# homebridge-epson-projector
A homebridge plugin to control [Epson EH-TW7200 LCD projectors](https://www.epson.de/products/projectors/home-cinema/epson-eh-tw7200) connected via an RS-232 serial interface. This plugin enables the integration of the projector in HomeKit automations, create rules and scenes that depend upon the state of the projector, and enables scenes to control the TW7200 projector.

## Supported Epson projectors
Epson projectors that have a RS-232 interface are likely to implement the [ESC/VP21 protocol](https://www.google.de/search?q=ESC/VP21+protocol) that is used by this plugin. While the feature set exposed on the interface differs in the projectors, basic functionality should work in almost all of them. Specifically this plugin is compatible with the following models:
* EH-TW7200
* EH-TW8200 (not verified)
* EH-TW8200W (not verified)
* EH-TW9200 (not verified)
* EH-TW9200W (not verified)
* PL-HomeCinema 5030UB (not verified)
* PL-HomeCinema 5030UBe (not verified)
* PL-HomeCinema 6030UB (not verified)
* PL-HomeCinema 4030 (not verified)
The above models share the same set of commands that are used by this plugin. Other models not on the list might be compatible to a certain extent, see [Contributing](#Contributing) for more.
## Installation instructions
After [Homebridge](https://github.com/nfarina/homebridge) has been installed:
```sudo npm install -g homebridge-epson-projector-rs232 --unsafe-perm```
### Configuration
```json
{
"bridge": {
...
},
"platforms": [
{
"platform": "EpsonProjector",
"devices": [
{
"name": "Epson EH-TW7200",
"port": "/dev/serial0",
"pollingInterval": 60000
}
]
}
]
}
```
The configuration of a projector consists of the platform name, a list of devices, the name of the projector and the port it
is connected to. The polling interval regulates how often the plugin should query the projector for the current status. Note that
the default value is 60000 milliseconds. You can go as low as 1000 milliseconds if you require faster status updates in HomeKit. The projector will be polled with this frequency at all times, when it's powered on and powered off.
## Hardware setup
Unfortunately I'm not a hardware expert on setting this up. I've found the following configuration to work for me on a Raspberry Pi Zero W, however be aware that you might break stuff if electrons flow in unexpected amounts and directions. Also please be careful when working with electricity and electrical circuits. I will in no way take responsibility for your actions.
You need a serial cable to connect the projector to a computer or a Raspberry Pi. A USB powered serial adapter might work for you, I've good experience with (real) FTDI chips.
If you're creating your own solution for this, it is recommended that you use a MAX3232 IC to connect the projector with the Raspberry Pi for proper circuit protection to both devices.
### Disable serial TTY on RPi
On a Raspberry Pi you additionally need to:
- Disable the login shell on the serial port
- Keep the serial port hardware enabled
If you run homebridge, the user account running homebridge must be a member of the dialout group.
## Supported clients
This platform and the switches it creates have been verified to work with the following apps on iOS 11:
* Home (only the Power switch is available in the Home app, all other services are `Not supported`.)
* Elgato Eve
