Good point.
I do however have an Ohme charger and it's been giving me lots of trouble when using Agile Octopus (but the type of trouble like related to battery level would impact if I used Intelligent Octopus). I had trouble for the last 6 months. I wish I had waited for the wallbox.
Today for example, (after a lot of trial and fail.. ), I set my Ohme app to accept up to 12p pricing (Zeus is blowing the windmills at full power 😉, variable pricing paradise). I looked at the app and it said nothing available, wait for tomorrow´s pricing (available in 7 hours). This is even when all the pricing periods this morning were below 4p - according to the same Ohme app! I tried restarting the charge session in the car, restart their app, reboot from the RCD, nothing fixed it, not immediately.
I also read comments about their support desk being very poor. But with what I am seeing, a weaker link are their testers, or maybe they are missing altogether. The Ohme app says no price below max available. Just after one tap, you can see several.. 😡
