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

← Solaire, batterie, réseau, compteurs

Cette page affiche la version nightly. Passez à la version stable.

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:
