Review: works good - I use these to monitor the water temperatures on my boiler remotely and they work good and are easy to setup if you use the bluetooth on your phone for setup and have decent wifi for the data connection(tuya app)
Review: Simple IOT device that permits remote temperature monitoring using WiFi - I needed a device that would allow me to remotely check on the temperature of a refrigerator. I can get real time readouts as needed, and set alarm points if desired. It contains a battery, but I'm not sure how long the device would run on that battery. You can of course attach it to a 5 volt USB charger and that will keep it going indefinitely, using the internal battery to cover a power failure.

### ⭐⭐⭐⭐⭐ Simple IOT device that permits remote temperature monitoring using WiFi

### ⭐ Unreliable
*by C***. on November 7, 2023*

Pros Plugs in, no batteries needed. Magnets work well Display is easy to read Cons Not accurate, both sensors off by over 5 degrees (too high). Unreliable. Both sensors routinely have 15+ degree swings, setting off the alarms. Connection is unreliable. Constant disconnects and or shoring as offline. On/off switch is recessed so not easy to turn on or off. Annoying when alarm is going off due to incorrect temperature read. Sensor cord is so large it causes gap in freezer seal. Does not come with wall plug adapters.
