**The GPIOs on the Pow might be connected to AC power**, therefore it is not possible to add sensors to the Pow.
**The AC connection between Pow and Pow R2 is different**, so be careful when you perform an in-place replacement.
- Pow R2: Lo-E-E-Li-N-N = LineOut-EarthOut-EarthIn-LineIn-NeutralOut-NeutralIn
- Pow: Lo-E-E-N-N-Li = LineOut-EarthOut-EarthIn-NeutralOut-NeutralIn-LineIn

Please see the [Hardware Preparation](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation) page for general instructions.
As always, you need to access the serial interface.
- Pow R2: The **four serial pins** (VDD, E-RX, E-TX, GND) are available at the rear/short end of the PCB. Do not use I04 and I05.
- Pow: The **four serial pins** (3V3, Rx, Tx, GND) are available at the rear/short end of the PCB as can be seen in the upper part of the image to the right.

## Calibration
Sonoff Pow might need calibration as correct measurements are influenced by hardware and timing differences.
