I want to connect a loop of existing security sensors from my previous alarm system to my Wyze security system. This would be easy with the v1 entry sensor that uses a magnetic reed switch (just remove reed switch and connect NC loop to the two contacts) but I can’t figure out how to do this with the v2 switch. Has anyone managed to do this? I can’t find a good source for the v1 sensors and would in any case rather use the newer sensors.
Replying to my own question.
Would the leak detector be usable to monitor a normally closed loop? Seems like it could monitor a normally open loop, so you might need a relay of some sort to switch states?
Replying again to my own question, I think I can wire a small electromagnet into an existing NC alarm loop from previous alarm system and use that to close V2 sensor. Any opening of alarm loop would turn off electromagnet and activate V2 sensor, setting off alarm. Loop and magnet would be powered by low voltage wall wart, possibly attached to Wyze switch to energize only after Sense Hub changes from Disarmed to either Home or Away. Getting supplies to test. Any comments about this possible approach?
