Does anyone know of a way to have a trigger when a device doesn't change? Clearly if it is an on or off device, it is easy to trigger based on it being on or off for a certain period. But what if one wants a trigger based on a device with an unknown value not changing from that value for a certain period of time.
I would use such a trigger to tell me if certain plug ins or devices are not working. For example, if a remote thermostat's battery is dying, the temperature may not update from 65. I would like an event that triggers if the thermostat value hasn't changed for 48 hours. But if that value is always changing, I'm not sure how to write the event.
