Hi guys,
I own the non 4K international version of the Xiaomi  laser projector   mjjgyy02fm since a couple of weeks. I'm also using a Fire TV Stick 4K instead of the pre installed android 8.1 software for any kind of streaming (Netflix...).
As far as I know it is not possible to boot directly to the fire TV stick.
As a workaround I would like to use my Logitech harmony hub with a script to switch directly to the fire TV stick after booting android but:

1) Issue switch on button. 
There is no profile in the harmony database for the international version mjjgyy02fm. 
As a workaround tried to use the Nvidia shield TV profile  from the harmony database but the switch for turning the projector on is not available. 
As a workaround for the missing on button I made a script with switching on the fire TV stick first. Idea is to use the CEC signal which should switch the projector on. But it works more or less in 1 of 10 times. 

2) Issue: Select different source

The Nvidia shield profile which I'm using for the harmony, doesn't contain a "source selection" button. But this is mandatory to me because I don't wanna use the android surface (missing Netflix...). Instead of this I would like to use the Amazon fire TV stick which is assembled to input HDMI 2 of the projector. 

Today I got a hint that flirc might be a solution. But before buying this little peace of hardware I would like to get an info if this might work with the Xiaomi Laser projector. 

Idea would be:

1. Assemble flirc to projector

2. Connect and configure flirc with harmony

3. Switch on projector via harmony/flirc combo. 

4. Select HDMI2 as source

5. Use fire TV stick with harmony 

 

Many thanks in advance and best regards from Germany

One additional remark. The remote for the projector works via Bluetooth
