Smart Home DIY Thermostat (D1 Mini/DHT22/24VAC)

cults3d

This is a smart thermostat housing to be used with Home Assistant. It runs directly off of the HVAC 24VAC transformer and includes 4 relays which will accommodate most HVAC setups. The system runs off a Wemos D1 Mini, but if you have a different ESP module you'd like to use, just message me and I'll make a custom one for that module. Features: - Humidity sensor to use as a reference for bathroom vent fan automation - Temperature sensor for reference or to take the place of the thermometer in your old thermostat (for single zone setups) - Built-in cable management - Powered from 24VAC transformer. No external wires!
