+set a fixed IP for one or more inverters like the example, or let the script do a auto-scan:
+```
+[logger]
+# ip,sn,ip,sn,ip,sn or auto
+# IP address of your inverter(s) data logger and S/N of the wifi kit(s)
+#gateways = 192.168.1.10,602123456, 192.168.1.11,602987654
+# Automatically detect logger(s) on the local network
+gateways = auto
+# Default for the Wifi module/logger/gateway
+port = 8899
+# time to wait for inverter logger response
+timeout = 3
+```
