I have a fan control rule that uses a comparison between an indoor and outdoor sensor's (Inovelli 4-in-1 device) temperature reading to decide if the fan should run. I'd like to add a check to see if one of these sensors has disappeared, maybe the battery is dead or the wireless connection is lost. Hubitat tends to keep a sensor's last reading recorded as "the" reading. My thinking is I could look at
lastActivity to see if it's been a while since it last checked in, but maybe that's only for motion.
What I'd like to know is if its been >12 hours since I've recorded anything from a particular sensor and if so, pause the rule.
