WWV
I guess if your in a an underground bunker that might be an issue with RF reception but my WWV clocks work fine in the middle of nowhere. Maybe WWV is only a US thing. Not sure, and too lazy to check.
I would love to hook one of these things up but I can't figure out a need or want.
Yeah, I'm pretty sure I have a clock with this, and it seems to take about three days past DST to actually change the time.
Besides, that's a pretty weak argument. "Don't put this thing in that can do a bunch of stuff because here's another technology that's also not in any of these products that does only one thing."
Anyway, I'm already an Electric Imp fan. If I had the know-how to install these into things I already own, I would. Hopefully it'll catch on with manufacturers, and I especially hope it gets picked up by someone who puts it in a Z-Wave controller, so I can finally have some decent interaction with my house lights...
