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
