BenQ Projector Binding - vpjuslin/openhab GitHub Wiki
This binding is designed to interface with BenQ projectors that have an RS232 interface on them that accepts the commands documented by BenQ in [1].
This binding is current in Beta state with the following commands implemented:
| Command | Query | Set | Comments |
|---|---|---|---|
| Power | Y | Y | |
| Mute | Y | Y | |
| Volume | Y | Y | |
| Source | Y | Y | Can be returned as either a string or number |
| Lamp Time | Y | N |
Tested Devices:
- BenQ W1080
The binding has currently been developed using a TCP/IP to RS232 converter. A direct RS232 interface needs to be implemented.
Known working converter is the USR-TCP232-2.
