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

@Multimax do you send initial states for all children for this multi relay node? HA won't show anything that hasn't sent initial data to show.

Figured it out. I had to send HVAC_FLOW_STATE to HA, in order for it to figure out that it was a "thermostat". Only problem is that it shows up with states "Auto" "Cool" "Heat" and "Off" in the dashboard, even though I only have the possibility to heat, or turn it off.
With Home Assistant as Operating System it might not work, if the radio is connected to the GPIO of the Pi. The HASS-Os has some restrictions to run software like the Pi gateway beside Homeassistant.
I have currently a setup with a RFM69 connected to the GPIO for the RPI ethernet gateway. Homeassistant runs in a container and the mysensors plugin connects in Homeassistant to localhost or 127.0.0.1. But I have problems with the stability (I think so) with this combination, as seen in this forum.
In my opinion is a Serial (USB-Serial-Converter) Gateway with Homeassistant the best choice. So I want to build another gateway and resinstall my Pi with HASS-Os.
