ESPHome for Home Assistant

- Kamstrup HAN Module P1 (DK-8660):


This is a hardware module that plugs into the Home Area Network (HAN) port of a Kamstrup Omnipower electricity meter.
Its purpose is to make high-resolution metering data available to external devices via a connection (typically RJ12).
This module does not provide power to connected devices, so an external power source is required for any device that plugs into it.


- SlimmeLezer P1 reader WiFi:


This is a "plug and play" P1 reader designed to connect to the P1 port of a smart meter and send data to a home automation system, such as Home Assistant.
It's built for both DSMR 5 and older smart meters. However, older meters might require an external power adapter.
It's pre-loaded with ESPHome code, allowing it to connect to a WiFi network and be added directly to a Home Assistant installation without coding.
