I’m having similar issue after swapping to Octopus. Previously the Ohme charger had my EDF tariff in its database so could select that tariff. It doesn’t have my new tariff and even though I’ve manually added the dual rates it isn’t happy. The Octopus app wouldn’t play nicely with the Ohme app or my car after I paired both in the Octopus app. The Ohme price cap function isn’t working. I’m hoping that at some point Ohme will update its database and I’ll get back to ‘smart charging’.
I would advise using Ohme app only and not Octopus app.
I have Ohme Ipod charger fitted and OVO as energy supplier through the VW 10,000 free mile and guaranteed 7p cheap rate. However, found it difficult to get the Ohmn app to work as it doesn’t recognise OVO? I currently use it as a dumb charging point controlling it through the OVO app and the Skoda app. The difficulkty is that sometimes the charger doesn’t seem to want to communicate with the car when plugged in? Any ideas?
OVO community forum is best place to ask.
