@arduino So I played with it for a while on #AppleHome and decided to give #HomeAssistant another try. And I even almost bought a #HomeAssistantYellow.
Luckily I didn't, because, man, it's so overcomplicated... I mean @homeassistant is doing amazing job sorting all the mess, but I couldn't either get #TVOC or #eCO2 displayed from my DIY AQI meter, nor did I manage to automate this water heater. It works well manually, but nothing happens when I run the script... So it's a 4th pause for now...
