I have a Continental Hybrid 150 Propane/Wood furnace and at present have two separate thermostats for the system. One for the gas side and one for the wood side. The system itself decides where to source the heat so that's not what I need the thermostat to do. I would like a single wall mount thermostat that allows me to set both side independent of each other. I’ve considered building a unit using a Raspberry Pi board along with Wi-Fi capabilities but am hoping perhaps there is something already available in the market to suffice.
