I wanted to monitor my new (to me) EX switch and couldn’t find a good way to do it in HA, so I wrote an integration. Right now it just monitors all interfaces - interface status, bps, and pps rates. I plan to add a way to enable/disable ports and PoE and also add system status information such as CPU, memory, temperature, fans, etc. If anyone tries it out and has other recommendations, add them to the issues.
This integration should work with basically any Junos device, so if something doesn’t work, please let me know.
