RESOLVED - Homeassistant.service "light.turnon" not functioning when I dynamically set the white_level using rotary_encoder

after more digging and searching I came across this post which worked a treat with some tweaking.

ESPhomelib, Native API, publish sensor value back

In case anyone ends up on this thread looking for how to publish an increase/decrease in Brighness back to HA , this is what I’ve now got working - the above was a good pointer, but an integer is required.: - homeassistant.service: service: light.turn_on data_template: entity_id: "light.bulb_01_test_light" brightness: "{{ brightness_1 | int }}" variables: brightness_1: 'return id(bulb_01_test_light_bright).state + 5;'
