I have a closet with a line voltage jamb switch, so when the door is opened, closet light turns on.
Looking for a device (z wave or zigbee) to detect (for security purposes) the jamb switch closing the circuit.
Perhaps I can place a device into the j-box which needs to
- detect the (dry) circuit being closed by the jamb switch when the door is opened
- connect the line to the load (light)
Another possibility – is there a device which is wet contact sensor (would then leave the wiring as is - the jamb switch would close the circuit and the device would detect that)?
