Amplifier power control via relay and GPIO, I2C (Add-on)

Hi LE community,

I am newbie in LibreElec and Python. I wrote an addon for control amplifier power using GPIO output and relay. It set 1 to GPIO output if KODI is playing any video or audio file and set 0 after timeout. Addon have settings:

Timeout - from 2 to 20 minutes

gpio pin - it will be used for relay control

Notification - notifications will be showed on turning or turning off.

So maybe more experienced users can take a look and tell if everything is ok with this addon?

Hi to all,

I want to add i2c volume control to my add-on (pt2257 for example).So I have some questions:

How to disable built-in KODI volume control (maybe keymap editor)?

How to capture volume key press (IR, keyboard, KORE)?

Can I use kodi volume slider for display current level?
