Good point. Yes, I currently have my router, access point and FiOS ONT all on backups, so theoretically the network remains up for a while after a power failure.
I just checked my Twine which is currently powered via a USB charger and has a fresh set of AAAs, and the voltage is 2.76V, so in my case at least it seems tough to tell whether it's running on power or on batteries. It would be nice if that could …
Are you using the mag switch, or just the built in orientation sensor (presumably with the Twine attached to the mailbox door)? I'd be worried about someone running off with my Twine if I left it in the mailbox!
I think I remember seeing this sensor when I was looking for one, but didn't see it sold as cheaply as in your link. I assume this would still require a pull-up resistor between power and input on the breakout, so the input's not floating, but it's…
I was wondering the same thing. My Twine is still reporting status at much more frequent intervals, but when I save rules I often see a huge wait time (a whopping 114 minutes when I tried it just now). For an Internet-connected device it seems a s…
Right - 3.3v power from the breakout board to the power input on the current sensor, and then hooked up the Input and Ground on the breakout to the corresponding connections on the current sensor. The sensor is normally open, and closes when it det…
No difference - I'm currently getting email alerts successfully. I just find it amusing that my sump pump could be posting to Twitter, that's the main reason, plus the fact that with it on Twitter it will be easy to review an event history.
The AC…
