Riden RD60xx modbus dashboard

Gets readings from the power supply into node-red where it can be shown on a web dashboard. It works by polling the serial port with the modbus protocol. The dashboard is visible from http://your-node-red-server:1880/ui.

This is set up easiest by plugging a Raspberry Pi (Zero W) into the front usb port. With the power supply as the only thing plugged in, it appears as /dev/ttyUSB0.

Connecting the serial port causes the power supply to disable panel buttons. Work around this by upgrading to the Unisoft firmware, and then in the Settings tab, enable "Skip keys lock".

Note: this currently only does read operations.

Note: some third-party nodes may appear with blank styling, and not as they appear in the Node-RED Editor.
