I searched for SmartESS PV undervoltage alarm and got nothing so...

Down once again - 3rd day in a row
Sad - it's been running so smooth for the past 4 months ...
SA starting to look more and more interesting.

Now it is telling me that it is offline. I have all the lights on the dongle so I am guessing that this is yet another problem on their end?

There was a 15 minute breakdown at 17.50 CET - but since then no hickups

Yup, this time it resumed fine and no downtime. I've also emailed the company to know if they were doing some maintenance (I'm was just curious), and they put a banner on the app (before the login), informing about the maintenance:

Our server will be expansion and maintained from 10:00 to 16:00 GTM 2024-02-18. During the period system access may be affected

But since yesterday it's working fine and all the alarms were cleared. Hopefully it will last, I never had such issue during the past year.
