PJLink
pjlink
The PJLink integration allows you to control PJLink-compatible projectors from Home Assistant using the PJLink protocol.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
media_player | Media player (as switches) | Only TVs and receivers get a TV tile; other players show as power and play switches; Needs its own HomeKit Bridge in accessory mode |

| Optoma UHD60 | Partly works Local | Works once a name is set in configSaved copyAdding the "name" attribute to the config seems to solve this (fixed on an Optoma UHD60). It should also solve the unique id problem that @snuf72 indicates as "name" is now used as the unique id for the device. This is still a bug, as it appears there is something wonky with the name of the device returned from some PJlink devices and/or how this plugin deals with it. For clarity, this example should work: [code] Excerpt saved from GitHub on 2026-10-23. | Issue #118934 · 2024-10 | |
