Installation and planning was excellent, however. The unit works for manual charging but does not work for scheduled charging, I require the unit to make scheduled charges in relation to my British Gas EV tariff between 12:00-5:00, the unit and the chargemaster app do not provide accurate information, this is being looked into and chargemaster have identified a fault on the units that they are looking to fix. Key Issues No confidence when scheduled charging takes place as the data in the app is miles apart from reality, It has recorded my vehicle as charging for more than 24 hours when I was out at work all day. It has recorded negative duration's of charge periods, how? If they can sort out the software problems out this unit and the app should be fine but for now avoid
