Our beta tester got his unit yesterday and thanks to his feedback I made changes to the installation page. You MUST install the websockets plugin for OBS before configuring if that’s your platform. Tally Pro communicates with OBS through a websocket, a persistent connection using a specific IP address and port. Vmix and the ATEM use different methods.
Also, if you use the same computer to run OBS or Vmix and use a browser on it when you program the light, the IP address may change when you connect first to the light and then back to your WiFi network. Avoid this by assigning a fixed IP address to your computer!
