Very easy to use and wish I got more for more rooms in the house! Very easy to use and wish I got more for more rooms in the house!

I'm using this without the smart features, since I don't have a Bluetooth hub. Without the hub, I need to hold my phone near the device to get a reading, which I may as well do with my eyes instead.

Useful to figure out which rooms need dehumidifying the most through the winter. I went back and bought more. I'm using this without the smart features, since I don't have a Bluetooth hub.

Simple and works well. I purchased 2 for monitoring temps in parts of the house. Bluetooth range is not huge but connectivity to the app is easy.

I brought this Temperature humidity meter to check room temperature for newborn and it is very useful to keep an eye the room condition. I brought this Temperature humidity meter to check room temperature for newborn and it is very useful to keep an eye the room condition.

Much smaller than i expected than in the photo’s but this is good, wanted it small just to check the temperature and humidity in the room. Much smaller than i expected than in the photo’s but this is good, wanted it small just to check the temperature and humidity in the room.

Got 2 of these now. Thought they would be a bit of fun, keeping a track on my environment. Seem accurate as far as I can test without a wet bulb hygrometer, and quick to update indications. App was a bit flaky at first and would not load or sync but ok now. No use for controlling other devices unless the are Xiaomi or compatibles. Got 2 of these now.

This one is good for monitoring room temperature. Didn't do any syncing but I'm not sure how accurate this monitor was but I'm happy that it does its job. Also, it doesn't come with batteries so you need to buy one. This one is good for monitoring room temperature.

Have got a total of three of these now, and was initially using them with the Mi app and that worked perfectly.

However, I needed more and wanted to be able to read temperatures while I was away from home so I was glad to find they are compatible with Home Assistant running on a Raspberry Pi 4. A few months on and I've flashed them with a custom firmware so they report the temperature into HA every 120 seconds (default firmware is 10 minutes) and I've coded my own bit of YAML to use them to control the WiFi connected heaters around my house, via a simple Thermostat interface.

All in all, very happy with this product. Just note they do not come with batteries and you'll have to buy these separately.

Edit 31/01/2024: There is now a way to re-flash these so that they work using the ZigBee protocol. However, I do not recommend this as the sensors appear to die a few weeks after the update and there's no way to flash them back to Bluetooth.
