💬 NodeManager

Version 1.5 of NodeManager is finally available here!
https://github.com/mysensors/NodeManager

I've done my best to implement most of the requests received so far since unfortunately I'm expecting starting from June very little spare time to spend here so I tried to hurry up a bit :-) The result is a pretty long change log and a total of 26 between ad-hoc and generic out-of-the-box sensors supported up to this release:

Added support for ACS712 current sensor
Added support for HC-SR04 distance sensor
Added support for BMP085/BMP180 temperature and pressure sensor
Added support for Sonoff smart switch
Added support for Rain Gauge sensor
Added support for MCP9808 temperature sensor
Added forecast output to all Bosch sensors
Added I2C address auto-discovery for all Bosch sensors
Added support for running as a gateway
Added option to retrieve the latest value of a sensor from outside NodeManager
Remote reboot now does not need a reboot pin configured
A heartbeat is now sent also when waking up from a wait cycle
When waking up for an interrupt, only the code of the sensor expecting that interrupt is executed
Added capability to retrieve the time from the controller
Optimized battery life for DS18B20 sensors
SLEEP_MANAGER has been deprecated (now always enabled) and setMode() replaces setSleepMode()
New mode ALWAYS_ON to let the node staying awake and executing each sensors' loop
ESP8266WiFi.h has to be included in the main sketch if MY_GATEWAY_ESP8266 is defined
Added receiveTime() wrapper in the main sketch
Fixed the logic for output sensors
Added common gateway settings in config.h

I've added upgrade instructions as well in the documentation. Generally speaking to upgrade it is safe to just replace the existing NodeManager.h and NodeManager.cpp files but with this release I had to do some minor changes to the main sketch as well, as documented in the release notes.

Thanks everybody for all the advice and for reporting any issue always in a constructive way :-)

Hi, I've added a "How to contribute" section in the documentation of the dev release in case anybody is interested to contribute to this project: https://github.com/mysensors/NodeManager/tree/development#contributing.

I'm not a git expert so I hope those instructions to have some sense :)

Very good job @user2684 ! I like it very much.
Only one thing, how I can create a simple DHT22 node? I activated MODULE_DHT, and registered like this:

  /*
     Register below your sensors
  */
  int sensorDHT_Id = nodeManager.registerSensor(SENSOR_DHT22,4);
  SensorDHT*  sensorDHT = (SensorDHT*)nodeManager.getSensor(sensorDHT_Id);
  sensorDHT->setSamples(5);
  sensorDHT->setTackLastValue(true);
  sensorDHT->setForceUpdate(5);
  /*
     Register above your sensors
  */

But when compiling it throws: 'DHT11' was not declared in this scope

I have the DHT library installed by the env, and a copy at the projects libraries folder (portable) and also at the same project folder (when opening the sketch also opens the library), but still complains.

??

user2684

@Sergio-Rius thanks! Are you sure you are using the DHT library from the arduino IDE ( https://github.com/adafruit/DHT-sensor-library) and not the one from the MySensors example folder? Thanks

Sergio Rius

@user2684
AH! You're right, you got me. I'll change and test it. Anyways the one I was using was failing frecuently reading the sensor.

But you could also make your wrapper compatible with the MyS one. The difference between both is that the later places its declarations inside the class. You can make it work by fully qualifying the calls like the example:

NodeManager.cpp @1949:       int dht_type = sensor_type == SENSOR_DHT11 ? _dht.DHT11 : _dht.DHT22;

It could be interesting if there are anyone really needing the MyS DHT library. And also it seems more memory optimized. The adafruit's are two in one and also needs another library helper in cascade.

user2684

@Sergio-Rius great idea! Will prevent people to get crazy with compile errors, thanks!
I'll track this with https://github.com/mysensors/NodeManager/issues/144

Sergio Rius

@user2684 Nevermid! I'm still struggling trying to make the TH sensor :sweat_smile:
That's the serial output I get and nothing at domoticz.

REG I=1 P=4 P=6 T=0
REG I=2 P=4 P=7 T=1
NodeManager v1.5
INT1 M=255
INT2 M=255
RADIO OK
PRES I=200, T=23
PRES I=201, T=30
BATT V=2.95 P=50
SEND D=0 I=201 C=0 T=38 S= I=0 F=2.95
PRES I=1 T=6
PRES I=2 T=7
READY

MY I=3 M=1

user2684

@Sergio-Rius ok, this is kind of a standard startup with the temperature and humidity sensors presented as child 1 and 2, so far so good.

PRES I=1 T=6
PRES I=2 T=7

By default no data is reported unless the node enters in a cycle. You would like to add:

nodeManager.setSleep(SLEEP, 10, MINUTES);

Or

nodeManager.setSleep(WAIT, 10, MINUTES);

To start getting periodically the data out. Alternatively you can send a REQ message to the child id with the appropriate V_type

Sergio Rius

@user2684 Mmmmm what if you have a motion sensor in the same node? (I'm trying to migrate my own sketch)

Sergio Rius

@Sergio-Rius said in 💬 NodeManager:

The difference between both is that the later places its declarations inside the class.

Please don't waste your time as they are not compatible. In my stupidity didn't make sure that my lib wasn't "personalized".
What a pity.

user2684

@Sergio-Rius yes, you can have a motion sensor on the same node as far as it is a sleeping node. This is because the interrupt is coming from the MySensors sleep() call. Having this compatibility in a non sleeping node is instead only planned (https://github.com/mysensors/NodeManager/issues/142)

Hi, I would like to have smartSleep for my nodes. I read that NodeManager can do that. But I couldn't find an explanation how it is doing it. I use OpenHAB as the controller and MQTT to communicate to the MySensors-Gateway. Is smartSleep working for this scenario? Did you extend the Gateway?

user2684

@strangeoptics NodeManager does use smart sleep by default. The way it works (with or without node manager) is pretty simple: when the node tells the gw/controller is about to go to sleep, it actually wait (by default 500ms I think) for new messages before powering off the radio and going to sleep. Useful if you have a sleeping node and want to communicate with it. Im not familiar with those controllers but I'm sure others are but generally speaking the way it works is the controller usually queue your messages and when the node checks in release the queue.

strangeoptics

@user2684 If I understand it correct, NodeManager is basically using the smartSleep method of the MySensors library and extended it with a default delay of 500ms after the heart beat message.
The logic for queuing the messages inbetween the wakeup periods is not implementet from NodeManager and has to come from the controller. In my case OpenHAB hasn't got the logic and smartSleep wouldn't work :(

user2684

@strangeoptics not really, node manager is not extending smart sleep at all, smart sleep from the core MySensors library by itself is implemented with this delay :)

strangeoptics

@user2684 so which controler are you using?

user2684

https://www.mysensors.org/controller/myhouse but since I wrote it, my opinion would be biased :P

The configuration service is a good ideaal.
Even better would be if it would allow setting and reading user parameters.

Hi
I have a led ir emitter can i send to my air contiotioner a code like x0284828 by digital output in nodemanager(with irremote library is simple)

user2684

@mar.conte mmm not sure I got the use case. I think we need some sort of "IR" specific output. Btw if you prefer, feel free to open a new thread on https://forum.mysensors.org/category/43/nodemanager
