What happens to HA (Home automation) if the Internet is down?

(1/3) > >>

Mic_:
Question; what happened to ones ability to interact with Home automation if the home Internet (IP Provider) goes down? Is there any work-around known, if one is away from home (Happened recently) and the home internet link goes down? Cell phone service, being independent, was not impacted. strange to be out there and cut off.


The question is, is there remote HA interaction without the internet?

SkipWX10:
I recently went on a three week trip...normally I would just leave the CM15a in charge, but if we had a power outage, there would have been no way to reset the clock. This would normally have been 'internet independent' and the CM15a runs my house and has done for over 13 years (in this house)

This time, though, I decided to try the WM100 and set it up to take the CM15a....I would be able to log into the app after an outage and re-sync the time and all would be well. This, of course, IS 'internet dependent' but had ability to 'recover' if power or the internet went down for a bit.

I know this doesn't answer you question other than 'you can use the CM15a independent of the internet' and doean't account for lots of other HA tasks...

Unless you just want individual control of specific things via a dial in touch tone controller, the short answer is 'no.'

 If there were likely to be an extended internet outage one could always install a cellular data modem and pay for a data plan but that's probably overkill.  If a power failure and extended internet outage causes a device to lose it's time, a battery backup might solve it or switching to a device with a real time clock with on board battery would work.

I use a controller with an onboard coin cell to backup the clock so without internet everything in the house will function normally as happened during Hurricane Irma when we had generator power but no internet for 10 days.

I (still) have an ancient Leviton DEC Telephone Transponder, catalog number 6325. Call your home phone (landline) and the 6325 seizes the line after the answer machine picks up. You can control all 256 X10 codes by doing a tap dance on your phone keypad (DTMF tones required). You carry a little card with numerical codes for House Code and Unit Code so you will always know, wherever you are in the world, how to turn on your hot tub...in 1988.
I see brobin gave you the "short answer" in his response. This is the long one.  rofl

I had one of those too and I impressed my date one night by doing exactly as you suggest - turning on the hot tub while driving home from dinner.  That was when a mobile phone was the size of a desk phone with a shoebox sized radio in the trunk and a little pigtail antenna stuck to the rear window.  She was so impressed that 35 years later she's still here!  :'  :)% rofl
