Smart home without remotes, but with a cube

Problem

During the repair of a new apartment, I returned to the apartment where I had not lived for 10 years and decided to practice the discipline “Smart Home” in order to equip a new apartment with knowledge of the matter. The equipment in this apartment is also not the smartest and not the newest, because it was produced ~ 10 years ago. Most of all in the apartment I was bothered by the abundance of infrared remotes, they were lost and loaded the brain with the selection of the right one. Until recently, it was decided to make a huge number of unused buttons on the remote controls. And the consoles are neither aesthetic nor hygienic, some are angular, others with rounded edges, the buttons turn yellow, and the remnants of the inhabitants' life accumulate on them, which form a “sub-button biocenosis”. As a result, a dozen remotes are scattered around the house with a bunch of unnecessary buttons, for simple operations I had to look for two or three pieces, their look scratches my eyes,I wanted a comfortable tactile and fashionable voice control.

The trouble from China does not come alone, except for the brakes to rub has become the inability to screw a smart cube to the sound control.

The Home Assistant itself needs to be launched somewhere, Synology DS718 + came up under this task, which was used as a DLNA media center and torrent download. This device is able to run Docker containers, and a container with Home Assistant is easily wound up in it. Home Assistant is cool, but unlike Mi Home, you need to write all the smartness of a house in it with pens in yaml. Having mastered the DSL understood Home Assistant and spitting from another programming tool that does not require knowledge of the PL, I managed to cook up a crutch of the desired shape.

- id: volume_up
  alias: Volume up
  trigger:
  - event_data:
      action_type: rotate
      entity_id: binary_sensor.cube_0000000103ec74
    event_type: xiaomi_aqara.cube_action
    platform: event
  condition:
    condition: template
    value_template: "{{trigger.event.data.action_value> 0}}"
  action:
  - service_template: "script.bbk_vol_up _ {{(trigger.event.data.action_value / 3) | int}}"

This automation catches the clockwise rotation event and calls a script in whose name the number of sound increase signals that the infrared emitter should send is substituted. As you probably guessed, each corner of the rotation requires its own script, copy-paste was called to create them, and it gave me 20 scripts like these:

bbk_vol_up_10:
