I'm seeing a few work arounds for the MG BEV's due to the powers that be banning remote App access to European/UK cars due to data protection. One of the big bug bears was starting & stopping charging to take advantage of cheap overnight electricity rates usually between midnight & 05:00 hours.
A gadget from Shelly have come up with a good cheap alternative for a "dumb charger" like mine.

As I've mentioned I didn't go with the OLEV grant people because of the high price for a Smart charger even after the £350 OLEV grant.
Mine cost £163 & if I wanted to turn it into a smart charger it would be £9 more
This device which costs £9 will do the exact same job if you need to charge your car via mobile phone App at certain times to take advantage of overnight cheap rate electricity.
