Hi @tilz0R
Like you, I use this blueprint or the automation Zigbee2MQTT - Philips Hue Tap Dial Switch by SmartHomeGeeks.io
and would also like to adapt its MQTT section for the Dimmer Switch, as you suggested.
However, already in tap dial automation I come across warning messages in the HA log after a restart when I deactivate (in preparation for zigbee2mqtt 2.0) the homeassistant legacy_triggers in z2m. For example:
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ trigger.payload_json.action is match('^button_[1-4]_press$') }}'
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ trigger.payload_json.action is match('button_[1-4]_press_release') and states(counter_var) > '1' }}'
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ trigger.payload_json.action is match('button_[1-4]_press_release') }}'
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ states(input_text_var) == '3' and trigger.payload_json.action is match('^dial_rotate_') }}'
It affects all template lines that contain trigger.payload_json.action
