Erwin, that check is incorrect
256 * 256 * 256 * 256 = 0x100000000 (4294967296)
Maximum value for unsigned 32-bit integer is 0xFFFFFFFF (4294967295)

Code:

if event.getvalue() then
 value = grp.getvalue('1/1/1') + 1
 
 -- overflow check
 if value > 0xFFFFFFFF then
   value = 0
 end

 grp.update('1/1/1', value)
end

Hi Admin,

Yes you are right, i add the +1 after validation, so it will never be that value

Sorry (;

BR,
