## Debugging ## Debugging
Debugging the Sonoff Pow is a bit tricky as the serial interface has a **direct connection to one of the AC power lines**. Therefore I designed below schematic which allows for serial monitoring at 115200 baud and uploading of firmware up to 57600 baud while AC is connected. Debugging the Sonoff Pow is a bit tricky as the serial interface has a **direct connection to one of the AC power lines**. I designed below schematic using two opto couplers seperating the AC connection on the **left** from the low voltage connection on the **right** allowing for serial control at 115200 baud and uploading of firmware up to 57600 baud while AC is connected.

- For debugging purposes you can use the serial interface with command ```SerialLog 4``` and the Arduino IDE set to 115200 baud (19200 for Sonoff Dual) and both NL & CR or the web console with command ```WebLog 4```. - For debugging purposes you can use the serial interface with command ```SerialLog 4``` and the Arduino IDE set to 115200 baud (19200 for Sonoff Dual) and both NL & CR or the web console with command ```WebLog 4```.

- To aid in finding the IP address of sonoff the network name will be ```<MQTT_TOPIC>-<last 4 decimal chars of MAC address>```. So the default name is ```sonoff-1234```. Another option is MQTT command ```Status 5```. - To aid in finding the IP address of sonoff the network name will be ```<MQTT_TOPIC>-<last 4 decimal chars of MAC address>```.
