I use telnet to connect to my Russound home audio. For whatever reason, that connection frequently fails, initiating error messages for me to address. I'm not sure why this happens. The problem may be the telnet driver that I am using. Usually, I can correct the problem with a Hubitat reboot. But is there any way to reset the Hubitat telnet (not from within the driver) without a reboot?
I saw your other similar post and it sounds like an issue with your driver that communicates with your Russound system. Telnet connections usually remain connected after they are initialized so if that connection is broken then issues arise. I don’t own a Russound but will say most telnet based drivers have an initialize command that resets the connection and reconnects. Have you tried that?
I have telnet working for 3 devices and my Denon AVR is the most problematic because that receiver only allows a single telnet connection at one time. The other 2 will remain working when the Denon AVRs connection is down. I bring this up because you don’t have to reset the hubs telnet capability, it’s just the connection for an individual device.
I have webcore pistons to monitor and address when the telnet connection to my Russound fails. But that is nearly a daily occurrence. In an attempt to solve this problem, I re-boot my Russound daily at 3 am in an attempt to mitigate the telnet connection problem. I wish the Russound had IP control. This unit is old and expensive to upgrade. But that process often fails. I monitor and re-initiate the telnet connection from within the driver with my webcore pistons. And that does work, sometimes. But when that fails, I have to reboot the Hubitat. I was hoping for a different solution.
I updated back to the latest platform recently and my telnet problems worsened again. Not sure if it is the update or something to do with the driver, or both. But re-booting my hub every day is getting old.
I would suggest PMing support_team and provide your hub ID or MAC and ask them to look at your engineering logs. Since this thread is in the lounge category it might not be noticed.

Telnet is IP control as far as AVR's are concerned.
This is a very unusual situation, I have 8 devices (a marantz, an onkyo a rotel a monoprice, two Lutron integrations and 2 Global Cache devices) that have telnet integrations and have never had to reboot Hubitat to reinitialize them, granted they all aren't on the same hub.
Can you post a link to the driver that you're using as well as PM me your HubId?, I'll have a look at the engineering logs and see it there are other clues.

@mike.maxwell he uses that to control his Russound:
