Reading of ZMF120ACd meters in Sweden
Posted: Monday 16 January 2017 20:41
Since I have a house in Sweden as well, I have fiddled a bit to readout the smart meter my gridcompany (Ellevio / Fortum) installed years ago.
It should be possible to read this meter (the ZMF120ACd) via the optical interface (IEC1107 protocol), but I until now I did not succeed in that. I suspect my Gridcompany disabled the IR communication capabilities of the meter.
Please post if you were able to readout the meter using IEC1107 (or similar), because using IEC1107 to readout meters is prefered to most other methods.
I did succeed to collect the IR pulses the meter transmits via what is supposed to be the optical interface. The meter transmits one IR pulse every WatHour. The module I build holds to to meter using a strong magnet. The meter itself is in no way impacted.
My module generates similar telegrams as the S0PCM modules (sold by smartmeterdashboard.nl) over USB/serial that are supported by Domoticz. So: Now I am able to keep track of the energyconsumption my gridmeter registered (unfortunately not the momentary power) in Domoticz.
If you are interested in using this IRPCM (InfraRed Pulse Counter Module), please let me know.
