scrcpy VS KeyMapper

There's also https://github.com/Genymobile/scrcpy which works for any Android, not just Samsung

How did you manage that? I mean, what's the app name? Maybe srcpy can help you: https://github.com/Genymobile/scrcpy

GitHub - Genymobile/scrcpy: Display and control your Android device

Needs android 11 tho https://github.com/Genymobile/scrcpy/blob/master/doc/audio.md

View and control the watch from the PC with scrcpy (only Wear OS 3).

Key Mapper app of your choosing. (this is so you can access the home menu of launcher you decide to install since the home button will just take you back to the adth app they use) I will use this one: https://github.com/keymapperorg/KeyMapper

Key Mapper itself is FLOSS (Free/Libre open-source software), the source code is here. Another possibility is Volta, but Key Mapper is better.

I really do need to trigger these bindings programmatically: I'm using bash's keybinding functionality to supplement an app called Key Mapper which is no longer being actively developed. I'm using Key Mapper to execute shell scripts in Termux. These shell scripts contain variations of the printf command from above which trigger my bash keybindings.

Using Key Mapper (https://github.com/keymapperorg/KeyMapper) (https://docs.keymapper.club/user-guide/adb-permissions/), I have assigned camera button + # button to lunch the keikai launcher, and I had to reassigned the camera button to open the camera.

FYI you can remap any button on your remote to open Plex (or other app, function) with KeyMapper https://github.com/keymapperorg/KeyMapper

Do you mean with a BT keyboard attached to the tablet? One approach is to use keymapper:

market: https://play.google.com/store/apps/details?id=io.github.sds1...

github: https://github.com/keymapperorg/KeyMapper

fdroid: https://f-droid.org/packages/io.github.sds100.keymapper/

It's a very versatile tool, can be handy even if you don't have a keyboard.

using the program KeyMapper how can i make holding a button toggle a light bulb in home assistant?

I don't know if it's the same with the onn, but with the google device you can use the Key Mapper app.

You'll have to see where the service capabilities are listed. This'll be xml folder here -> https://github.com/keymapperorg/KeyMapper/blob/master/app/src/main/res/xml/config_accessibility_service.xml

I never got much out of Easer, but I did come across Key Mapper, which lets you assign actions to button presses. I set up a mapping so that a double-click on volume down will activate the flashlight. Not quite as cool, but it's a pretty decent alternative.
