App issues

I'm a new (naive) user - Octopus Solar Battery installation and GivEnergy monitoring via App. v. 3.4.4
Realtime Dashboard was fine, but now...

1. No flow to or from the grid.
2. Home consumption understated.
3. The only flow is between panels, battery & home.
   Re installed App. No effect.
   Can't get through to GivEnergy support.
   Is there anything I can do directly?
   Anything similar happened to others?

Mikebmbcs Your first point of contact should be Octopus, not GE.

I'm afraid you haven't given enough info about what you have for anyone to really comment.

Have you tried the GivEnergy dashboard? When you say app, I presume you mean on a phone.

2. Home consumption understated - what do you mean. Power or energy consumed?
3. If you are on Eco the inverter controls will try and minimize any flow from grid and it will put back any excess solar into the batteries to use as needed to minimize grid import

Mikebmbcs If it's a recent install, your first port of call should be your installer, Octopus. (Their aftercare is pretty good...)

The home consumption is inferred based on what the inverter is doing and the grid activity it measures. The latter is done through a CT clamp around one of the meter tails. It's worth checking that that's securely fastened.

This is my system, showing two CT clamps: one top-left, and one near the middle.

I think the signal wires can also become detached at the other end, but that's slightly more technical.
