 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 information: http://wattmon.com/9-user-guide/113-onewire-temperature-sensor+WattmonMEGA has a Dallas OneWire bus that allows for DS18B20 temperature sensors to be connected.
