What to do if Cotech Weather Station wireless sensors are not transmitting data?
- RRachel NguyenJul 25, 2025
If your Cotech Weather Station's wireless sensors aren't transmitting data, and the display shows “--.-”, try the following: * Press and hold [ CHANNEL/+ ] for 3 seconds, then select the sensor to reconnect using [ CHANNEL/+ ] or [ HISTORY/? ], and confirm with [ MODE/SET ]. * Ensure the sensors are between 1.5 m and 30 m from the indoor unit. * Try placing the sensors higher up. * Check that the sensors’ displays are working or LED indicators are flashing every 60 seconds. * Insert new batteries into the sensors, using lithium batteries in cold climates. * Check the batteries in the indoor unit. * Ensure the radio signal isn't interfered with by metal constructions. * Move the indoor unit away from other electronic devices like routers, computers, and televisions.
