As of 1 February 2026 Battery Boost is no longer available. We’ve contacted all customers who have been impacted by this change. 

 

Depends on the individual system. You may only have data for power in and out of the battery. You will need to take into account conversion efficiencies, battery losses, VA errors and instrumentation accuracies in each direction to be able to reconcile the figures. The only data considered valid by OVO is what is measured by the smart meter. You can read about meter accuracy in the link.

If OVO isn’t getting the data, then chances are neither is Kaluza (which is OVO’s sister company). That almost always means the root cause lies upstream from Kaluza, which likely explains why the Solar Team suggested contacting Giv Energy.

They’re the ones who can see what’s being sent out via their API. I’ve known multiple EV manufacturers cough, cough Hyundai/Kia have a terrible system that spits out almost garbage data to Enode on a regular basis, which knocks out basically every Smart Charging setup in Europe…

The problems aren’t always as obvious as they first seem I’m afraid. Just because the first-party tools appear to be working fine, doesn’t mean the API for third-party tools is also working properly - they’re almost always two separate “things” so to speak and one can easily go offline without affecting the other.

Pretty much the only service I know of that has both users using the first party official app/client and third-party tools/bots/scripts from external developers use the exact same API is Discord because that’s basically just how they built it… Which also means if the API goes down, it knocks out everyone and everything at once.
