Hi SSP. You may have an 'Alarm Rule' inadvertently set in VRM. Seems related to your AC IN coming on. Don't worry about minor sampling time discrepancies.

In VRM, go 'Settings' > 'Alarm rules' to see what's armed. If it's sending you unwanted emails you can turn that off too.

Hopefully it's that simple, but come back..

I think your right....the system was set to raise an alarm on pass through.....would it be the case that no current is detected on the VE Bus when the system is in this state?

Seems you've found it, great..

I imagine the alarms are generated at the VRM end, and VRM can surely see 'Passthru' in the data sent. How it's determined at the local end I dunno. Perhaps when that big transfer switch inside goes 'CLUNK'. Yes, you can hear it.. :)
