Thats good news I hope 🙂
You now need to set Ohme to only charge during the 4 hours cheap rate window by setting the price cap and turning it on in the app, with a finished/departure time of say 4.30am.
Or set the car up to act as a timer, as described above.
You only need to adjust the schedule departure for tonight as a test. You can test a timer schedule doing it via the car tomorrow night if you wish a pick which one best suits you.
Fingers crossed for in the morning.
