	I bought a solar power set from the Lidl in Germany for just 200 euros. A decent deal for 370 Wp panels, a microinverter and some mounting brackets.

	The pad on the UART header farthest from the ESP is connected to a large copper plane. With a continuity test from a multimeter I was able to conclude that this is a ground plane. The two middle pins have thin traces leading to the ESP which means that these are the RX/TX lines. The last pad is probably VCC, I did not measure it.

	The board is powered from the DC/solar side. The Lidl Tuya app reports the DC voltage when the sun is hitting the panels, which usually is around 26 volts in slightly overcast weather conditions. The EWAY specs state that the maximum input voltage for this device is 60 volts. Hooking up some probes to the neatly exposed cable connections to a lab power supply with 20V made the board power up.		The board is powered from the DC/solar side.

	Connecting the UART to a USB-dongle gave ASCII output! Hurray! The baudrate is 115200, which is the default for ESP devices.		Connecting the UART to a USB-dongle gave ASCII output! Hurray! The baudrate is 115200, which is the default for ESP devices.
