Introduction

Variable Energy Prices are not new, but there are only few suppliers .
Since 2023 I am watching the market to get more information and to be able to form an opinion on this subject.

Integration

Smart Home

The open Home Automation Bus (openHAB, pronounced ˈəʊpənˈhæb) is an open source, technology agnostic home automation platform which runs as the center of your smart home! Some of openHAB's strengths are:

1. Its ability to integrate a multitude of other devices and systems. openHAB includes other home automation systems, (smart) devices and other technologies into a single solution
2. To provide a uniform user interface and a common approach to automation rules across the entire system, regardless of the number of manufacturers and sub-systems involved
3. Giving you the most flexible tool available to make almost any home automation wish come true; if you can think it, odds are that you can implement it with openHAB.

OpenHAB stellt (zumindest bis Version 4.0.2) kein spezielles Binding für die Sun2000 zur Verfügung. Was es aber gibt, ist ein Modbus-Binding. Ein eventuelles Sun2000-Binding würde ja auch die Modbus-Schnittstelle nutzen, es könnte eigentlich nur das Handling vereinfachen.
