Change of batteries

Check battery power by short press of the push button on the rear side of the device to activate the LED or check the battery power on gateway web UI:

The batteries are almost empty if LED is red and keeps fast flashing (100 ms on / 100 ms off) for 8 s and must be replaced within 2 weeks.

For optimal performance, we recommend using high performance alkaline batteries.


Communication between sensor and gateway becomes unstable when battery power is low.

Software update

Do not power off the device while updating. Do not update when battery is low, as device damage or data loss may occur.
