SMS Trouble after power failure

[caravanboy]

Great, I\'ll look forward to a firmware update some time in the future. Thanks for investigating!

[caravanboy]

Any news on a firmware update for this yet?
I removed my custom AC failure messages. I had an AC power failure today but received no standard Comfort SMS messages whatsoever.
Comfort phoned me and I signed in (AC had already restored by this point), I can see those events in Event log and then a few minutes later I see it attempt to \"Dial\" other numbers, presumably to send standard SMS messages, and I see SMS Dial Failure #16 and #99, but I thought you said those were to be ignored? I then see SMS Trouble and SMS Restore a couple of mins later again, and a few more SMS related events after that too, but no actual texts. It just feels like something is still wrong with Comfort\'s logic/config here?

Can you send the actual event log after the power failures?
Dial failure means the message was sent to the mobile provider station but it was not delivered for some reasoncan you repeat the power failure test?

[font=\"Calibri\"][size=\"3\"]Hi, yes, sorry. Below are the actual event log entries. [/size][/font]
[font=\"Calibri\"][size=\"3\"] [/size][/font]
[font=\"Calibri\"][size=\"3\"]Please note that I later realised I had actually received two AC failure related SMS messages (not sure how I missed spotting them the other day), one for the failure, one for Restore. [/size][/font]

[/size][/font]
[font=\"Calibri\"][size=\"3\"]However, there is still something not right as both text messages were delayed by 5 minutes and did not arrive until 13:43, which seems to align with the repeated Dial Failures below. [/size][/font]
[font=\"Calibri\"][size=\"3\"] [/size][/font]
[font=\"Calibri\"][size=\"3\"]Yes, I can also try and simulate a power failure again if needed.[/size][/font]

As there are many SMS Trouble and Restore I would check the GSM signal strengthIt is shown in the left bottom in the UCM/GSM4 window The signal could be dropping out, so the SMS is sent when it recovers. We have a high gain antenna which improves the signal level

[caravanboy]

I\'ve looked at the signal in the past and it is always good.

My Comfort system regularly SMS messages throughout the day when it notifies me of gates opening & closing. I never have any issues with those messages, they\'re always received within 1-2 seconds, and there is also a back-up Gmail message (sent at the same time by a different system) so I\'d know if the Comfort SMS messages were ever delayed.

I only ever get issues with missing Comfort SMS message around power failures.

\"SMS Dial failure\" in the event log means that the UCM/GSM sent the message to the GSM network, but it failed to be accepted. The reason for this is not known.However Comfort will repeat the attempt 5 times until it gets an acknowledgement that it was accepted ie  \"Remote Signin - User # SMS Acknowledge\"
There were 3 rounds of attempts to phones 1 and 2 until the next try succeeded - that is why there was a 5 minute delay
I am not sure why this happens with power failure. We will do some testing

Hi, has there been any progress on investigations of this? I had another power failure last night and had similar problems.

I did receive a call from Comfort (via landline) but received no standard SMS AC Failure notifications.Power was off for ~35 mins. During this time I was unable to get any response from any SMS control messages that I sent and making a voice call to the GSM Module immediately cut off.  I DID receive an AC Restore SMS about 10 mins after power was restored.
I also noticed a new issue - when I made a call to Comfort\'s landline during the power outage it took about 25 rings before Comfort voicemail answered even though it is configured to answer after 8 rings. This is very odd and was as though Comfort was just too busy stuck with its CPU processing something else (maybe failing to send SMS, or GSM module issues?).
Also, I noticed that even 25 mins after AC power was restored I could still NOT get the Comfort GSM module to answer a voice call. I tried twice but it just immediately hung up after a single ring. I know the GSM modue was partly working though as it was now answering SMS messages again. 
I tried again a voice call to the GSM module couple of hours later and it was working normally again.
This is very annoying and I\'d really like Comfort to work correctly when there is a power failure. Do you have any ideas?

[slychiu]

Can you turn off your AC power, ie make a POWER  faiure
Check the status bar in the UCM/GSM Module screen .
\\It should show the GSM signal strength
what is the signal strength shown?
Turn in the power, and check what is the signal strength

[slychiu]

It is better totry the following.

with AC on,Get on the UCM/GSM modules tab ad check that the GSM signal strength on the bottom left status is normal ie 2 to 4
Turn off the AC and check what happens to the signal strenth on the status bar. does it disconnect and try to reconnect
wait for it to revonnect to the network. if it reconnects, try the sms and call in
Turn on the AC agaibn and checj what happens to the signal strength
