Support for PZEM 004T Energy monitor

[TD-er]

What do you mean?

This sensor is using the (Hardware) serial port, so you must uncheck "Enable Serial port:" on the Tools->Advanced page.
This does make sure no logs are sent to the serial port and also any incomming data is not interpreted as commands and thus allows exclusive access to the serial port for the plugin.

I have kept the settings as it is and still receiving accurate readings.
