I’m interested in trying to scrape the data from my Arris cable modem - the signal stats, error counts, modem statuses, uptime, etc. It doesn’t look like there’s tags for the data, but it is in HTML tables…is there an easy way to scrape a table without individual field ID tags? For those unfamilia…

Wouldn’t it be better to just get the data from the SNMP agent on the Cable Modem? That’s where the WebUI is getting it from.

I actually attempted to find some way to do that first but was unsuccessful getting the modem to respond. It reports that port 161 is “filtered” running nmap against it and my internet research suggested that most ISPs configure cable modems so SNMP will not respond to the customer-facing interface…

@mmiller7 Is there an easy guide to getting this to integrate with my home assistant? I am extremely new to adding customization and I cannot seem to find either a good guide to integrating this on Home Assistant or even what I exactly need to do to get MQTT working. I guess I don’t understand any o…

That’s interesting, I didn’t think any of the current models still had an unsecure UI thanks to the (IMO overblown) “DoS issue” mentioned here: Millions of Arris cable modems vulnerable to denial-of-service flaw | ZDNET Basically without a login anyone could be tricked into resetting/rebooting thei…

Unfortunately I have already asked for a firmware update, but they are unable/unwilling to provide. I am also running the SB8200 as opposed to the SB6141 referenced in the article. I actually seem to be erroring out: Error running command: `/config/arris_modem_signal_scraper/arris_signal_dump.sh`, …

Thanks for the script. I’ve taken your Arris and Netgear scripts and adapted them for my Technicolor TC4400 modem: [image] GitHub - phrxmd/Technicolor_modem_scrape: Scraper for posting the signal... Scraper for posting the signal status of Technicolor TC4400 cable modems to MQTT - GitHub…

Nice! I’ve never successfully figured out the discovery stuff, but that’s nice you got it working!

I’ve the same/similar modem to what you have shown in the snapshot above [image] but for some reason the web login fails to retrieve any token. I tried to even run wireshark and the http auth showing is cgi-bin form based fields… does your auth still work without issues? or did you change it over…

So far mine still works, but my ISP also doesn’t want to upgrade customer owned modem firmware…so maybe something changed I think the most useful thing to trace was looking at the browser console “network” tab, and then in the script uncommenting some “echo” lines and running the shell script in a …

mine returns a token but it’s with 404 not found… seems something in the auth side is different or Comcast has pushed something that’s causing this failure… will try to see if i can get around it, using debugging steps you mentioned - thank you.

Sorry for the late reply. We now have Ken Schulz’ Cable Modem Monitor Integration.
