What is Honeywell RedLink? and Exploring the New RedLink 3.0

What is Honeywell Redlink?

Honeywell’s RedLink technology is a wireless communication protocol designed to connect thermostats, sensors and other HVAC accessories without needing traditional wiring. RedLink allows compatible devices to communicate over a dedicated wireless network. This means you can place thermostats and remote sensors where they make the most sense for measuring comfort instead of where wiring happens to exist.

RedLink works by creating a network in which devices like thermostats, temperature/humidity sensors, occupancy sensors and interface modules send and receive signals over radio frequencies. Adding a RedLink Internet Gateway to the system and connected to the home’s wireless network adds integration with Honeywell’s mobile apps so homeowners can adjust settings, check system status or receive alerts remotely.

Honeywell has released multiple versions of RedLink over the last few years. The earliest versions were focused on basic wireless links between thermostats and HVAC equipment. Accessories like wireless outdoor sensors and portable comfort control devices expanded what the system could do by letting the HVAC system sense conditions in different parts of the home.

Redlink 3.0

The latest version, recently released, is RedLink 3.0. RedLink 3.0 enhances the communication protocol with improved reliability, extended range and support for a new wave of Honeywell wireless sensors that measure temperature, humidity and occupancy/motion. These sensors send data back to the thermostat so that the HVAC system can address hot and cold spots more effectively, promoting a more balanced comfort throughout the home. RedLink 3.0 also works with modern thermostat models that come with built‑in Wi‑Fi and connectivity with popular smart home platforms such as Apple HomeKit, Google Assistant and Amazon Alexa.

RedLink 3.0 devices are not backwards compatible with older RedLink versions. This means that a new thermostat designed for RedLink 3.0 typically will not communicate with older sensors or modules that were designed for earlier RedLink versions. Likewise, older RedLink products will usually only communicate with other devices from that same earlier version.
