Since I'm not sure when the JVC projector driver is going to be updated to support the required password on the NZ lineup I decided to install the JVC HomeAssistant driver. That's all fine and I was able to see the device in the HA driver. But fundamentally I'm missing something because the macros for turning on/off the display are looking for the <room>_display_id server variable. Where does that get defined? I can certainly hardcode the device ID in the macros but it seems like there is supposed to be something that automatically does that. Can someone from Allonis help me understand what I'm missing?
