IMPORTANT CHARGING INFO ONLY FOR OHME CHARGER USERS WITH OCTOPUS ENERGY INTELLIGENT GO CUSTOMERS
Here is the information from OHME
For the Ohme integration with the Intelligent Octopus Go tariff, as long as you charge the car on an overnight 'Charge Schedule' (set in the Ohme app > My Charger) with a 'Departure Time' for the next morning, all charging will be considered smart charging and will be billed at the off-peak rates.
This is the case whether the charge took place between 23h30 and 5h30 or outside of those times. Octopus and Ohme advise keeping the Price Cap setting disabled in order to benefit from these extra half hour off-peak slots.
Please note Octopus do advise to plug the car in after 5pm and set your Departure Time for between 4am and 11am.
Before plug-in, make sure your charger is online and connected to the Ohme server. You can check this in the Ohme app on the My Charger page.
After plug-in, check that the Ohme app dashboard background stays blue and says 'Smart Charging' at the top, together with the name of your Charge Schedule. This will be the reassurance that all used timeslots for the current session will be billed at the off-peak rates.
If you see a red screen and the words "Max Charging" or "Charge to Full ASAP" at the top, this indicates a boost charge is happening. If it seems the Ohme app has not registered the plug-in, or that charging has started, this might mean your charger is offline.

A boost charge, or an offline charge will mean the current charging will be billed at the higher rate (unless it falls between 23.30 and 05:30am).
