Hi, all this is awesome, about the same what I would like to make as I'm heating the house with wood boiler (actually wood gasification boiler to be correct), and accumulation tank. Still working on hot water boiler, but that's not far.
For now, I got working Individually DS18b20 node (still with automatic addressing) and one node that reads the temperature in my boilers second burning chamber with a k-type thermocouple but still struggling to get them bout working with one node.
It would be very helpful for some guidance or example for this.
So my goal is to get 2x thermocouples (additional for smoke temperatures) and some 18b20s in one node + some standard stuff what I am not still sure about.
But for now big thanks to mysensors team and community for this.
