I haven't got around to doing a controlled power failure test but I was at home today when we had a 45 min power outage so I did some checks during that power outage:
During the full power failure, my network switch and wifi were on UPS now so I eventually (*see below) got Comfigurator on my laptop to show the GSM4 UCM GSM network signal status. It showed "Good - 3" as the network strength but I had NOT received a power fail SMS text message.
When the AC power returned after ~45 mins, a few minutes later I did then receive a Power restore SMS message. Also, when the AC was restored I then immediately checked the signal strength again and it showed "Fair - 2" and texts are working normally. I never miss one under normal circumstances.
So, I'd say this seems to show that the fault is very likely with Comfort. I can still do a controlled test power failure (i.e. Comfort main panel only) if needed, but the fact that the GSM module claimed to have a good signal strength does point a Comfort bug somewhere.
* I think there is a minor Comfigurator bug/quirk - if you launch and open the config, navigate to the relevant GSM4 Module and click "Get Status", it asks you for the PIN to login, but then does not immediately show the status. Trying again now I think it puts you on to a different page and you have to navigate back to that page, but maybe I did not notice that earlier during the power failure.
Also, when I was in power fail situation, the "GSM Network Strength..." message appeared in red for a couple of seconds and was then replaced by "Normal/No error" in black and no mater how long I waited the signal strength message didn't reappear without me navigating away from the module and back again. Now I'm in AC-okay mode, it still does mostly stay on "Normal/No error" but does regularly (every 30 seconds or more?) switch to the signal status message, but still only for a couple of seconds. Not
