KeyMapper VS Rekado

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.

When using with your phone, you often need a USB OTG adapter. If you're using Android, I'm assuming you're using Rekado. Here's an excerpt from their GitHub page about this:

RCM Loader is not worth of your money, I suggest you to buy an adapter for your phone, installing Rekado and connect your phone with adapter with your Switch. You need something like this, Adattatore USB-C a USB-A 3.0 OTG, USB Femmina a USB-C Maschio Compatibile con MacBook Pro, Samsung Galaxy, Telefoni di Tipo-C, Tablet e Altro (Nero e Bianco) https://amzn.eu/d/eKTem8B). Be sure that it can transfer files and you save 25-30 bucks. For the jig, I bought on Amazon, idk if you can buy it from here. I heard of some people that "handcrafted" their jig with hairpins, idk if works, you should try

Yes, theres an app https://github.com/MenosGrante/Rekado/releases

Some advice for after you've booted into custom firmware and got it all set up: consider using AutoRCM. It corrupts a single byte in the Switch's bootloader which causes it to boot automatically into RCM after every power cycle, eliminating the need for an RCM jig entirely after the first use. All you need to do then is inject your chosen payload using Rekado (if on Android), or iOUSB (if on iOS).

If you have android phone you can use that use the app called rekado that's what I use https://github.com/MenosGrante/Rekado/releases

After looking into how Atmosphere boots by looking for a reboot_payload.bin which you can have as ANY payload file (mine is Hekate) I've not needed to inject it by hand in a long time. And if I do ever need to I do it with my phone even using Rekado
