Having recently installed solar PV and a hot water diverter system at home I’ve been testing the MySolar Divert App developed by @mattjgalloway. It looks really great however I’m having some issues getting it to work correctly. Has anyone else successfully used My Solar PV divert?
MySolar PV app is working correct, the diverted energy is included in the ‘use’
The two main issues seem to be that the diverted power is not shown on the graph even though it’s shown on the tool tip and the house use is displayed negative on the tooltip even though the house use feed is never negative (see multi graph above).
IIRC the app takes a total “use” ie divert + other use as a single value, then removes the divert for “rest of house” so if you are supplying them separately eg 200w use and 700w divert, that makes 200-700= -500 “rest of house” use. Whereas 900w “total” use would be 900-700= 200 “rest of house” use.
@pb66 is right. The “use” feed needs to be the total use and the divert is what of that is diverted. It’s done that way to be most consistent with the other solar PV app.
What do you think about modifying the wording of “House Use” to be “Total Use (Including Diversion)”? I’m sure I’m not the only one to have fallen foul to this misunderstanding.
I’ve just noticed the description for the app mentions a historical bar graph view, I can see any way to access such a view, does it exist? If not I can edit the app description to remove the mention:
Ah, interesting. That button seems to be missing from the current app. See screenshot. I’ll do some digging. This is probably due to the recent CSS changes connected to the new sidebar layout which is still in beta. I will ensure this is fixed before the sidebar changes are merged.
On what I hope is a related subject of setup, is it possible to use virtual feeds in the latest version? The reason for the enquiry is that I have feeds for the divert and for the rest of the house but not the required combined ‘total power’, so I have created it using virtual feeds. However, the app does not present the virtual feeds in the drop-down selector.
