@Faris-Sabri-II It reads the battery voltage.

by looking at the picture the voltage is measured near the battery, so I'd say it is the battery voltage

@NeverDie I used ethernet cable as an audio cable so later I can use those 6 unused pins something else.

Hello, I you are interested in the full integration with Brink Renovent HR, please have a look here: https://github.com/raf1000/brink_openhab/blob/main/README.md The integration is with openhab but similar one can be done with home assistant I suppose (mqtt) It is tested with Brink Renovent HR, but Brink Renovent Excellent has the opentherm protocol available as well...

@clivec If you look in the MySensors code, wifi is not an option for the radio transport. You'd have to somehow write your own deal for that, and it would likely get really involved. ESP32 is supported for a gateway, where the wifi is the backhaul transport, effectively, but you would need a separate radio for the MySensors side of things. To use an ESP32 on its own, without a separate radio, you might look into something like https://esphome.io/ This does not allow for interaction with MySensors directly, though. What is your ultimate plan? An ESP32 is very power hungry when on wifi, so it wouldn't work as a battery-powered device very well. They're pretty cheap, and easy to get a hold of, so if you have them plugged into mains power then you could use them alongside a MySensors network. Maybe with something like Home Assistant controlling both and providing a link from one to the other if needed? Maybe you haven't been getting much interaction here because it doesn't fit very well with MySensors. I've seen your previous posts, but since I haven't tried to connect any ESP32 devices to the network, I didn't have any input for you. (I prefer my backhaul to be wired, so the ESP32 wifi was a negative, in my book.) I mean, I have nothing against ESP32 for other things, but for me it has no place in the MySensors network at all.

@mrmuszynski Hi, there are some setters for message payload types but none for type String, see: Message manipulation. You need to convert the resulting String into const char* like this: send(msg.set(("string " + String(expectedScratchpadValues)).c_str())); But in general I would try to avoid usage of the String data type, especially for the use case in your code example. You could use e.g.: char str[80]; sprintf(str, "string %d", expectedScratchpadValues); send(msg.set(str)); For Arduino String read more e.g. here: The Evils of Arduino Strings HTH
