What to do if the wireless sensor of my Cotech Weather Station sends no data?
- CCrystal WilliamsAug 11, 2025
If the wireless sensor isn't sending data to the indoor unit of your Cotech Weather Station, and “--.-” is displayed, there are several things to try: * Remove the batteries, wait a short time, and then reinsert them. * Insert new, high-quality alkaline batteries into the sensor. * Manually scan for the sensor by holding the [ ? ] button for 3 seconds (note this will erase the rain sensor history). * Ensure the sensor and indoor unit are within the 1.5–30 m range. * Check for signal disruptions caused by nearby metal structures. * Move the indoor unit away from electronic devices like routers, computers, and TVs. The cause of this problem might be that the indoor unit isn't receiving a signal from the rain sensor within 3 minutes.
