Hi.

Is it possible to write this if condition in a modbus profile for automatic scale the values dependent on how big it is, for easier reading it? 

Code:

-- Total power ever r1, r2, r3, r4 = mb:readregisters(509, 4) if r1 then   value = r1 * 0x1000000000000 + r2 * 0x100000000 + r3 * 0x10000 + r4   currentvalue = grp.getvalue('32/1/55')   if tonumber(currentvalue) ~= value then     if value > 999999999 then         units = 'GWh'           value = value / 1000000000     elseif value > 999999 then           units = 'MWh'           value = value / 1000000         else           units = 'KWh'           value = value / 1000         end         value = string.format('%.2f', value) .. units         grp.checkupdate('32/1/55', value)   end end
