These meter readers must be capable of reading from multiple manufacturers' meters - that and the fact that GuruX seem to have an open source product advertising such a capability leads me to believe it can be done. DLMS COSEM has different levels of what it allows - all we need is the equivalent of what the hand held meter readers have - to read consumption and some useful other information that seems to be broadcast. I think the Elster meters must be compliant with DLMS COSEM and it was possible to reverse engineer what much of the information comprised of - with documentation I think it could be relatively easy to modify. Reading through the experiences had by those in my earlier links, I'm optimistic that it is not a great leap to take it from Elster specific meter reading to something more general purpose. I would be very interested to hear how you get on with this.įirst post btw. Also the DLMS COSEM object model looks fairly heavy weight.

However I would guess that the meter has an access code for read/write operations, or maybe just for write operations. Theres plenty of Arduino projects using IR communication. To communicate directly to the meter's silicon over IR should be simple. You could always log the pulses at an SD card every 1 minute or 30 mins etc. >500 - indicating the red light on the meter has flashed.

The code is simply an analogRead and triggers a serial transmission when a certain threshold is reached, i.e. Simple maths when you know that the meter pulse rate is 1 imp = 1 Wh. Im measuring the time between each pulse and calculating a rate of energy consumption in kWh. The nano relays this pulse by 434/433Mhz transmitter to another Arduino that has an LCD crystal display. Has anyone any thoughts or knowledge of the above? Hi, I have done something similar using a Nano with simple photoresistor to pick up when the red LED pulses on my home electric meter. I believe they will all comply with the DLMS COSEM (IEC 62056) protocol and so one lot of programming could theoretically converse with all these meters even though from different manufacturers. I have other meters from Landis & Gyr / Ampy monitoring separate circuits which also have an optical port for interrogation and I'd like to find out more about how they can be interrogated. I have a 3 phase meter (the one in the example above is single phase) and I have written to Elster asking them for more information around what they are broadcasting - we'll see what they come back with. I am particularly interested as I have an Elster meter which I understand transmits the information over IrDA once every second.

The implementation falls short of actually a full understanding of the data coming from the meter (which I believe would be possible if the protocol was better understood): I have found one implementation which claims to be open source under GPL2, but I can find no trace of the source: Is anyone working on an implementation of the protocols that could be used on an Arduino? I think that this is the way to go for ongoing and accurate meter reading. These next few links also cross refer (I think) but they are useful in getting an idea of what is possible. Explains more about what the protocol is.

Most meters nowadays have a way in which to interface and obtain this information - often it is by an IrDA device located adjacent to or in the vicinity of the flashing LED used for the pulse counting. Using such a method would allow for the Arduino to poll when it wants information rather than having to use interrupts etc. I have seen a number of projects where an Arduino is used to read a flashing LED to allow consumption information to be compiled but very little about using DLMS COSEM protocols to read potentially more and also more reliably, actual cumulative consumption information at any moment in time.
