Install instructions need upgrading after HA 2026.1

[lizdodd]

Having got my dishwasher back on the wifi reliably (see previous issue) I managed to download all the extra programs for the dishwasher.
I wanted to update the data in devices.json

Install from https://github.com/hcpy2-0/hcpy/wiki/HomeAssistant-Addon directs one to /mnt/data/supervisor/addon_configs/ This doesn't exist without 2 further steps

~ mkdir -p /mnt/data/supervisor/addon_configs

~ mount /addon_configs /mnt/data/supervisor/addon_configs

Then I was able to proceed to the next phase.
Having finally retrieved my codes I was unsuccessful in making a new devices.json despite 6 or 7 tries

I find the steps quite difficult to follow, not helped by the difficulty of pasting out of the Advanced SSH, as a Ctrl-C to enforce a copy closes the hc-login.py script.
I would offer to rewrite but I need to solve the second part of the install beforehand.

Have you found a solution?

I believe I just use right click and copy rather than keyboard shortcut when accessing the advance terminal in the browser?

[lizdodd]

I haven't found any solution, it just dropped to the bottom of the "to-do list". I can do what is important for me with the dishwasher using the hcpy add-on.
