Possible to Support Projector as TV/STB/Streaming Device?

[ahmadnazirafiq]

Device model fengmi.projector.fm05

Device name Xiaomi Smart Projector (Fengmi Young)

Does the device require a MiCloud connection? Do not know

Anything special about the device? No

I’m not sure if this is even possible but I don’t see any plugin are able to expose a Xiaomi projector as a television/set top box/streaming device to HomeKit. Currently relying on Siri Shortcuts but its unreliable and breaks everytime there’s an iOS update.

It should actually work. You can already do it now, just add the device into the plugin and it should be detected automatically. Although it will be detected as a generic device, you can use the actionButtons and propertyControl to expose to HomeKit whatever you need and be able to control it.

[ahmadnazirafiq]

I did, but it shows as not supported in the Home app, with a generic “home” icon on it and no buttons at all.

With this warning, adding actionButtons or propertyControl yields no response:

I should tell you that this projector only showed up on Mi Home app after I’m signing in to the same account on the projector — not by the usual pairing like other accessories.

The plugin does not supports TV accessories yet so that is an expected behavior, but it should not cause any issues. You can post the homebridge debug so i can have a look what it dos not work, it might be that it requires a micloud connection...

The log is not enough as I do not see if the property sync is working, meaning if the plugin could connect to the device. You need to post some more log.

[ahmadnazirafiq]

It seems like I can't connect to the projector to turn it on, however I can use the specified propertyControl to turn it off. It only starts connecting once the projector wakes from sleep even though it has already been powered on. Detailed logs with deep log enabled in the plugin:

Yeah, it seems that it only has a turn off action, so I guess that it goes in some kind of a deep sleep when in standby hence it is not possible to turn it on. But besides that it looks good I guess.

[ahmadnazirafiq]

Yeah, but the weird thing is there is one device that can remotely turn on the projector: Mi Smart Clock (xiaomi.wifispeaker.lx04).

See below the manual automation I made in Mi Home app, in addition of the other skills it can do VS the spec fetcher gained from it.

The thing is I struggled to put those data for propertyControls and Action buttons as none of them seem to work. If the projector was indeed in deep sleep, why is this smart clock were the only device that can wake it up remotely?

[merdok]

It might be that the device uses wake on lan to wake up. You can try to send a magic packet using generic wake on lan tools to the MAC address of your device to test it out. In the miot spec there is nothing to turn it on hence it will never work over the miot protocol. It also makes sense since the device only can listen to protocol calls when it is turned on and running.

[ahmadnazirafiq]

After tested it myself, it seems like:

1. Wake up with CEC - No
2. Wake on LAN - No
3. Wake via ADB - No

Despite going into deeper sleep mode and is not on the network, I think the reason why is that Mi Smart Clock were using BLE to turn on the projector (it even shows up on Spec Fetcher, see below). I went so far to even root the projector but no luck.

I wonder if what it says "ble-control:turn-on" is enough of a clue 🤔

[merdok]

Yeah, not really sure what it means. I mean to execute an action the plugin needs to be connected to the device and you say that the device is not available in the network as long as it is turned off... so not really sure how the app does the turn on then.

[ahmadnazirafiq]

I think the app sends the command to the cloud then to the smart clock. the clock then initiates the BLE control to turn on the projector. At least that's how i see it via Mi Home app.

It's okay, guess i'll stick to Shortcuts for now. Thanks!
