Inverter data

Individual inverter data, available for all Envoy models as of firmware 3.9, class EnvoyInverter.

for sn, inv in data.inverters.items():
    print(f'{sn} sn: {inv.serial_number}')
    print(f'{sn} watts: {inv.last_report_watts}')
    print(f'{sn} max watts: {inv.max_report_watts}')
    print(f'{sn} last report: {inv.last_report_date}')
    print(f'{sn} panel output: {inv.dc_voltage}V @ {inv.dc_current}A')
    print(f'{sn} output: {inv.ac_voltage}V @ {inv.ac_current}A {inv.ac_frequency}Hz')
    print(f'{sn} temperature: {inv.temperature}°C')
    print(f'{sn} energy produced: {inv.energy_produced} Wh')
    print(f'{sn} energy produced today: {inv.energy_today} Wh')
    print(f'{sn} lifetime energy produced: {inv.lifetime_energy} Wh')

Note

If the /ivp/pdm/device_data endpoint is not supported by the Envoy firmware, each EnvoyInverter will have None for the detailed attributes: dc_voltage, dc_current, ac_voltage, ac_current, ac_frequency, temperature, energy_produced, energy_today, and lifetime_energy.

Data sources

The data is provided by one of the updaters below, ordered in their probe sequence.

The base data set is identified by the pyenphase.const.SupportedFeatures flag INVERTERS and DETAILED_INVERTERS for inverter details. First updater probe that returns the INVERTERS feature flag will be used.

EnvoyDeviceDataInvertersUpdater

This is the default updater for inverter data. It provides data for individual inverter production data as well as inverter device details. Data is measured/calculated by the Envoy.

endpoint	/ivp/pdm/device_data
json path	[?(@.devName=='pcu')]
data	json node	uom
serial_number	sn
last_report_date	channels[0].lastReading.endDate
last_report_watts	channels[0].watts.now	W

Note

Raw fields for dc/ac voltage/current/frequency are provided in milli‑units (mV, mA, mHz) by the endpoint and are converted to V/A/Hz by the model.

EnvoyApiV1ProductionInvertersUpdater

This is the updater for base inverter data. It only provides data for individual inverter production data. Data is measured/calculated by the Envoy.
