I noticed the response to the change you made about 10:30 last evening. Obviously the change isn’t correct. Did you try the Consumption setting?
I would suggest that you remove the secondary device settings all together or reset them to what they were before. From the display the resulting graph is completely wrong. The consumption is now appearing to be twice that of the production. It looks like Bankstownbloke should be able to resolve the issue.
I looked up this device and it has settings…see page 24 for function settings:
Your installer should be able to set it up properly if they know how to do that.
