Hass.io: running "hassio homeassistant *" cli commands as shell commands

Those services indeed work well if they exist. There’s no hassio.update service to initiate the update of HA.

I use telegram with ssh addon…

  - id: ha_update
    alias: ha_update
    trigger:
    - platform: event
      event_type: telegram_command
      event_data:
        command: /update
    action:
    - service: hassio.addon_stdin
      data:
        addon: a0d7b954_ssh
        input: '/usr/bin/ha core update'

but the option share_sessions: Is set to false
