After running HA for 2 years and tinkering with the stuff I already had, it was time to extend the little machine via Zigbee. I got an Aqara Temp/Humidity/Pressure sensor, which in itself works fine. It just chewed through 30% of battery in 4 days. Now that might be an issue with placement and signal strength (basement through 2 floors), but it doesn’t bode well unless it “levels out” at some point.

Which brings me to my actual question: does anyone know any such sensors that are wall-powered in any way? Something that can be plugged in and “forgotten” about?

    I have built myself some sensors using Arduino or similar microcontrollers (ESP32, ESP8266) and have them powered via usb with regular phone chargers. It usually requires soldering and writing code, but once you are there, there’s no look back. There are ways to simplify the coding part, and HA has good support for them.
