Do _not_ get the Aqara ones. The things will not stay connected for shit.<p>I have a couple of the Tuya ones and I'm pleased with them. The humidity accuracy is questionable, but it's fine.<p>I also have an airgradient (not zigbee, uses wifi) for high accuracy the one place I care about that. Works great in Home Assistant with esphome.
Hmm interesting I have 4-5 of them and quite like them. They've all stayed connected over a year except 1 which I just replaced the battery in and I think that fixed it. It was reporting 40% battery but would drop off shortly after connecting.<p>Aqara might be the ones with a crappy ZigBee implementation that doesn't roam right so if you move them or your topology changes, they'll drop off.
> Do _not_ get the Aqara ones. The things will not stay connected for shit.<p>+1, complete waste of time and money. I thought my Zigbee network or HA was the problem, but the sensors are just garbage.
Hah. I did something similar a while ago, but I also did full saturated salt solution humidity calibration. It's very simple to do: get several different salts, create a saturated solution in a sealed container, and observe the humidity there.<p>The best sensor in my tests was CentraLite 3310-G. It was the only one actually precise to 1% of RH and 0.1C They are also pretty robust and long-lasting.
