Has anyone figured out how to create an alert based on a devices (actually all of my water sensors) last activity after a set period?
See attached, I have HSM notify me when battery device statuses drop below 25%. This works well, accept that lithium batteries (from my reading) and there percentages aren't exact and always predictable. I have a device that I think dropped off a while ago.
I think this is why I maybe didn't get a notification as the battery in hubitat still reads 37%. Of course I could adjust the threshold from 25% up, but I'd like another redundancy for a device check in. Ideally a rule that looked at last activity over all the water sensors and let me set the time between a check in and what the rule is looking for.
The rule would say if no check in from device after 3 days from last activity notify my phone.
Thanks in advance.
