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: Good device that isn't battery operated - I bought this one because it plugs into power instead of having to replace batteries, and it has proven to be a great device. The cord is a bit larger than I would like to go through the seal on the freezer but it doesn't seem to bother it.

## Customer Reviews

### ⭐⭐⭐⭐⭐ works good
*by G***B on December 15, 2025*

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)

### ⭐⭐⭐⭐⭐ Good device that isn't battery operated
*by R***O on October 19, 2025*

I bought this one because it plugs into power instead of having to replace batteries, and it has proven to be a great device. The cord is a bit larger than I would like to go through the seal on the freezer but it doesn't seem to bother it.

### ⭐ 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.
