The goal of this fork is to experiment with changing the supported protocol to enable talking to Epson projector with serial connection. This is highly experimental - don't use it.
Moreover, the following documentation is not up-to-date.
Home Assistant integration that supports sending commands to BenQ projectors over the serial interface.
BenQ projectors and flat pannels with a serial port can support one of three protocols. This plugin supports projectors which are of the L, P, T, W and X series but probably also others.
This integration works if your projector has a serial port and supports the following command structure:
<CR>*<key>=<value>#<CR>
Where <CR> is a Carriage Return
Example:
Power on : <CR>*pow=on#<CR>
The same commands should work over a network connection, but I don't own such projector and have not implemented any network functionality. Contact me if you have a network connected BenQ projector and like this to work.
This integration does not implement the PJLink protocol, but a proparitary BenQ protocol instead. The PJLink protocol is covered by it's own integration: Home Assistant PJLink integration
Known to work:
- W1100
- W1110
- X3000i
Not tested but use te same protocol according to the documentation:
Others in the L, P, T, W and X Series
Not supported:
- RP552
- RP552H
- RP840G
- RP653
- RP703
- RP750
- RP750K
- RP652
- RP702
- RP790S
- RP705H
Please let me know if your projectors is also supported by this plugin so I can improve the overview of supported devices.
- Go to your HACS view in Home Assistant and then to Integrations
- Select + Explore & download repositories and search for BenQ Projector

When your wiring is right a new BenQ Projector integration and device will now be added to your Integrations view. If your wiring is not right you will get a Failed to connect error message.
