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

Source: https://docs.evcc.io/en/meters/tasmota-sml-ir-reader-for-smartmeters-e-g-hichi

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:
