So the backup only saves the most recent 100 events to the backup file AND the device database is also purged?
This makes me think that I have "misunderestimated" estimated something, as the purge will drop the last hours in the day of anything reported or polled at an interval greater than 15 mins. So, weather, power, water, and motion are going to be truncated in the backups, unless there is some way to separately backup the WHOLE event database as a stand-alone file.
The problem with "motion" is that vegetation waving in the breeze, feral cats, birds visiting the feeders, and even the rippling of the pool surface can set of motion detectors. It is hard to get a "minimum motion" defined for the few that allow such settings.
Weather data I can get elsewhere, of course. Just a shame I can't monitor it with a purported "central home automation hub". Its no longer the core device, I guess a Raspberry PI or something with an attached NAS drive will have to become the true "core", and the Hubitat a mere peripheral.
Power, and water are obvious - less resolution means that I don't see a familiar "heartbeat" with the little spike at the start of every fridge cycle (the starting current of a motor is always higher than the running current) to show that it is the fridge, I just see a spike of so many watts. I end up with peaks and square waves.
With water... is the toilet leaking every time it flushes, or are the groundskeepers just doing a far better job of washing their hands after using the toilet in these days of pestilence? At 15-min intervals, I'll never know unless I get lucky, and the water leaking his a leak sensor before it does damage.
Almost not even worth the very high cost of the devices to monitor consumption if the data is just going to get dropped on the floor at any decent resolution.
So, I am not just flying blind during the maintenance window, I have amnesia for any event that would be hidden in the noise at a 15-minute interval, or I loose all data collected for some interval before the nightly 2am purge.
I'm going to have to think about this - when I was a postdoc TA, I had to teach the Nyquist–Shannon sampling theorem, so I kinda think I have a problem here. ![:wink: :wink:](https://community.hubitat.com/images/emoji/apple/wink.png?v=12)
