Hi everyone,
I’ve been monitoring the home assistant and enphase forums, and it would seem a lot of people got their firmware automatically upgraded recently, myself included.
I looked at the code on a few integrations and noticed they all pulled data from https://envoy.local/production.json
From my testing of this URL, it can take anywhere from 400ms to 2000ms for the envoy to generate this json file. I suspect this may be due to the envoy having to perform some calculations every time this url is requested.
This caused me to look for alternatives which led me to https://envoy.local/ivp/meters/readings which from my testing takes on average 50ms to 70ms to respond and offers roughly similar data.
This is where I noticed another thread and decided to do some of my own tweaks.
Here is what I did to get my power sensors back on track.
I removed any existing enphase related integrations (native and/or HACS)
Added my 12 month token to /config/secrets.yaml
enphase_api: "Bearer 408CHARACTERJWT"
Then, back in /config/configuration.yaml, I added these 2 x CT clamp sensors
rest:
- headers:
Authorization: !secret enphase_api
verify_ssl: False
scan_interval: 15
resource: https://envoy.local/ivp/meters/readings
sensor:
- name: "Power Production"
value_template: >
{% set value = value_json[0].activePower | int(0) %}
{% if value <= 5 -%}
0
{% elif is_state('sun.sun','below_horizon') %}
0
{%- else -%}
{{ value }}
{%- endif %}
device_class: power
unit_of_measurement: W
state_class: measurement
icon: mdi:solar-panel
- name: "Power Net"
value_template: "{{ value_json[1].activePower | int(0) }}"
state_class: measurement
device_class: power
unit_of_measurement: W
icon: mdi:transmission-tower
Then once I was happy with those 2 x CT clamp sensors updating every 15 seconds, I was able to use template sensors to do some calculations with them to get the other sensors I needed.
template:
- sensor:
name: Power Consumption
state_class: measurement
icon: mdi:home-lightning-bolt
unit_of_measurement: W
device_class: power
state : >
{{ states('sensor.power_production') | int(0) + states('sensor.power_net') | int(0) }}
- sensor:
name: Power Export
state_class: measurement
icon: mdi:transmission-tower
unit_of_measurement: W
device_class: power
state : >
{{ [0, states('sensor.power_production') | int(0) - states('sensor.power_consumption') | int(0) ] | max }}
- sensor:
name: Power Import
state_class: measurement
icon: mdi:transmission-tower
unit_of_measurement: W
device_class: power
state : >
{{ [0, states('sensor.power_consumption') | int(0) - states('sensor.power_production') | int(0) ] | max }}
Now I have 5 sensors.
The only information currently being extracted from the envoy is the 2 ct clamp sensors power_production and power_net.
The other 3 sensors are template sensors where home assistant performs calculations when the 2 x CT clamp sensors get updated every X seconds.
Now I am able to have a dashboard like this that updates every 15 seconds.
Feel free to try smaller number refresh intervals for yourself if you want.
Or graphs like this
