Grid Failure alarm does not reset properly after grid restoration

I have enabled Grid Failure alarm on the Venus GX coupled to a Multiplus. When Grid failure occurred I immediately got a notification email. When Grid was re-established I also received the VRM Notifiier email which said Grid Lost has changed to Grid Established . All good. 12 hrs later grid failed again but I never received the notification. Other parameters which I have setup to inform me when grid fails such as " no input AC " did work and I got the notification. When looking at the Alarm Logs on the VRM Portal it does not even show that there was a grid failure at the second occurrence. During the second grid failure period I looked at the Remote console and there was a Grid Failure alarm flashing . So it seems one has to acknowledge a Grid failure alarm before it will retrigger a second alarm even after the alarm has cleared . Seems like the Grid Failure algorithm needs to be looked at .

It seems to be working now !. Had two grid failures today and received notifications for both.

It looks like the fix has been pushed into the latest beta, and will be in the next release version 2.60

You are able to try the fix now if you are able to load the beta, and feedback would be appreciated in that beta post. Usual beta testing rules apply - read them over there for more warnings.

I am also having this problem.

Enabled the grid failure alarm on the GX (Octo) . It triggered and sent alarm to VRM ok. I cleared it on the GX, but it never clears on VRM.

I've disabled the alarm on the GX . .have rebooted it.. and it simply wont clear from VRM .

something to do with settings on the VRM site pages.. I had alarm settings on.. but no rules set.. I disabled this...clears the faults.. Conclusion? If using VRM .. do all the alarm setting there and leave well enough alone on the GX.
