List of sensors tested with WeatherRelay as of 07 June 2024.
Currently sensors from LaCrosse, Ambient Weather, Ecowitt and Logia are supported.
Additional sensors from these and other brands may also be compatible.
Note that Ecowitt devices transmit the same packets on 915Mhz, 868Mhz and 433Mhz.
The most recently added sensors are indicated with an asterisk *
Except where indicated, all sensors are 915 Mhz.
