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?

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 tried both the Shelly ones - the HT and the HTPlus. They are both massively unreliable, they fall off the Wifi constantly, and are a hassle to try and get back (they don't come back online once they lose connection and require a partial re-setup). I had hoped being on wall power would change things but it absolutely doesn't. So I can't recommend those, sadly.

Been there, done that. And I had exactly the same experience, which leads me to believe they're simply crap.

Interested in the same but usb powered myself. For now using https://www.mylocalbytes.com/products/snzb-02-zigbee-temperature-humidity-sensor sensors. Got 5 of those but considering getting more. Had these for a couple of months but the battery still reports 100% for all of themm which is a bit suspicious and optimistic. Will update this oost once the battery will report anything other than 100.

I'd take USB-powered, not a problem. Just something that can be plugged into continuous power.

The packaging claims a run-time up to 2 years, but I assume that's for very optimistic placement right next to a hub. But who knows, maybe it's just a startup issue with reporting and it'll actually keep for a while.
