I signed up for Octopus in the end using Paul M referral link (Due to him making a donation to a charity of my choice). I then went to the Ohme website and ordered the charger at £199 for Octopus customers. Just one question, will the Ohme charger still work if I change energy suppliers at some point in the future? Or is it locked to Octopus? Also is the Ohme charger totally controlled by an app, or is there is manual override button on the charger to initiate a charge if I loose my phone etc?
