GoveeLifeE-Ink Bluetooth Thermometer Hygrometer, Smart Digital Indoor Wireless Temperature Humidity Sensor with Alert, Free Data Storage Export, for Home Room Greenhouse Wall, 2 Pcak (with Battery)

Simple device for temperature and humidity. I like the size and overall look. It's accurate, I compared it to another sensor I had and they both have the same readings. I always wanted to try/see one of the E-ink paper displays and it's really very easy to read. I am not using any of the connectivity features to my phone, I did not buy this for that use.

Got this to monitor my guitar room humidity. This device allow me to monitor the room temp and humidity. Also send notification on my phone when the temp or humidity exceed or drop below my preset limits

I own another Govee temperature product and discovered that it came right up on my HomeAssistant home automation software setup. This was a pleasant surprise as I was expecting to have to invest in something much more expensive in order to add more home automation sensors to my house. So I bought a three-pack of these e-ink type temperature/humidity sensors and they also came right up (after a simple config in the HomeAssistant software). I don't use the Govee phone app at all and can't speak to that but the fact that these units come right up with zero fuss in other home automation software makes me very happy. Now I have four total Govee sensors measuring and graphing the temperature ranges in various parts of my house and an outdoor greenhouse. The e-ink is very visible in comparison to an LCD based screen (like my home thermostat pictured here). I love the ease of reading this unit. Also seems to be the same accuracy as my HVAC thermostat. Might pick up another pack soon.

Doesn’t always connect with my phone

When I first opened the box, I was disappointed in the small size. I wanted something I could see from across the room. I was surprised when the numbers were very clear from across the room. I’m very happy with his little temperature gauge.

These things are really cool, and at the price point I decided to buy 5 for Home Assistant integration.What I like:- E-ink displays!- Form factor- About the lowest battery consumption you can ask for from something with a live display.- Instant integration with Home Assistant- Completely local, not cloud-reliantWhat I don't like:- Temps take a long time to settle fully... Like 15mins or so.- Not very precise from the factory. I had about a 1*F variance between all 5 units.- Very sensitive to body heat (can't move it/touch it or you'll throw it off for 15mins until it settles again)- Calibration is only possible currently through their app, which means you give them all sorts of permissions/data before you can even attempt to add a device. What this means for the long term is if they go defunct, you better hope you have an APK stored somewhere, a phone from the same era, and that the app works offline.- Non-recharable coin cell battery. To make this the most ideal device possible, I would like to see a small solar cell integrated somehow that can keep a battery topped off, or even run solely off of (like calculators used to have)

Screen is clear and it is durable but the temperature runs about 10 degrees F warmer than what it actually is, so as long as I keep that in mind when using it, it’s not a problem.

So glad I got this one, it's exactly what I needed. The Bluetooth was something I didn't think I wanted but it's been really handy for me. I keep most of my plants in my office room and sometimes need to keep (non-grow) lights on late into the night, I have a blackout sheet that I use to keep the room light off the plants. While the sheets up I use the Bluetooth monitor the humidity and temps, which ends up being pretty often. The ability to save records I found pretty neat too.The E-Ink display is easy on the eyes and the overall design blends right into my office. I do wish it used a more standard battery, like a AAA or AA, VS the button battery. But that's just a minor personal nitpick.I will say I was worried at first about the accuracy, after unboxing temp was off by about 8°F for atleast an hour. It is possible to recalibrate, which is a VERY handy feature, but only up to 5 or 6°. Ended up leaving it be over night and it's been perfectly fine ever since, seems like just needed time to aclimate or something.Anyway highly recommend and I'll definitely be buying again, when my collection inevitably starts spilling into other rooms.
