If anyone watched the big announcement from Octopus, their new in-house batteries are actually just Fox systems with a pink faceplate added.
The Nook is the Fox ESS MiniQube AKA the Avocado S22, and the Octopus Nook Colossus is just the Fox Evo (which Octopus already supply anyway).

What I am wondering is if they'll work in the Fox app, or if that's been locked out. Pricing sounds like it'll be about the same as Fox's.
