Integrate with Home Assistant

Using (aggregated) meter values is most effective when some energy devices at home can be controlled according to a plan. Home Assistant provides support for some of energy devices, and it also has integrations for reading the P1 port and to fetch dynamic (hourly) energy prices.

The first step for integration with Home Assistant is to use the P1 data as captured by Home Assistant, see e.g. https://www.home-assistant.io/integrations/p1_monitor/ with source code here: https://github.com/home-assistant/core/tree/dev/homeassistant/components/p1_monitor

A second step is to make the aggregated values available to Home Assistant for display, similar to the display by Home Assistant of data from the P1 port.

A third step is to use dynamic energy prices, for example the hourly prices from the EnergyZero platform by https://www.home-assistant.io/integrations/energyzero/
