- Please remove both batteries for 5 seconds, then place them back in to the sensor.
- When you put batteries back in, you should see the sensor light up like this
- When you see the light, reset the app or refresh your browser and you should see the sensor back online within a few minutes
If the sensor does not light up, the batteries are dead. Outdoor sensors take CR-123 batteries, and the batteries should last 3-6 months depending on connection quality and weather. Extreme weather and temperature swings exceeding 40 degrees in the same day can drain batteries faster. Batteries will die sooner when disconnected as they do work hard to get back online. Once they have been offline for more than 2 weeks, the batteries will likely be dead. CR-123 batteries are available at most grocery stores, drug stores and hardware stores.
