JVC Projector Remote

A python package to control JVC Projectors over IP.

⚠️ This project is looking for (co-)maintainers.

Times change, I might end up with a different projector brand, JVC might change the command interface for a newer model that I don't have. Enough people use this library now that I think it's important to think about think about its future. I would be grateful to have people who are competent in python and have access to a JVC projector on board. If you're willing to help, submit a pull request implementing new features, fixing bugs or tidying up my terrible programming and documentation!

If you'd like to make a donation to sponsor work on this project, you can donate on ko-fi, or github sponsors

References

This library is used by following software:

• JVC projector remote for Homeassistant (add-on for Home Assistant).
• homebridge-jvc-projector(plugin for Homebridge)

It can also be used standalone or in a Python script.

Command format

Read state

To read a property, use the JVCProjector.command(<command>) method.

Examples:

• Power state: send command power and the response will be standby, lamp_on, cooling, reserved or emergency
• Signal state: send command signal and the response will be no_signal or active_signal

Write state

To control the projector, use JVCProjector.command(<command>-<state>).

Examples:

• Power ON: power-on
• Change picture mode to film: picture_mode-film
• Switch lamp to high: lamp-high

Test Connection	null	Write: no write payload, used for testing connection

NOTE: Not all commands or states are supported by all models. You can easily tell by testing them on your JVC projector.

Installation

For the latest stable version,

$ python3 -m pip install jvc_projector_remote

If you want to install the latest unstable commits from this repo,

$ python3 -m pip install -e git+https://github.com/bezmi/jvc_projector.git#egg=jvc-projector-remote

Building from source

If you've made changes and want to install them, ensure you have hatch.

$ python3 -m pip install hatch

Run the build command from the root directory of this repository.

$ hatch build

Finally, you can install the package. Make sure the filename that you specify matches the one you want to install in the dist/ directory.

$ pip install dist/jvc_projector_remote-vX.X.X-py3-none-any.whl

The --force-reinstall flag will ensure that updated files are installed even if the version number of your build matches the pre-existing package.

Usage

For usage with Home Assistant, see here.

Below is an example for using this module standalone (see command format section for command strings):

>>> from jvc_projector_remote import JVCProjector

 # replace with your projector's local IP
>>> host = "192.168.1.12"

# initialise (for models older than the NZ series)
>>> projector = JVCProjector(host, port=20554, delay_ms=600, connect_timeout=10, max_retries=10)

# initialise (alternate, with network password)
>>> projector = JVCProjector(host, password="MYPASSWORD", port=20554, delay_ms=600, connect_timeout=10, max_retries=10)

# power on, power off
>>> projector.power_on()
# check status once it's on
>>> projector.is_on()
True

>>> projector.power_off()
# check if it's off
>>> projector.is_on()
False

# Send arbitrary command
# see the command format section above
>>> projector.command("input-hdmi2")

Confirmed models

This module is confirmed to work for the models listed below. It should also work with projectors in the same series as the ones listed.

• DLA-X5900
• NX5
• NZ8/RS3100
• DLA-RS440

If you've confirmed functionality with a model that is unlisted, raise an issue or submit a pull request to have it added.
