-Trying to program the Sonoff Pow [comrade MySKU](http://mysku.ru/blog/china-stores/45762.html) learned the hard way how to brick it.
+## Serial Connection
-
-As the Sonoff Pow power monitoring hardware connects AC power to the logic ground of the ESP8266 it is utterly mandatory to **NOT CONNECT AC POWER WHILE SERIAL CONNECTION IS BEING USED**.
+
-During both AC connection and Serial connection you may connect the life AC wire with your PC's DC ground leading to a power short, broken Sonoff Pow and laptop Power Supply as MySKU has experienced.
+Please see the [Hardware Preparation](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation) page for general instructions.
-A solution that works for me is shown in the schematic below using two opto couplers seperating the AC connection on the **left** from the low voltage connection on the **right**. This allows for serial control at 115200 baud and uploading of firmware up to 57600 baud while AC is connected.
-
+As always, you need to access the serial interface. 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.

I used the following procedure to calibrate.
1. Prerequisites
- - Calibrated multimeter ;-)
- - Optional calibrated power meter ;-)
+ - Calibrated multimeter :wink:
+ - Optional calibrated power meter :wink:
- 60W light bulb
2. Connect the Pow to the optional power meter.
3. Connect the 60W light bulb
