Pause charge control

During the winter months as the solar energy produced is so low, and the likely requirement for the storage batteries would be to force charge to maximum - it would be useful to pause the automated charging so that the Fox charge window can be left set to force charge the batteries.

For the winter months when a full battery charge is needed, it will then run from schedule which reduces the risk of them not being charged just in case the HA / Fox cloud / App / Wifi stops working (i’m thinking about the impact of possible power cuts)

ideally, it would operate as another switch ‘hold charge time updates’ - the forecast sensors and calculated kwh should still update but the setting of the inverter charge times would be suspended, allowing the default charge period to be set, and left in place until the winter months are over.

Edit: having thought about it a bit, its probably the programatic equivalent of latching on the ‘Force Charge’ switch
