Govee WiFi Temperature Sensor H5179, Smart Hygrometer Thermometer with App Notification, 2 Years Free Data Storage Export, Remote Monitor for Room Greenhouse Incubator Wine Cellar, 2 Pack

they work awesome batteries last almost a year I've seen people on here saying that they only last 3 months but that's not right the batteries that were in it lasted for more than 8 months they seem to hold accuracy quite well I calibrate them with a very high quality humidity and temperature gauge and they seem to be accurate over a long period of time. The ability to I have an app that tells you your VPD at any point in time is priceless and invaluable in a greenhouse

Works as advertised. Wish it worked with apple Home

Bought 8 months ago, one of these stopped working, I opened a ticket directly inside the app, they IMMEDIATLY sent a replacement device the same day and reveived it in 48 hours. The easiest and fastest problem solving I had with a custome service. So far I realy love the quality of theses (app and devices, material quality). Will look forward for more of their products.

Easy to set up.

Installed one of these at my mother's retirement suite so next time we'll know if her air conditioning breaks down. Integrates smoothly with Google home and was straightforward to configure. You can set min and max temperatures outside of which it will notify you. Should probably write "Wi-Fi thermometer" on it because it looks like a big Chiclet and gives no hint of its purpose.
