Based on different documentations found on the internet, we had a problem with the suggested blazer_usb driver. It does not allow to send commands trough upscmd such as shutdown.return. To overcome this problem we used another driver nutdrv_qx.

Now, our homeassistant is not happy with it since we do not have the battery.charge attributename anymore. We had to manually enable the battery.voltage attribute and now everything is working.
