# PJLink2 for Home Assistant
|
|
|
|
|
|
+[Home Assistant](https://www.home-assistant.io) custom component to integrate video projectors via the [PJLink](https://pjlink.jbmia.or.jp/english/index.html) network protocol.
|
|
|
+In contrast to the official [PJLink integration](https://www.home-assistant.io/integrations/pjlink), it also supports PJLink class-2 features, notably querying the current resolution of the projector.
|
|
|
+The projector is integrated as a sensor that shows the current state (ON/OFF), all other data fields are attributes to the entity.
|
|
|
+
|
|
|
+## Tested devices
|
|
|
+
|
|
|
+The component has been developed and tested with an Epson LS12000 projector, but should work with all models and brands that support the PJLink protocol, among them Sony, NEC, Panasonic, Optoma, BenQ, and many more.
