New to SmartThings.
I have a device (similar to house alarm system) that has, as output, a normally opened relay connection. Upon triggering, the relay closes and the output is “shorted/closed”. When no longer triggered, the relay opens and the output is “opened” again.
I would like to monitor this device’s output with my SmartThings Hub. So basically, I want a SmartThings compatible device that will take two wires as input and be able to tell me whether the input is “opened” or “closed”
I’ve found several posts about using arduino. Are there any plug and play products that will meet my needs? Also, something not too expensive would be nice.
