1. Two visits of the electrician were needed because the house fuse needed to be upgraded. Should have been identified before first electrician turned up. 2. The overnight charging schedule doesn't work reliably and sometimes the car is not charged in the morning (not good). Have had to reboot the unit several times. Your technical help people say it is because the unit loses its connection ? Whatever the reason it needs fixing as the charging schedule is critical. 3. The app is not great. Didn't accept my password for a long time, had to make several calls to resolve. App stopped working on my wife's Apple phone.
