Second most expensive thing people will buy,
I've got an original Ohme Home charger and had same experience. It's like they don't really get any input from EV owners. That said, they were great at fixing a bug I came across. I've forgotten all the issues I had with it, including why it simply won't do what I expect it to at times.
I stopped using the Ohme app as moved to a smart tariff and used the energy supplier's app. That's got similar issues too, not really doing what I expect to. For example, tell it to charge to 80% by 6am and at 6:20am it's still charging the car and is on 92%. I understand why they might do that, as it's using the extended cheap rate electric that has become available(probably!), but at least give users a simple checkbox that states "Stop charging at this %".
Also had an issue recently where I plugged the car in and it started charging and the energy supplier's app didn't recognise it was plugged in for around 25minutes, during which time I was being charged at the daytime rate. Reading into it they advise keeping an eye on it when plugging in and taking action to manually stop the charge session if it happens. So much for "smart" charging. Probably not entirely their fault as rely on the BMW service but it's all just still a bit flaky.
I've now moved to using the Ohme app again and just charging midnight to 6am as don't have confidence in the energy supplier's software managing charging during any daytime cheap rate periods, or, as above, charging for a while during the daytime as it's not detected the car is plugged in. However, I've realised I need to take about 10% off the SoC I input when I plug in as Ohme is overcharging the car by that amount and they don't have access to the BMW api anymore to automatically obtain the current SoC.
