It's failing to read the manufacturer of one of your devices. I may have wrongly assumed it would use utf-8 encoding. Yours seems to be the first device that uses a special character.

Please inform me the exact name of the manufacturer of this device (can't know for certain which one it is, but the first letter is special). If it's Ç, this will be an easy fix.

I have a "PAS600" panel server and six "A9MEM1521" schneider electric powertags.

@lillson I can't fix this for you right away, so here's a temporary workaround for you:

1. Go to config/custom_components/powertag_gateway/schneider_modbus.py
2. Find def manufacturer(self) -> str | None: on line 772
3. Make it look like this:
   

You will have to reapply this fix every time you update the integration I'm afraid. Will keep this issue open until a proper fix is found.

@samdaenen this still an issue for you?
