Ventilation: Shelly 2.5 with 3-level switch - ESPHome - Home Assistant Community

Hi, I’ve created a yaml config file for the following config: Venitlation unit (in my case a Storkair WHR 930), controlled via a Perilex Plug Old-fashioned 3-level switch to control the ventilation unit Shelly 2.5 to controll/influence the 3-level switch These ventilation units are controlled relatively simple: -when L1 is live/hot, the ventilation unit goes to medium -when L2 is live/hot, the ventilation unit goed to high -when L1 and L2 are not live, the ventilation unit goes to low -i

Home Assistant and ESPHome automatically ventilate my home when CO2 levels are high : r/homeassistant
