Hue Brightness feedback

[Erwin van der Zwart]

Hi,

Try this: (I added a check to be sure the device supports BR, CT or XY)

Code:

-- Set name (Lookup in HUE app under light configuration) and feedback adresses (don't change statevalue, brivalue and colorvalue as they are used as memoryfield)
addressmapping = {
  -- Name                  -- On/Off FB       -- Bright FB   -- Color FB
  ['Schlafzimmer'] = {state = '10/1/27', bri = '10/1/15',  rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Laura Wand Links'] = {state = '32/1/7', bri = '32/1/9', rgb = '32/1/16', statevalue = '', brivalue = '', colorvalue = ''},
  ['Laura Wand Rechts'] = {state = '32/1/8', bri = '32/1/10', rgb = '', statevalue = '', brivalue = '', colorvalue = ''},
  ['Küche Led'] = {state = '32/1/11', bri = '32/1/13', rgb = '10/1/5', statevalue = '', brivalue = '', colorvalue = ''},
  ['Küche indirekt'] = {state = '32/1/12', bri = '10/1/3', rgb = '32/1/14', statevalue = '', brivalue = '', colorvalue = ''},
  ['Esstisch'] = {state = '10/1/157', bri = '10/1/159', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Laura Zelt'] = {state = '10/1/25', bri = 'x/x/x', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Wohnzimmer Links'] = {state = '32/1/3', bri = '32/1/5', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Wohnzimmer Rechts'] = {state = '32/1/4', bri = '32/1/6', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Kinderzimmer Links'] = {state = '32/1/17', bri = '32/1/19', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Kinderzimmer Rechts'] = {state = '32/1/18', bri = '32/1/20', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''},
  ['Küche Theke'] = {state = '10/1/161', bri = '10/1/163', rgb = 'x/x/x', statevalue = '', brivalue = '', colorvalue = ''}
