Looking for temp/humidity sensors that can be wall-powered (feddit.de)

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?

30% in 4 days is ridiculous. I know some Aqara sensors have a battery drain issue, but usually it takes a month or so.

Are you using the sensor in a fridge or freezer? If the battery is cold, it'll report lower. I've had some freezer sensors sitting at 0% for months but they still work fine.

If you still want to move to a wired sensor, you can use ESPHome with a sensor such as the BME280. The boards can be had for ~$5-10 and the sensors for about the same.
