Hue/MQTT/Sonoff T1 (tasmota) sync - more elegant solution?

Configuration
1

I have a question about a Sonoff T1 (with Tasmota) and a Hue bulb and whether I can make my set up more elegant.

Situation:
I want a hue bulb(s) to be switched on/off via alexa, hue app, home assistant, or T1 switch… with the T1 switch being synchronised to the state (so it appears correctly on my wall).

Solution:
The solution I have is using 4 automations.

  • Publish any Hue state changes to MQTT which are picked up by the T1 (one for off, one for on)
  • Respond to any MQTT messages from the T1 switch to update the state of the hue bulb(s)

Bonus:
I’d really like a long press on a T1 switch to give me a dimmed light with the simple tap on to give me full brightness.

Here’s what I have already, any help gratefully received:

I didn’t test these but they should be approximately correct.

- alias: 'light to MQTT'
  trigger:
  - platform: state
    entity_id: light.office_light
  action:
  - service: mqtt.publish
    data_template:
      topic: sonoff_t1_1/cmnd/power3
      payload: "{{ trigger.to_state.state }}"

- alias: 'MQTT to light'
  trigger:
  - platform: mqtt
    topic: sonoff_t1_1/stat/POWER3
  condition:
  - condition: template
    value_template: "{{ trigger.to_state.state | lower != states('light.office_light') }}"
  action:
  - service_template: "light.turn_{{trigger.to_state.state | lower}}"
    entity_id: light.office_light
