Eco Mode not charging overnight

For the last two nights (30th and 31st) my batteries have not been charged overnight. I'm in eco-mode solar+grid, and they usually charge to 60% overnight. Has there been a change in the eco-mode automations?

And I can see that the atomation hasn't changed anything since it set the afternoon charge period on 29th Aug. Is it failing to connect?

ianp has your API key expired?

Isn't this the GivEnergy server controlling my inverters and batteries? Do I need to supply givenergy with an api key?
