Change Unit/Suffix automatic

[victor.back]

Hi.



Is it possible to change this Unit/Suffix automatic it the value is over a specific number?
I run this script in resident and have it to calculate the number thats presented, but then I also need to change Unit/Suffix from kWh to MWh so theres no confusion : )

Is this possible to implement in my script or can´t this be done?

Code:

-- Total power year
r1, r2, r3, r4 = mb:readregisters(505, 4)
if r1 then
  value = r1 * 0x1000000000000 + r2 * 0x100000000 + r3 * 0x10000 + r4
  currentvalue = grp.getvalue('32/1/54')
  if tonumber(currentvalue) ~= value then
    if value >999
      then
      grp.update('32/1/54', value /1000000)
      else
        grp.update('32/1/54', value /1000)
    end
  end
end
