megadesk-companion.yaml trying to add buttons to trigger right memory slots

[pokdeep]

Awesome devices you've created!
I'm a complete novice in esphome but looking at the layout of the yaml I thought recalling the right memory positions would be as simple as

  - platform: template
    name: "down position 2"
    on_press:
      then:
        - uart.write: "<R0,2."

but the desk doesn't move, I can see a log entry for the button press
11:29:43 | [D] | [button:010] | 'down position 2' Pressed.

my megadesk-companion.yaml

# If you get errors compiling this with esphome, make sure you are on a recent version.
# 'esphome version' will output the version you are on.

# If you want to compile in the Home Assistant esphome addon, you need to copy megadesk.h into your esphome folder
# on your Home Assistant platform.

I am looking for that feature as well, as the "toggle both-button mode" is already in there. Activating it leaves memory slots (left & right) independent from each other and also programmable in the same fashion.
But apart from the physical buttons, I am now also looking for a way to have these distinguished within HA.
