I have an HTD whole house audio lync 6 system , it uses a IP to serial gateway (GW-SL1 Smart Gateway) which has a mobile app that can control zones and also via a key pad.
I am trying to figure out how to send serial commands to this device using vera . I have done some research but having no luck . Any help would be great! . It should be quite similar to the Russound RNET
Here is a link to the manual .
