Is there a way to modify ADT's Window and/or thin Door sensors in some way to work as door sensors for Ring's Home Security System?
I am transitioning from an ADT security system to Ring's, but am not keen on buying Ring's door sensors for $20 each to replace ADT's.
This should be one of the sensors (by visual): Door. (I will update if I find the other sensor.)
(This SE:IoT question was similar, but is for the Samsung SmartThings. The problem was that the sensor used 345 MHz - incompatible.)
(Also asking on SE:HomeAutomation - I am not sure which forum is most relevant.)
