This binding was created to connect a Panasonic PT-AE8000U projector to openHAB. It should work with other later model Panasonic projectors with a serial port but no testing with other models has been done. The binding is compatible with openHAB 3.1 and later.
Supported Things
This binding supports two thing types based on the connection used: projector-serial and projector-tcp.
Discovery
The projector thing cannot be auto-discovered, it has to be configured manually.
Binding Configuration
There are no overall binding configuration settings that need to be set. All settings are through thing configuration parameters.
If you receive an error about openhab-transport-serial, issue the following command in the openhab console:
feature:install openhab-transport-serial
Thing Configuration
The projector-serial thing has the following configuration parameters:
| Parameter | Name | Description | Required |
|---|---|---|---|
| serialPort | Serial Port | Serial port device name that is connected to the Panasonic projector to control, e.g. COM1 on Windows, /dev/ttyS0 on Linux or /dev/tty.PL2303-0000103D on Mac. | yes |
| pollingInterval | Polling Interval | Polling interval in seconds to update channel states, range 5-60 seconds; default 10 seconds. | no |
The projector-tcp thing has the following configuration parameters:
| Parameter | Name | Description | Required |
|---|---|---|---|
| host | Host Name | Host Name or IP address for the serial over IP device. | yes |
| port | Port | Port for the serial over IP device. | yes |
| pollingInterval | Polling Interval | Polling interval in seconds to update channel states, range 5-60 seconds; default 10 seconds. | no |
Some notes:
- The source channel includes a dropdown with the source inputs for a PT-AE8000U.
- If your projector has a source input that is not in the dropdown, the three character code to access that input will be displayed by the source channel when that input is selected by the remote control.
- By using the sitemap mapping or a rule to send the input’s code back to the source channel, any source on the projector can be accessed by the binding.
- The channel picturemode is pre-populated with options for the PT-AE8000U
- On Linux, you may get an error stating the serial port cannot be opened when the panasonicprojector binding tries to load.
- You can get around this by adding the
openhabuser to thedialoutgroup like this:usermod -a -G dialout openhab. - Also on Linux you may have issues with the USB if using two serial USB devices e.g. panasonicprojector and RFXcom. See the general documentation about serial port configuration for more on symlinking the USB ports.
- Here is an example of ser2net.conf you can use to share your serial port /dev/ttyUSB0 on IP port 4444 using ser2net Linux tool (take care, the baud rate is specific to the Panasonic projector):
4444:raw:0:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT LOCAL
