keeping track of power cuts ...
we're prone to power cuts, and one on Sunday ran longer than our UPS could last ...
meaning Cortex Histories cover only part of it ...
IDRANet was kept going longer by our IPSs, but that doesn't help !
so, wondered if anyone has a way of timing power-cuts - in olden times, a simple electric clock would have paused for the duration, meaning its display would have revealed how long ...
nearest we have to that is a mechanical time-switch, but it's not easy to read it precisely ...
this sort of thing :

in any case, how would we arrange the reading as an input to Cortex ?
corrections to Window's time come from the 'net, without which drift would be a problem ...
we're not using Reflex, yet ...
any ideas ... ???

If you have a smart ups, there is usually monitoring software that can track interruptions. Won't feed back to Cortex though. Some mid-level UPS have USB connections to tell windows to shutdown, you might be able to also send an email or log to disk on power interruption, and then get Cortex to send an email when it comes back up. That may be a reasonable indication of duration, though not exactly what you asked for. Or, if you monitor a power meter, it would go to 0 consumption and probably be logged in Cortex history before the UPS gave out. Then can see history starting again when power comes back on and Cortex presumably restarts.

thanks for replies, some food for thought !
did wonder if the MFP timers could be used in some way - as long as the IPSs keep IDRANet going ... but can't see a way !
AH's feature on Idratek / IoT / WebAPI published a bit over a week ago shows v.low-cost Android tablets are a display device option, so maybe linking to Tasker is also a possibility ...

yep, we know - from the Log generated by a QLD - when the power went down ... not sure why the other QLD & the SLDs didn’t do the same, presumably one’s enough ! Not the same, of course, as Cortex having a record of it, to add to it’s knowledge of when IDRANet started-up, and so calculate the interval to present to us directly ...
not a big deal, perhaps, but knowing the interval, we’d be able to size the extra batteries we need to add to keep the UPS running usefully longer !
Our experience, too, with Cortex, and HA generally, has been that the more data we have the better ... we tried to be cost-efficient, when we created our network, but we regret not including most of things we decided to omit ! Going back & adding sensors later, is quite painful & expensive, in time & money !
this time, our PC stayed down - we need to bottom why, which first means finding a time when we can power everything down, so we can take a look at BIOS settings !
