Dali interface dimming

Have you tried this script?

thanks, that works for me.

I added a resident script for dimming:

Code:

lastDali = 1

for i = 0, lastDali do
 dimObjects = grp.tag('DALI_DIM_'..i)
 for key, object in pairs(dimObjects) do
   dimmer = object.data
   step = bit.band(dimmer, 0x07)

   if step ~= 0 then
     lvObjects = grp.tag('DALI_LV_'..i)
     for key, lvobject in pairs(lvObjects) do
       up = bit.band(dimmer, 0x08) ~= 0
       value = lvobject.data

       if up then
         newvalue = value + 5
       else
         newvalue = value - 5
       end

       -- clamp between 0 and 100
       newvalue = math.min(newvalue, 100)
       newvalue = math.max(newvalue, 0)

       if newvalue ~= value then
         lvobject:write(newvalue)
       end
     end
   end
 end
 
end

os.sleep(0.1)

And i added a script for setting the status

Code:

require('user.dali')
lastDali = 1

for i = 0, lastDali do
 res = dalicmd('internal', 'queryactual', { addrtype = 'short', address = i })
 if res then
   curr = math.floor(res:byte() / 2.54)
   
   -- set target level status
   targetObjects = grp.tag('DALI_SLV_'..i)
   for key, object in pairs(targetObjects) do
     prev = object.data
     if curr ~= prev then
       targetObjects:response(curr)
       end
   end
   
   -- set target on/off status
   targetObjects = grp.tag('DALI_STAT_'..i)
   for key, object in pairs(targetObjects) do
     prev = object.data
     if (curr>0) ~= prev then
       targetObjects:response( curr > 0 )
       end
   end
   
 end
end

os.sleep(0.1)

Next todo is a scene handler for DALI, see other thread
