Cover AM43 Default to blue tooth "off" (How)

Hi I have AM43 controller running from an ESP32

switch:
  - platform: ble_client
    name: "Office Curtains"

The normal “restore_mode: ALWAYS_OFF” is not accepted.

How do I turn off this switch by default if the ESP32 reboots

Regards, Dave

perhaps on_boot:

Hi, thanks that worked, had to add id to switch and a delay on_boot

here is my code to help others

esphome:
  name: office_curtains
  platform: ESP32
  board: nodemcu-32s
  
  on_boot:
    priority: 600
    # ...
    then:
    - delay: 1000ms 
    - switch.turn_off: blutooth_on_off

switch:
  - platform: ble_client
    id: blutooth_on_off
    name: "Office Curtains"
    ble_client_id: office_am43

Once again thank you
