If you need the latest available firmware for your Ensto Chago charger, find it below.

You can use USB stick based method (see Update firmware with USB stick) or OCPP FirmwareUpdate request to update the software. You can only go to a newer version, not back to an older version, this is by design.

Note: In case the charger is connected to any back-end, before updating please check with the back-end operator what is the latest approved firmware version that can be used with their back-end.

Note: The type 2 charging cable must be disconnected from the charger to activate the firmware update process (update may be postponed forever if the cable is connected forever - "update already in progress" - status notification).
