2 calculate the energy_hourly and energy_daily by Home assistant and store all the parameter in InfluxDB

3 garafana ID (13295)

step by step

https://github.com/lewei50/Solar-PV-Monitoring/tree/master/HomeAssistant-InfluxDB-Grafana

Step 1: A bi-directional Wi-Fi energy meter

Such as https://www.home-assistant.io/integrations/iammeter/

Step 2: Calculate the extra parameter by Home Assistant

solariammeter.yaml

Step 3: use InfluxDB for storage of Home Assistant

Replace the Default storage to InfluxDB,Full details of the Home Assistant integration can be found here: https://www.home-assistant.io/components/influxdb/

Step 4: show the data in Garafana

Garafana ID 13295

You need to get the following data from infixdb

inverter_power
feedin_power
load_power
grid_consumption_energy
exported_energy
yield_energy
selfuse_energy
load_energy
self_consumption_rate
grid_consumption_energy_hourly
exported_energy_hourly
yield_energy_hourly
selfuse_energy_hourly
load_energy_hourly
self_consumption_rate_hourly
grid_consumption_energy_daily
