We have frequent issues with centrally supplied hot water, so I made a simple monitor with #ChatGPT and @arduino Nano Matter. It checks if hot water pipe is cold and if so - turns on electrical heater. Otherwise it keeps heater off with #HomeKit (or #HomeAssistant thanks to #Matter).
Takes only 0,07W - will work for weeks on two #18650s 🙌.
Here's a #GitHub link:

P.S.: someday I'll get it a proper enclosure, though this looks cool to me as well 😊.
@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...
Seriously though - #homeassistant expertise needed:
1) has anyone managed to get #Cozytouch #Atlantic water heater automated? Can anyone share an example on automatically turning the heater on and off based on some trigger?
2) I added my robot vacuum cleaner via #Tuya integration and it works. But there is no apartment map and I can’t find a way to add it to HA. How can I send the robot to clean a living room for example using just HA?
3) can I use Siri on Apple devices to control HA? How?
