Experimental: ESP Easy MySensors Edition
-
Well to be more precise: If you have a DHT (temp+hum) and BMP (temp+baro) and each value has a unique child id, Domoticz seems to create two devices but each will have three values.
What I send is this:child id 4 (hum value from DHT)
child id 5 (temp value from DHT)
child id 12 (baro value from BMP)
child id 13 (temp value from BMP)End result is two temp+hum+baro devices.
So it adds the humidity value to the BMP sensor
And adds the barometric pressure value to the DHTOr could I use the same child-id for multiple values?
I though child-id's need to be unique for each value? -
It's a bit weird they get grouped by the controller. Guess they had some nice device type they wanted to reuse.
A few device types actually allows different sensor readings. You'll find them in the last column of the presentation-table here:
http://www.mysensors.org/download/serial_api_15
I.e. For a S_BARO device you can send bot V_PRESSURE and V_FORECAST.In retrospect we probably would have splitted/organized things differently.. But this is what we have at the moment.

I think Domoticz can only work with a fixed number of combined sensor devices and it looks like this is the only way to transform data from MySensors to one of the build-in device types.As Domoticz is our main platform it would make not much sense to further develop on something that is not supported.
I don't know how other Home Automation controllers handle this. If you connect two similar DHT22 unit's to a single node, would they be able to figure out how to display this properly? Would they automatically create two devices with both values displayed. Or (I guess) they would create 4 devices and not combine them in any way?

Most controllers show them as separate devices. But I guess that if different sensor values are reported on the same chid-id it could be a candidate for combination (GUI-vise).
@martinus The last commit was in 2015. Is this going to be developed any further? I like the approach and would give it a try, if the project was still alive.

well done , but anyone here can tell me is it possible with ESP easy make network of ESP module , one in AP mode and others in Station mode ? AP module receive the sensor data of all other Station ESP module and probably send back them command or acknowledgment

If anyone answers @Hamid-s-k, please answer in https://forum.mysensors.org/topic/4053/esp-iot-net/ instead of here so we kepe the discussion in one place.

Well the child ID's are unique, but Domoticz seems to keeps on trying to combine stuff within the same Node ID and create a mess if you have more than one similar sensor attached to a single node. This renders this project useless.
This list is merged into 5 separate devices by Domoticz, creating incorrect and confusing information.There's a thread on the subject, and it the issue seems to count for native mysensor nodes too.

I think the mysensors protocol lacks some sort of group ID. If you connect two DHT22 sensors on a single node, how to tell which temp goes with which humidity if you receive 4 arbitrary child ID's ?

@martinus Anoying isn't it?
I allways give a description for each child I present. E.g.
gw.present( TEMP1_CHILD_ID, S_TEMP, "DHT1 sensor", true ); // present to controller gw.present( TEMP2_CHILD_ID, S_TEMP, "DHT2 sensor", true ); // present to controllerBy doing this I can see the description in Domoticz, so that I know what to add.
