I have a magnetic door lock that I would like to make smart.
The way the lock works: on power -> magnet works, no power -> magnet release.
What z-wave/zigbee device can I install to cut the power between the battery and the lock as you can see in the picture below (marked in red):
Thanks in advance for the advice.
FYI, my end goal: Give unlock command to Google via watch -> send unlock command via IFTTT to Homey -> start flow to unlock device ???
