I just noticed this in the warranty information

I am not a lawyer, but on first glance that looks like using HA might be grounds for a warranty claim refusal?

It was a while back but went through all this before. here
Givenergy have some "Approved" apps that they allow with no warranty implications, although it's not published anywhere which is a bit of an oversight.
I believe approved it currently runs to:
GivTCP (both standalone or HA flavour)
Givenergy_Modbus Library (and presumably anything else that runs on top of that although it's getting out of date now with new Firmwares. A forked version appears to be being used in GivTCP latest to talk to AIO and so on)
Richard's "Inverter" App (the BBC Basic one > https://apps.apple.com/gb/app/inverter/id6443976497 )
Presumably @Rubikcube 's Inverter Monitor (as it's read only anyway)
However none of those are Givenergy "in house" work (GivTCP presumably get's quite a bit of inside assistance) but if something were to go wrong and roast 1,000's of inverters somehow (so many FW's and registers to consider now), I'm not sure if the stance would change?

Tim and thus the warranty needs wording more clearly (specifically along the lines of "unapproved LOCAL control") I'd imagine. BUT that comes at the price of keeping an upto date list of approved software as well.
Using anything that uses the API at all would seemingly void it as it's written even though GE go to great lengths to stress the tie up with Octopus to the point of actually basing several tariffs around it.

Zakalwe I don't recall seeing many (any) claims being refused to date (barring terrible installation methods or installers fitting too many panels to a PV string) so I'd say they are pretty good at not trying to weasel out. The "Special" E.on battery Firmware thing would be something they may need to deal with down the line so I guess there is a chance things may get a little more strict as years go on but for now i think the sheer volume of installs means it's quicker/cheaper to roll over and supply a new one rather than waste hours trying to play blame game to get out of it.
As worded, landlords installing for tenants could be breaking all 4 clauses of the highlighted sentence.
