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 use the aqara motion sensors and the battery sensors plummet almost immediately to 70% but then stay there for months. I’ve had them for over a year now and they haven’t been a problem.

      Interesting, thanks. I’ve hit the 70% yesterday, let’s see when/if it moves from there any time soon.

    I know this is an old question, but the Shelly H&T has a USB power cap that you can buy separately. Then use any micro USB cable and power supply. It’s Wi-Fi and not zigbee, and it is definitely a tad more expensive per unit. However, no need to worry about batteries. Shelly does run sales occasionally too.

      That was the first one I tried. Sounded fantastic in theory, didn’t work out for shit. For some reason the sensor dropped out constantly. The USB PSU bottom was nice though, no batteries to change.

        I do find that they go to sleep fairly often. I changed the temp update setting to the smallest value and it updates fairly regularly. If the temp doesn’t change much I don’t think you get an update.
