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.

Use wireless tags for remotely measuring temperature in the house and refrigerator. Use for many years and very satisfied.

Very sophisticated and well-thought products that would sell more readily if some of the information and instructions were in more common language geared for the non-techies in the world.
