ZHA and IKEA shortcut button E1812

[hrw]

I moved from Zigbee2MQTT to ZHA. And found that Ikea shortcut button E1812 is not supported.

This blueprint works for me:

name: Ikea Shortcut E1812
service: ZHA
event_type: zha_event
identifier_key: device_id
buttons:
  - actions:
      - title: press
        conditions:
          - key: command
            value: "on"
          - key: cluster_id
            value: 6
          - key: endpoint_id
            value: 1
      - title: press 2x
        conditions:
          - key: command
            value: "off"
          - key: cluster_id
            value: 6
          - key: endpoint_id
            value: 1
      - title: hold
        conditions:
          - key: command
            value: "move_with_on_off"
          - key: cluster_id
            value: 8
          - key: endpoint_id
            value: 1
      - title: hold (released)
        conditions:
          - key: command
            value: "stop_with_on_off"
          - key: cluster_id
            value: 8
          - key: endpoint_id
            value: 1
