I doubt it's related to the MySensors communication. Are you using a Dallas temp sensor? Could you check that the is actually connected to the dallas sensor by using isConnected().
When googling your problem I found a few hits on -196.6 which is the error code (DEVICE_DISCONNECTED) converted to Fahrenheit.
Start debug mode (Config.h) to see what the sensor actually sends.
@mutantx, sorry for the late reply, but I was on holidays
I've no experience with this sketch code, nor the hardware build of this mp3 player.
Try to contact the author of this player or you can check the general documentation about the use of V_VARx / S_CUSTOM : https://www.mysensors.org/download/serial_api_20
Try to break up things in little pieces when accumulating knowledge about mysensors.
Big complicated sketches can be overwhelming.
I start always, when troubleshouting, with the cleanest version of the script, with minimum code required for operation. And then I build it up.
@dbemowsk I'm sorry, I really don't know. I've never tried domoticz, not to mention any of its plugins.
I do have Alexa working with my system, but I don't like it, just because of sending recorded voice out of the house all the time. So I plan to replace it once I get time to get Rhasspy going, assuming that I can get it going well enough.
Alexa works very well with home assistant. Though we use a service that costs $5/month to be the cloud piece to interact with the Alexa service so that I don't have to get something standalone working here for that. Though I think that service is really only for integrating to home assistant, so it probably wouldn't do you any good. It's saved me a bunch of time, and as I want to use my time to replace the whole thing with Rhasspy, it's been worth it to me.
But part of the reason I mention all of that is that with a quick search, it looks like controlicz is a similar service. Although they do say that you need to add the skill to your Alexa account. That would be annoying to me - doesn't that mean you need to say something like "Alexa, ask controlicz to turn on the kitchen light" or whatever?? With Nabu Casa, it also just uses the built-in smart home skill, so you don't have to install anything extra, leaving those extra words out each time. After the 10th time of having to do it I bet I'd really be gritting my teeth!
