There is No LED Activity and My ZSE40 4-in-1 Sensor is Unresponsive
print icon

This is product is discontinued and replaced with ZSE11.

What does that mean?

Once the battery is inserted, the ZSE40 4-in-1 Sensor's LED indicator should flash any time you press the Z-Wave button.  

If you insert the battery and see no LED activity whatsoever, first check that the battery is inserted and oriented properly. It may just take this small adjustment to get the sensor up and running.

 

If you find the sensor is still unresponsive after double checking the battery, try the device with a fresh battery if you have one on hand. If the device works fine with a new battery, the issue was probably caused by a drained battery. 

 

But let's say that the sensor shows some LED activity but is unresponsive in other ways - maybe you're unable to wake it up, include, or exclude it from your system. This calls for factory reset, which is a hard reset that will erase all previous activity and custom rules from the device. Here's how to reset your 4-in-1 Sensor.

 

If the sensor is still unresponsive after trying the suggestions above, please let us know! Our team will be happy to help.
