I have Home Assistant setup on a Pie4 with 10 NodeMCUV3 with DHT 22βs scattered around the house. I also have 6 Shelly devices in some wall switches and some outlets. Next up is a thermostat for my pellet stove.
I need a thermostat that has a screen to display the temp. A way to adjust it up or down without needing to find the phone. I would like to program different heating profiles in HA for different days of the week. The thermostat need to just close a dry contact when heating and open it when not. No voltage is required. Its a Pellet stove. The Thermostat could be powered by usb or 12vdc or 24v dc iβm not picky on that.
I know I could hook up another nodemcu to a relay and a dht22 and use that as a thermostat to control the stove but I really want a screen and manual up and down temp overides to keep the wife happy. She is not as much of a fan at all this as I am.
Any suggestions is welcome. Winters coming sooner than I want.
