FYI: Added the NodeManager project under the download/api section on the main site.

Keep up the good work!

How make not sleep sensor?

void NodeManager::loop() {
#if SLEEP_MANAGER == 1
Only for sleep
#end
}

May be to make wait logic

user2684

@Ivan-Z there should be already something in this direction available. You still need to load the sleep module and set sleep time but you have to set sleep mode like this:

nodeManager.setSleepMode(WAIT);

And the library will use wait() instead of sleep(). All the rest will stay the same.
I probably need to double check if there is anythig in the code which will use sleep instead of wait outside loop() so I've opened https://github.com/mysensors/NodeManager/issues/38 for this but you should be ready to go even with the current version.
Thanks

Please show my sample with DHT22

Append optimization flag.
For save battery life, do not send the same values

user2684

@Ivan-Z if you mean an example with DHT22, you need first of all to enable the DHT module in config.h with:

#define MODULE_DHT 1

Then just register the sensor in before() with:

nodeManager.registerSensor(SENSOR_DHT22,6);

Where 6 is the pin where the sensor is attached to. NodeManager will then create automatically two child ids, one for temperature and the other for humidity.
As written in the documentation you need the DHT library from https://github.com/adafruit/DHT-sensor-library (or install it by using the arduino IDE). For some unknown (to me) reasons I had issues in using the library from the mysensors example.

What do you mean by optimization flag?
As for avoid sending the same value, this is already available, have a look at setTackLastValue() from the documentation. When set to true, the value will not be send if the same as the previous (default is of course false). I also implemented setForceUpdate(), to force to send an update after the configured number of cycles, as many examples here are using this approach.

Hi, I've updated the project (including files and documentation) to version 1.4.
Main changes are:

Added support for ML8511 UV intensity sensor
Added support for MQ air quality sensor
Added ability to manually assign a child id to a sensor
Ensured compatibility for non-sleeping nodes
Ability to control if waking up from an interrupt counts for a battery level report
When power pins are set the sensor is powered on just after
Service messages are disabled by default
Bug fixes

Thanks!

@openhardware.io Great idea. Can we expect to see support for Sonoff/ESP8266(without SLEEP) in a near future?
Also, would love to see an example of a custom sensor/HC-SR04 distance sensor, 3-pin implementation.
Keep up the great work.

Thanks for the advice! I'd be very happy to support any sensor which would be useful for the community! I've opened https://github.com/mysensors/NodeManager/issues/63 and https://github.com/mysensors/NodeManager/issues/62.
Since I don't have those sensors and delivery is kind of a pain, would you like to give me a hand in testing the code I can put together? If so, please add a comment on git with some sample code and I'll integrate it into NodeManager straight away for your testing.
Thanks!

@user2684
If you send me your paypal email, I'll forward community donations to help you buy a sonoff and HC-SR04 for testing.

@user2684 Good work with NodeManager, greatly appreciated by "MySensors noob" like myself! :+1:

This version already allows wizard (.php) to generate a sketch

I spend some time in the forum but still I'm struggling a bit to understand the Sonoff use case to then buy the right piece to test. Is it related to what has been discussed in this thread?
https://forum.mysensors.org/topic/5858/sonoff-relay-using-mysensors-esp8266-wifi-or-mqtt-gateway
Thanks!

@user2684 I have a sonoff and have posted a few examples here https://www.mysensors.org/build/sonoff, nodeManager would maybe save a few lines of code for the end user but you will have quite a lot to code :smile: I guess if you add esp8266 support, the sonoff is just a relay with a LED and a button which nodeManager already supports.

user2684

@Straydog just to be sure I'm buying the right sensor, I can only see HC-SR04 with 4 pins on aliexpress I guess this is the right sensor but I will use only three of the four pins, is it the case?
Thanks

Cool project, I wonder how I've missed it so far! I understand the idea, basically the sonoff runs as a gateway (otherwise would require a radio attached which is not possible/easy) and has a relay type of sensor attached. I think I can make it easily, I'm ordering a sonoff right now so to test the implementation. I need this https://github.com/mysensors/NodeManager/issues/65 first of all and then I can adapt the SENSOR_RELAY which is already available in NodeManager. I'll keep you posted while I will progress.
Thanks!

@user2684 It's the regular HC-SR04, with ECHO & TRIGGER soldered together. I believe you can get them in either 5 or 3.3V
There are only 3 exposed pins on the SonOff SV, I need the other pins for other sensors.
Would like to help you test this project, tried to sign up to GIT yesterday but all Usernames came back as in use, will try again.
Two issues 1) AVR/EEPROM is not found, with PERSIST 0 & board ESP8266. 2) Don't know how to define HC-SR04 as a custom sensor, or can disguise it as another sensor type, with a PulseWidth.

Great job

Straydog

@user2684 You mean, why use SonOff?!?!
In my case I want to have sensors I can control over the Internet i.e. SonOff for the garage door opener(RELAY), with a PIR and HC_SR04.
I also prefer the SonOff/ESP8266 as it has more memory than the Arduino.

Great, so if I order the HC-SR04 with 4 pins I should be ready to go. As for the Sonoff, I'm working on it right now, I need to add a few conditions here and there to have NodeManager running as a gateway but it is not that complicated. I'll let you know when I have something ready to test, can be quicker while I'm waiting my sonoff to be delivered.
As for the Sonoff use case it took me a while because it was not clear to me why a gateway and not a node but now I can see it clearly. And btw I needed something similar at home so I'll explore it even more ;-)

Way too cool solution :dancers:

I decided to give it a go with my Light/Baro/Hum/Temp node.
Installed the dependencies from Adafruit, cleared EEPROM, compiled and flashed - no issues :+1:

The node reports the expected sensors to MyController.
The BH1750 light sensor works like a charm, but I'm not getting anything from the BME280 except from a 0.0°C reading on temperature (which, even though spring is pretty lousy so far is a bit on the low side for my office).

The node was running fine for months using the same BH1750 library, but the BME280 library by Tyler Glenn.

Any ideas?

Should notice that I'm using this kind of BME280 from Ali

user2684

@ksga I can see from the logs the light sensor correctly returning something but the BME280 apparently only able to get the humidity. I also see the node rebooting itself at a certain point. Was it you resetting it? Because if it was not you, it may be due to the memory almost full and when this happens, the behaviors I've seen are really unpredictable including weird numbers reported. To start with, I'd recommend to disable NodeManager's debug which will save some memory and see on the controller if the data returned is correct. If it is still not correct, do you set any specific i2c channel in the other sketch where both the sensors are working fine? I wonder if there is any difference between the two sketches.
Also, are the sensors powered by pin 6 and 7? If so I'd power them directly just to take away this variable at least for now.
Thanks!
