I've bought several of these over the years and use them with my Hubitat to monitor various parts of the house. Reliable and simple to use.

One of the most reliable IOT device I have ever purchased. I have used abt 15 sensors of all kind for years with hardly any downtime or malfunction. Keep it up !

Wireless Sensor Tag (13-bit Temperature and Humidity) -- I use this as an open/close sensor. Love the predictable accuracy and long wireless range.

I've used WT sensors for a long time. Various experiences. - I have 4 general temp / humidity units with receivers. Three are in homes I live in. I just bought a fourth for a little computer equipment room. These are USB format. I originally bought backup batteries. These failed in a few years. The basic unit is terrific. The battery not. - I've used many "tile" format temp / humidity sensors that I place in fridge and freezer units. Mostly these work well when I can get a signal to the receiver. Batteries have to be changed. I'm not good at that. When the batteries run out and I forget to replace the unit I throw it away - not perfect - I use "tile" format water sensors. There are very good. Same battery issue. - I like the cloud server - lots of data retention and good displays. - shipping and service is good. The design / aesthetics of the product is superior. They're very persistent about getting buyers to provide a review - bordering on annoying.

I've used wireless tags for over 10 years and currently have 8 sensors for monitoring the environment of my home, both inside and out. I find them incredibly accurate, easy to use, and with a battery life of 3 months or more even though they update every 5 minutes.
