As the ToU software is at last becoming available I thought it would be useful to get some feedback on the functionality offered. My biggest issue is that control of grid charging is only offered in an automatic mode controlled by an algorithm. That algorithm has no view on the weather or the users demand the next day. There is no ability to manually select the amount of overnight charge required. I see that some users are using the Backup facility to force a grid charge but this is not available in the UK. For me the lack of a 'manual' option is a key issue in ToU and could significantly impact the payback of the Powerwall. I'd be interested in others thoughts on this.
