My UK electricity provider Octopus Energy are providing ad-hoc free energy periods. These are typically only notified a day in advance. So the game is to store/use as much electricity during that period as you can. https://octopus.energy/power-ups/ If you are in the East of England area I would recommend signing up, nothing to lose!
I have a schedule set for my usual Octopus GO cheap rate tariff, but don't see an obvious way to temporarily enable battery charging other than to add a temporary charge schedule via:
Settings->ess->scheduled charge levels
Is there any other way? I can imagine this being a useful manual control, for example if you were in a mobile setup and want to immediately add charge when you dock/park, or if you knew of an impending power cut...
Thanks, Paul.
