What do the LED lights mean on my water heater sensor?

The LEDs can tell you a lot about your sensor and where to start troubleshooting if you notice anything wrong. If you see a different colored light or pattern that is not in this document, please reach out to us to troubleshoot together. Please note: The sensors were designed to conserve as much energy as possible. The LEDs on your sensors may not be on unless that sensor is woken up by the Hub.
