Tasmota SML IR-reader for smartmeters e.g. Hichi

← PV, Battery, Grid, Meter

To be able to read the values of the smart meter for evcc correctly, the IR reader script must be changed so that the following JSON tags are generated:

  • SML as the group name of the read parameters
  • Total_in for the total consumption in KWh (4 decimal places)
  • Total_out for the total feed-in in KWh (4 decimal places)
  • Power_curr for the current consumption or the current feed-in in W (0 decimal places) As an option, phase values are also supported.
  • power_l1, power_l2, power_l3 for the power of the individual phases in W (0 decimal places)
  • voltage_l1, voltage_l2, voltage_l3 for the voltage of the individual phases in V (4 decimal places)
  • current_l1, current_l2, current_l3 for the current of the individual phases in A (4 decimal places)

A corresponding IR reader script looks like this:
