Energy vs Power

[Pieter-HA]

Wondering whether the sensor.smartevse_ev_import_active_energy (kWh) should actually have been named sensor.smartevse_ev_import_active_power (kW). That makes it consistent with the value on the EV meter. I understand the implication of such a change, as it needs updating the json response from SmartEVSE-3 as well. So maybe just change the unit of measurement for this sensor in const.py? The unit of measurement is correct in the SmartEVSE's web interface.

I noticed the same, in looking for unified names for mainsmeter and evmeter here the wrong name is chosen. A bit hesitant to break backward compatibility; its easy to overcome in the HA integration, but a lot of home made scripts could break...

Ok, I solved the backwards compat problem by adding ev_export_active_energy and ev_import_active_power to the SmartEVSE firmware (see attachment), and then processing that info correctly in the integration (main branch). active_energy_evmeter.zip

Could you test thoroughly, after flashing this firmware, whether the following info is still correct, both on the LCD, the /settings page, and in HA through the latest main branch of custom_components: -mains_active_imported_energy -mains_active_exported_energy -ev_active_imported_energy -ev_active_exported_energy -ev_active_imported_power -ev_total_kwh -ev_charged_kwh

As said, Im not at my SmartEVSE location so can only test statically...

Results from my test: -mains_active_imported_energy = 0 in webinterface and in ha-integration -mains_active_exported_energy = 0 in webinterface and in ha-integration -ev_active_imported_energy = 0 in webinterface and in ha-integration -ev_active_exported_energy = 0 in webinterface and in ha-integration -ev_active_imported_power = = 0 in webinterface but correct in ha-integration and on LCD -ev_total_kwh = 0 in webinterface and in ha-integration -ev_charged_kwh = 0 in webinterface and LCD and in ha-integration

Ok there must be a problem in the function I isolated to prevent doubling the code; I'll have to test this in situ, few more weeks until I get back to the SmartEVSE location.

Ok the code was working but you might have been too impatient, it will take a few minutes before the values are read off of the modbus. It is implemented now in version 1.0.4, there is a typo in there that prevents ev_import_active_energy and ev_export_active_energy to be read, this is fixed in the main branch and will be in the next release.
