We currently do not offer an option to delay the start time of your smart charging sessions. However, several other features should ensure your vehicle only starts charging when it is most favourable for you according to your energy tariffs.
For example, if you have a double tariff (peak/off-peak), you can always use the "charge only during off-peak" feature to ensure charging is only starting at the off-peak rate.
Please keep in mind that this is not possible if your car does not support managed charging: Is my car supported in the Jedlix app?
