KNX physical address check

[Daniel]

Try this, it takes 2 seconds for each group so run it accordingly based on the amount. 

Code:

addrs = {
  ['1/1/2'] = '32/1/1',
  ['1/1/4'] = '32/1/2',
  ['1/1/6'] = '32/1/3',
}

for ia, ga in pairs(addrs) do
grp.read(ia)
os.sleep(2)

-- get time difference between now and last telegram
obj = grp.find(ia)
delta = os.time() - obj.updatetime
 
if delta < 10 then
  grp.checkupdate(ga, true)
else
   grp.checkupdate(ga, false)
end
end
