Telnet commands to FourKay 4K HDBT switcher

General

Hello,

I have a Fourkay (OREI) HDBT matrix which I would like to integrate with Home Assistant through Node-RED. See: https://www.youtube.com/watch?v=i756a9TwtpQ

I'm able to send Telnet commands through Putty without issues but I have been unable to do it through Node-RED.

I installed the node-red-contrib-telnet-client to test but that hasn't worked either.

Can anyone send me in the right direction?

Welcome to the forum.

Looking at the documentation - there is no 'telnet' - did you connect it using RS-232 ?
If yes, then you may need install the serial port node

if he's sending command via putty then yes there is (even if its a slightly different model) ... usually the issue is adding the correct "enter" key character at the end of the line - often you need to add \r or sometimes \n - or both or something else...

I've tried \n but not \r or both. I'll give that a try.

For reference, it was \r

Thanks!
