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

I bought this device for our barn which has a WIFI router. The temperature is measured in 10-60 min intervals, depending on your settings. An alarm is sent to your phone and/or email address if the temp is outside of your chosen parameters. All is easy to set up. When the device is near your phone, it connects via bluetooth as well. All parameters can be adjusted this way. Once it's out of reach and connected to WIFI only, some parameters cannot be changed anymore (alert thresholds, network settings, calibration) which threw me off at first. You will need bluetooth connection for that. One tip: to change the batteries, the lid can be pried open and must be completely removed. If you force it open thinking there are hinges like a door you may break it.

So far (3 days) this temp sensor has been a delight. It was super easy to set up. The app download went fast. Be aware that this sensor requires 2.4GHz WiFi (does not support 5G). The app found my sensor and linked up quickly. It has been logging my fridge temp for the last 3 days. The apps is easy to use and makes sense.

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.

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
