Enphase Envoy Sensor Platform Broken on certain envoy firmwares.

[mondomx]

Home Assistant release with the issue:

Home Assistant 0.104.0

Last working Home Assistant release (if known): Unknown

Operating environment (Hass.io/Docker/Windows/etc.):

Hassio running Docker on Ubuntu 18.04

Integration:

https://www.home-assistant.io/integrations/enphase_envoy/

Description of problem:

First, the sensor.py spits a python error gathering states from the /api/v1/production/inverters API. Included traceback for debugging.

Second, the Integration seems to be scraping the data from http://envoy/production.json URL and not the http://envoy/api/v1/production URL available on envoy firmware R4.10.35 (6ed292).

The data contained on the production.json is wrong in the R4.10.35 (6ed292) firmware, returning incorrect values when compared to the values obtained in the http://envoy/api/v1/production URL

Production.json.

      "wNow": 716.052,
      "whToday": 95.928,
      "whLastSevenDays": 95.928,
      "whLifetime": 1543.928,

/api/v1/production

      "wattsNow": 688
      "wattHoursToday": 2778,
      "wattHoursSevenDays": 111345,
      "wattHoursLifetime": 121601,

As you can see the values for wNow, whToday, whLastSevenDays and whLifetime do not match the ones on the production API (that the enphase smartphone app shows). So the correct values should be scraped from the /api/v1/production API

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

  - platform: enphase_envoy
    name: Solar Panels
    ip_address: (IP_ADDRESS)
    monitored_conditions:
      - production

      - seven_days_production
      - lifetime_production
      - inverters
