Ability to use Twine as a power sensor when running on USB-supplied power
I use my Twine with a USB power adapter and batteries as a backup. It would be nice if the presence of USB power could be added as another sensor rule - when USB power turns off/on then send email/text/etc - so Twine also acts as a power sensor. I'm using my Twine to monitor electrical equipment via the breakout board and an AC current sensor, and that equipment is never going to run in the event of a power failure so it would be great to get an alert when that happens, or build that condition into other rules.
You might check your UPS for a similar option.
The USB power may be unrelated to the WiFi power, or the user may be on a WiFi ISP or corporate (campus) scenario.
That said, I'd also like a mail notice when XX minutes/hours have gone by without a report. Nexia does this.
The report page already says when the device is on external power. Making that a rule trigger should be easy.
I just need to know if power is out in the winter primarily so that I can deal with things freezing, knowing temp drops is good but when I stop getting alerts I won't know if all is good (I can look at a webcam but would like proactive notification) or there isn't power.
Alternatively, if anyone has advice on a UPS with some alerting software that works with a Mac I could use that info too.
Would love to have feedback from the SM folks if you think this is likely to come our way or not.
