Thank you for the insights. I do think that indeed fixing the current sensors or adding a new temp sensor would make more sense, and it is planned, but I am waiting on the order. The current temp is more relative than anything else.
I think I can work with 26.5 for now, it was just something I noticed this morning. I guess 26.5 is 80 fahrenheit ?
Good to hear about the emergency stop. i will consider RM then. I do indeed have all the heaters set to a maximum of 27c, but of course the plug needs to be running for them to reach that.
