Which energy statistic sensors would you like to see?

[JensenNick]

Which energy statistics would you like to see in this package? Let me know below and I'll ad them to this list.

Statistics Sensors under consideration

• Battery efficiency pr. cycle
  Pr. cycle would be pr. last cycle, 7 days, 30 days, 120 days and 365 days. This require data pr. whole cycle. I'm seeing a solution which will require a SQL query and therefore probably be limited to those who use MariaDB or SQL lite.
• "Burn Down Chart" (ROI-chart). The sensor.economy_nri_pv sums up how much you have got in net return, so the information is available, but I would need help to set this up in an Apex Chart.

Statistics Sensors already included

• Self Sufficiency

Name	Description
Energy Self Sufficiency (ts) energy_self_sufficiency_ts	- Attributes calculated selfsufficience daily, weekly, monthly, quarterly and yearly.

• Yield pr. kWp

Name	Description
Energy Yield Total pr kWp (ts) energy_yield_total_pr_kwp_ts	-
Energy Yield #1 pr kWp (ts) energy_yield_1_pr_kwp_ts	-
Energy Yield #2 pr kWp (ts) energy_yield_2_pr_kwp_ts	-

The package includes hourly, daily, weekly, monthly, quarterly and yearly utility meters to track "Yield pr. kWp"

• Price pr. kWh

Name	Description
Price/kWh wo PV (ts) price_kwh_wo_pv_ts	- Attributes include daily, weekly, monthly, quarterly and yearly.
Price/kWh w PV (ts) price_kwh_w_pv_ts	- Attributes include daily, weekly, monthly, quarterly and yearly.
Price/kWh Export (ts) price_kwh_export_ts	- Attributes include daily, weekly, monthly, quarterly and yearly.
Price/kWh Export Yield (ts) price_kwh_export_yield_ts	- Attributes include daily, weekly, monthly, quarterly and yearly.
Price/kWh Export Battery Discharge (ts) price_kwh_export_battery_discharge_ts	- Attributes include daily, weekly, monthly, quarterly and yearly.

• Battery Statistics

Name	Description
Energy Battery Discharge Capacity (ts) energy_battery_Discharge_capacity_ts	Available capacity for discharge, with your current settings
Enegy Battery Charge Grid Capacity (ts) energy_battery_charge_grid_capacity_ts	Available space on your battery for charging over AC. This could come in handy for charging automations
Enegy Battery Charge Yield Capacity (ts) energy_battery_charge_yield_capacity_ts	Available space on your battery for charging yield from your solar PV. This could come in handy for charging automations
Battery Efficiency Total (tt) battery_efficiency_total_tt	The "total" efficiency of your battery, meaning from start of measuring until "now".

Would be awesome to have a "burn down" chart of projected payback time of your PV system. Obviously this metric is best when all production and electricity price data is available historically

@AndersNielsen89 Thank you for your input! I believe you have all the information you need (or at least the information I can help to provide) in the "Huawei Solar PEES package" 🙂. Apart from the information from the sensors you would need the amount of your investment and if it has to be really fancy maybe some financial regulation factor.

The sensor.economy_nri_pv is = the savings + earnings you have compared to what you would otherwise have had to pay for the electricity you have consumed. NRI = Net Return of Investment.

And with regards to the historical data, I hope I've set at state_class: on all the relevant data - this makes sure HA saved the data long term (history). Not as detailed as short term data, but every hour should suffice for most use cases I guess. You could consider setting up InfluxDB + Grafana as well.

How to set this up in an Apex Chart or Grafana is another story. That part does not have my focus right now as my priority is to get the right setup an save the right information.
