps.
    Now I want to operate another sensor (SensorVL53L0X).
    this sensor should transmit the distance and the battery voltage every hour. in between it should sleep.
    The normal reporting interval of the battery is once every hour
    I set setReportIntervalHours(1); to report the sensor value.
    But how do I set the node to sleep in between?
    setSleepOrWait(True); and sleepBetweenSend(); ?
    setSleepOrWait(True); and setSleepMinutes(60); ?
    And is the NodeManager so clever that all the transmits are at the same time,
    meaning once every hour the sensor value and the battery voltage is transmitted.
