Landis & gyr infrared energy meter reader

[Sullivan Buchs]

Here is my job for reading energy meter Landis & gyr by infrared Arduino and MySensors.
Work with arduino mega but i have one with software serial work on arduino uno, nano etc. the schematic is on github.

@sullivan-buchs how did you get 7e1 mode on an uno working?
I have some Energy Meters working with Meter-Bus and the IEC1107 protocol. Couldn't find a proper working software lib for serial communication. I solved the problem using the hardware Serial ports on my Mega.

@sullivan-buchs - I've had a look at github but can't find an explanation for how it works. As a newbie to mysensors can you explain how you 'read' the meter?

Hi as the below circuit shows, the sensor read the electricity usage form the meter via IR, the meter have a Ir LED that transmit the usage, this can be picked-up/read with a IR receiver LED/transister. this is via the electrically circuit providing the data to the Arduino, this can if the protocol is correct, convert this to useful data

Hello, please, can you help me edited for my electricity meter? I use Nodemca v3 and IR receiver and transmitter. Trying to use https://raw.githubusercontent.com/prophetmaster/landisgyre350/master/landisgyr no mysensors/landis.ino, but without defining IR TX and RX I can't compile it.

@Sullivan-Buchs thanks for your code, quiet unique piece. The only working one I found!
I changed the hardware a little to use the TX led from the same sensor board.
Sended a pull request, if you prefer to adopt it.
