ocpp: add update firmware function

[drc38]

Hi @lbbrhzn, this function can be used for a custom service call when ready as referred to in #34

Ok guys,
Good news, my charger just (month old) got a firmware update released.
So I can test this feature from the moment you merge this into main.
You are talking about the firmware_url any idea where I can locate this?
The charger product page has a link to a firmware page: https://www.se.com/ww/en/download/document/MFR4341700/
But behind the download button is a zip file containing the file with the firmware.
If I read your code you need the update file directly.
Or should I ask Schneider for a public url where the file is hosted?

Hi Jeremy, there's still a bit or work required before this function can be used in HA as a custom service. So it won't be available after the merge. Your charger may accept the zip file directly, otherwise you could unzip and load to onedrive or similar cloud server. The metric "FW.Status" can be used to monitor the update process. I take it your charger supports the Firmware Management profile?

[jeremycoppey]

Yes my charger supports the following:
Core, FirmwareManagement, Reservation, SmartCharging

I will do a manual update then.
Looks like it adds some extra features:

Do you know what they mean with this feature? (see page 7 of the release notes)

Clock aligned values are for accurately reporting energy used in given time periods eg 30min or 1hr required by Energy Retailers / Billing solutions. Not really of use for most personal applications.

If you can hold off the manual update it would be useful to be able to test this feature when it's available. My charger is already on the latest firmware.

[jeremycoppey]

sorry I just updated.
But as they release frequently I don't think I will be waiting long for a new firmware update.

Thanks for the clarification.

hi @drc38, these changes look ok, thanks! I cannot download new firmware for my Wallbox charger myself, so I was not able to fully test it.

Just a minor point: the pre-commit check for the formatting is failing. Did you run a pre-commit check before you pushed your changes? Just use pip install pre-commit to install

[drc38]

@lbbrhzn, thanks I wasn't sure whether the pre-commit process was supposed to do the reformatting or whether I needed to do it locally.

@lbbrhzn, thanks I wasn't sure whether the pre-commit process was supposed to do the reformatting or whether I needed to do it locally.

You need to do it locally. The pre-commit actions are also done as an action on GitHub, and it will result in failed checks if there are still some formatting issues remaining.
