💬 NodeManager

@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 :)
@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...

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

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)

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:

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?
https://www.mysensors.org/hardware/microalso, 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? -

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)

great.. thank you!

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.

@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.

@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.

@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.

@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!
