I have this sensor (sensor.livingroom_temp_current_setpoint)

And i want to display what it is in a message, should this work ?

service: notify.mobile_app_steve_iphone
data:
title: Living Room Radiator
message: “Temperature is set to: {{ sensor.livingroom_temp_current_setpoint }}”

Please format code correctly. You want:

- service: notify.mobile_app_steve_iphone
  data:
    title: Living Room Radiator
    message: "Temperature is set to: {{ states('sensor.livingroom_temp_current_setpoint', with_unit=True) }}"
