Octopus R&D Integrations

Asking here, as I can't find a forum for Octopus R&D.
I've signed up to Octopus R&D, and have got the app on my Android phone and can log in to R&D on a computer too.

Under 'Integrations' (on the app only, not available on the web page), it says 'no integrations'.

How do I set up an integration to my GivEnergy inverter? Does this occur automatically (somehow), or do I need to do something to instigate it?

I'm currently on a Flexible Octopus tariff, but have an application for a SEG in progress, and want to be able to remotely control/schedule my inverter while we're away over the summer.

James L When I created an R&D account it was missing lots of bits for a few days, then the ability to add devices just appeared. I understand this is what normally happens.
