+=== UART + Wanderer ===
+In motioneyeOS things are a bit different:
+For activating the UART raspberry pi zero w port:
+Edit /boot/config.txt
+Add this:
+  dtoverlay = miniuart-bt
+/dev/ttyAMA0 existed before but it doesn't work by default. After activiting miniuart-bt it starts working
+With this configuration two uart units are activated
+Bluetooth is not necessary to be disabled. Apparently it is already disabled on MotionEyeOS. Also the console is not redirected to the serial.
+Test with a loopback cable between tx and rx and with this test program:
+  import serial
+  test_string = "Test serial port ...".encode('utf-8')
+  port_list = ["/dev/ttyAMA0","/dev/ttyAMA0","/dev/ttyS0","/dev/ttyS"]
+  for port in port_list:
+    try:
+      serialPort = serial.Serial(port, 9600, timeout = 2)
+      print ("Serial port", port, " ready for test :")
+      bytes_sent = serialPort.write(test_string)
+      print ("Sended", bytes_sent, "byte")
+      loopback = serialPort.read(bytes_sent)
+      if loopback == test_string:
+        print ("Received ",len(loopback), "bytes. Port", port,"is OK ! \n")
+      else:
+        print ("Received incorrect data:", loopback, "on serial part", port, "loopback \n")
+      serialPort.close()
+    except IOError:
+      print ("Error on", port,"\n")
+== Wanderer ==
+For the serial connection to the wanderer we used:
+https://github.com/rosswarren/renogymodbus
+It must be converted to python2 along with several dependencies
+It works!
