!EU Z-WAVE FREQUENCY! 868.42 MHz! Requires three AA battery.

No retail packing/manual (no corrosion in battery compartment or yellowed plastic, but small & light scratches on housing). This is from a finished smart homes for elderly residents study/trial. I have up to three of these for sale, message me for better price per units.

I have confirmed its functionality with a Samsung SmartThings hub v2 (reports the device's Z-wave version being out-of-date and potentially unsecure, but as a sensor, it shouldn't matter for domestic usage).
