By leveraging an existing Wi-Fi network, the innovative sensor communicates with a building management system.

As Wi-Fi technology evolves to become cheaper, more reliable, and more secure, we’ve noticed that many of our customers are using Wi-Fi to power their networks. We wanted to provide a sensor with RLE’s quality and reliability that could quickly and easily integrate into these environments.

Jeremy Swanner, President of RLE Technologies, agrees, “over the past two years, RLE’s wireless sensors have set the benchmark for affordability, battery life, transmission range, and integration. Going into this project we knew the WIFI-TH would have to meet the same criteria, and it absolutely does.”

The new WIFI-TH is wireless and powered by batteries. Since wires are not needed for transmission or power, electricians are no longer required for installation. In addition, the Wi-Fi sensors from RLE Technologies are unobtrusive, compact, and offer an industry-leading battery life—around seven years at a transmission interval of five minutes.

The humidity and temperature data of the WIFI-TH can either be pulled into RLE’s WiNG-MGR or transmitted through a UDP packet to a BMS system. While IT departments may not be keen to add wireless devices, they can be rest assured that these unique sensors were developed with security in mind.


  • Only enables one-way communications, which means there is no risk of hacking them remotely
  • Includes encrypted data storage for configuration and network information
  • Completely supports industry-standard WPA/WPA2‑PSK encryption

Facilities all over the world are utilizing RLE Technologies’ WIFI-TH to observe variations in humidity and temperature, maintain optimal equipment performance, fulfill efficiency goals, prevent downtime, and anticipate equipment failures. The new WIFI-TH sensor is in stock and ready to ship.
