MySensors and Home Assistant - using MQTT

Mihai 14 Jan 2016, 19:40 last edited by

I have successfully built and tested MySensors 1.5 and 2.0.0 beta with Home Assistant using MQTT with slightly modified sketches , few more words here: http://forum.mysensors.org/topic/2747/home-automation-multi-sensor-nodes.
The node ID was declared manually for each node.
The topics description was not very clear from the beginning, but finally I got them and now several examples of many sensors types are included in the configuration.yaml file.
I did not succeed to make them to work together using the Serial Gateway, but MQTT is just fine (may be better from some points of view).

@HJ_SK said in 2x BME 280 on 2x arduino nano hangs in HomeAssistant: BME280 I had a similar situation. First you have to delete all the MySensors devices in HA. This is aggravated by HA wanting the devices to be on line before you delete them. You may have to delete the MySensors data in the HA config directory. You may even have to uninstall MySensors from HA. Then shutdown HA. Next, turn off your gateway. Are you using MQTT for messaging? You'll have delete the MySensors data from there, too. (MQTT Explorer is good for doing this) Then start HA. Did your MySensors devices come back as zombies? That's the problem. Try deleting them again. Are they data still in MQTT? OK, now start again. I had documented how to do all this deleting in HA Forum, HA/Discord and here, but I can't find that documentation now. grrrr OSD

Hey @OldSurferDude I think we have a missunderstanding here. I have my gateways running on ESP32. When I add the integration I can enter the IP in this dialog: If you want to change the IP number of the gateway (or the MQTT topic or the serial port), there is no way to do this:

@badisensors I have this same issue and am struggling to find a consice answer to the question. Have you figured it out? I would love to see a bit more detail about the important naming and numbering protocals for Gateways, Nodes, Sensors, and their output values within the MySensors architecture. So far, I am not finding much and progress is slow when I simply need to try different iterations and make conclusions/adjustments.

Same issue here. HA receives data from Ethernet Gateway for only a few minutes and then: DEBUG (MainThread) [mysensors.gateway_tcp] Connection lost with <_SelectorSocketTransport closing fd=42 read=idle write=<idle, bufsize=0>> I also have MYSController connected to the GW and it remains connected. There is an open issue as others are also having the same problem. Am wondering if anyone here is having success with Ethernet Gateway connected to HA.

What I did not try but might work: copy your persistence file, delete the old GW and create a new one with the persistence file you copied. Maybe the devices are preserved like this. Maybe you should create a full backup before... <edit: typo>
