-WattmonMEGA has two ways of connecting to the Internet. The built-in 100 Mbps LAN can be connected directly to a laptop or router, and is used for setup and local monitoring (but can also be used for remote monitoring if the site has an Internet connection). The USB Host port works with a selected number of USB Cellular dongles (GPRS, 3G and 4G LTE), allowing both outbound and inbound data via the Internet. Although we provide instructions on configuring your local dongle, not all of them work. Need a compatible USB dongle for remote monitoring? Use one of our Huawei dongles, the [[hardware:accessories:E3531]] or [[hardware:accessories:E3372]].+WattmonMEGA has two ways of connecting to the Internet.

 An [[how_tos:serial_port_programming|RS-232 serial port]] allows you to interface with Inverters or other devices that can provide data. Drivers for Delta, Schneider, Studer and Victron inverters are now provided along with the [[hardware:wattmons|Wattmon]], making it simple to remotely monitor your PV panels and energy information from the inverter itself.  An [[how_tos:serial_port_programming|RS-232 serial port]] allows you to interface with Inverters or other devices that can provide data.

 An industry compliant RS-485 Modbus RTU interface is built in and the [[hardware:wattmons|Wattmon]] acts as a Modbus master to collect data from various devices such as inverters, power meters, current sensors, etc. Up to 8 Modbus RTU-compliant slave devices and 10 Modbus TCP devices can be daisy-chained to the interface, and the Modbus can be configured for any baud rate up to 115200 with different parity settings as required. An industry compliant RS-485 Modbus RTU interface is built in and the [[hardware:wattmons|Wattmon]] acts as a Modbus master to collect data from various devices such as inverters, power meters, current sensors, etc. Up to 8 Modbus RTU-compliant slave devices and 10 Modbus TCP devices can be daisy-chained to the interface, and the Modbus can be configured for any baud rate up to 115200 with different parity settings as required.

-WattmonMEGA has a Dallas OneWire bus that allows for DS18B20 temperature sensors to be connected. This can be used for ambient or battery temperature measurement. You can connect up to 8 sensors per device. See here for more informationhttp://wattmon.com/9-user-guide/113-onewire-temperature-sensor+WattmonMEGA has a Dallas OneWire bus that allows for DS18B20 temperature sensors to be connected.
