You could possibly adapt the meters of this project http://dmn.kuulalaakeri.org/vnt-lda/ to dispaly live data. There is this version as well http://dmn.kuulalaakeri.org/dmn-edc/ which is more gauge orientated. You will need to do a bit of work to get it all to work but they are good examples to start from.
