Based on Acer Projector core integration.

The following device infromation is polled:

• Power state (ON/OFF)
• Lamp use in hours and minutes. This is calculated in Low mode
• Lamp Mode
• Current Source
• Signal presence of current source
• Power state change availability

After the device is switched on or off, there is a device based block on changing the state again (manufacturer documents 10 seconds, but may be longer) . Power state change polls this.

Copy the mitsubishi_projector folder and all of its contents into your Home Assistant's custom_components folder. This is often located inside of your /config folder. If you are running Hass.io, use SAMBA to copy the folder over. If you are running Home Assistant Supervised, the custom_components folder might be located at /usr/share/hassio/homeassistant. It is possible that your custom_components folder does not exist. If that is the case, create the folder in the proper location, and then copy the mitsubishi_projector folder and all of its contents inside the newly created custom_components folder.

Alternatively, you can install mitsubishi_projector through HACS by adding this repository.

Add the proper entry to your configuration.yaml file. Several example configurations for different device types are provided below. Make sure to save when you are finished editing configuration.yaml.
