Hi,

You can use Gurux open source libraries to read the data from the meter.
http://github.com/gurux

There is a lot of data, so I believe that the best way to start is if you download GXDLMSDirector and connect it to your meter.

Hi,

It's doable, but it will take some time and requires some understanding from meter reading.

How you are planning to transport the bytes between the meter and LCD display? 200 meters is so long distance that you can't use RS-232. You need to use RS-485 or a wireless communication channel.

Wired Connection is preferred if it is not possible for 200mtr the, lets go for wireless.
Please give me some technical help in this..

Hi,

You need to check if your meter supports RS-485 or Wireless communication channels. If it's not, then you need to get RS-232 Wireless converter that you can connect to the meter.

My Energy Meter Supports RS232.
Communication available in my meter - RS 232 / IR / IrDA /RF (2.4 GHz/865-867MHz)

Hi,

RS-232 doesn't work for so long distances, so you can't use it. You Can try with RF. You need RF transmitter and received for your LED controller.

I suggest that first, you try to read the meter using RS-232 and GXDLMSDirector.
Communicating with RF might be really hard and when you have the connection to the meter you will know that it should be possible.
