@ -41,11 +41,9 @@ I used the following procedure to calibrate.
3. Connect the 60W light bulb
4. Open a webbrowser to Pow showing the main page and another webbrowser showing the Console
5. Turn power on and wait a few seconds for the pow to settle on a stable power reading
6. Verify the power reading with the power meter or expected 60W and if needed change the power offset value with command `PowerCal` (previously `HLWPcal`) starting from 10000. Default value is 12530
7. Verify the voltage reading with the multimeter and if needed change the voltage offset value with command `VoltageCal` (previously `HLWUcal`) starting from 1000. Default value is 1950
8. Verify the current reading with the calculated value of P (step 6) / U (step 7) and if needed change the current offset with command `CurrentCal` (previously `HLWIcal`) starting from 2500. Default value is 3500
As an alternative to steps 6-8, if you have a known load connected (e.g. a 60W bulb on a 240V supply with 250mA current) then you can use `PowerSet 60` (previously `HLWPset 60`), `VoltageSet 240` (previously `HLWUset 240`) and `CurrentSet 250` (previously `HLWIset 250`) to have the Sonoff-Pow auto-calibrate to these values.
6. Verify the power reading with the power meter or expected 60W and if needed change the power offset in W with command `PowerSet 60.0`.
7. Verify the voltage reading with the multimeter and if needed change the voltage offset in V with command `VoltageSet 235.5`.
8. Verify the current reading with the calculated value of P (step 6) / U (step 7) and if needed change the current offset in mA with command `CurrentSet 103.4`.
## Result explanation
The Sonoff Pow can provide Energy, Power, Voltage and Current information in different ways.
