    • RE: IEC 62056-21 Energy meter

      Yes I have it working.
      Just send the commands "/?!<CR><LF>" and "<ACK>050<CR><LF>" and read the response back.
      I used the left part of schematic and connected the RX and TX directly to the atmega328.

      @electrik my meter don't have a physical communication port, so I have to use the optic interface

    • RE: Energy meter with two tariffs

      Thanks.
      I use a MQTT gateway between the node and the domoticz.
      It seems that I have no choice than create two childs, one for each tariff.

      I have the same question.
      How to display two tarifs?

    • RE: IEC 62056-21 Energy meter

      I have almost working this communication.

      Comercial optical probes like this are expensive:
      Optical probe

      So I build a optical probe based on this schematic
      DIY 62056-21 optical probe

      Communication protocol tested on my meter:

      Baudrate: 300 bps, 7 bits, parity even, 1 stop bit
      Send:     /?!<CR><LF>         (wake-up and sign-on)
      Receive:  /XXX5YYYYY<CR><LF>  (XXX is the manufacturer ID; YYYYY is the meter ID; 5 is the new baudrate = 9600 bps)
      Send:     <ACK>050<CR><LF>    (send ack; reading mode)
      Baudrate: 9600 bps, 7 bits, parity even, 1 stop bit
      Received: C.1(201236731.0(01:39 25-08-18)
                1.8.1(0004398506*Wh)
                1.8.2(0000000000*Wh)
                1.8.3(0008198809*Wh)
                1.8.4(0000000000*Wh)
                1.8.5(0000000000*Wh)
                1.8(0012597315*Wh)
                2.8(0000000000*Wh)
                !
                D
      

      Now I only have to parse the values of tarif 1 (1.8.1), tarif 3 (1.8.3), and total (1.8)

    • RE: Linux gateway don't receive Ack

      Ok, I understand now that the modules are measuring the noise signal strenght before sending someting.
      Apparently the noise level is high, but with the other gateway I get low values.
      It seems to be the linux gateway that is generating the noise ???
      The RFM69 is powered by a separated LDO and capacitors, so I don't think it is a power supply problem.

      The RFM69 linux driver is the same that arduino RFM69 driver? Could be some missing register parameterization?

    • IEC 62056-21 Energy meter

      Hello,
      I'm planning to build a MySensor node to read my energy meter using the optic interface.
      That interface communicates through the protocol IEC62056-21 / IEC1107

      Anyone have already used this procotol?
