Wyze Sense Modification Idea

I have an idea to use the Sense to monitor the status of appliances such as an air conditioner, furnace, refrigerator, sump-pump etc. If the magnetic reed switch were replaced with a pair of wires connecting to a current sensing relay such as [This](Veris,Current Switch,Mini Split-Core,Fixed,N.O, H600 Amazon.com) it should provide an on/off status.
