I've developed this integration to monitor my Arris CM3500 Cable modem status.
I hope this integration will be helpful for you as well.
I recommend installing it via HACS
Currently, integration is not part of the HACS, so you will have to add the repository manually:
- Go to HACS -> Integrations
- Add this repo to your HACS custom repositories
- Search for Arris CM3500 and Download it
- Restart your HomeAssistant
