Doesn't work with v6.6.x

Filing this mostly for visibility.
See https://community.home-assistant.io/t/wallbox-pulsar-plus-integration/200339/1195 and #62
Someone will have to change the code to subscribe to redis channels instead of reading from redis keys. The implementation will also need to work for both <6.6 and >=6.6

Hi,
Noting that 6.6 version on copper SB (and others) makes the Root/SSH process unusable, I had to downgrade to factory default. And it all worked again. However, I am now stuck with a 5.2.5 vesion which is from early 2021. Needless to say that there has been several improvements first.

So is there a way to upgrade to a version 6.5.2. The first step would be a get our hands on the firmware update URL or package.
Then a method through SSH ?
Or I noted there is the feature via OCCP tools, but again it requires a specific URL to the upgrade pacakge.

I realise this is not directly related to this repo. I have searched elsewhere without success.

Looks like you can indeed update to a specific version! In essence, wallbox's firmware update is just a dpkg install procedure.

Here's the script that does the updating: https://pulsar-repo.wall-box.com/pool/main/s/sys-update/sys-update-1.5.0-all.deb

I think it's kind of tricky though as that repo doesn't seem to contain any 6.x firmware at all - maybe it's just for restoring functionality?

When you click "update" in the app - it's the app on your phone that is downloading the .deb and sending it to the charger, then charger executing an "offline" install.
Where does the app get its .deb's - I don't know, however.

The app gets an encrypted and signed tar.gz over a HTTP API. Inside is essentially a deb repo and some metadata.

Yeah but how do we get this .tar.gz by ourselves, preferably any version we like? 🤔
