Tracking the current ISP

In our RV, we are using a Unifi Ultra Gateway that has multi-wan support. I am using two Invisagig modems, one tied to Verizon, the other AT&T. I like to monitor which ISP we are using since once can be set as primary, and the other secondar/failover. I use this to notify me if the primary source is not being used for longer than a few minutes. LTE/5G has a few drops, failover is great, but if it does not switch back I would like to look into it.

This setup will work if you are using other common RV internet solutions like Starlink, T-Mobile Home Internet, or anything else.

ipify, a free service allows you to get the the details of your IP address, including the ISP.

Node Red

I am using Node-Red to make the simple API call, parse out the information I want, clean up the response and pass the result over to Home Assistant.

Below is my current Node Red flow

This will output a sensor in Home Assistant called sensor.current_isp that I display on my dashboards and use in automations.
