-# ahoy
+**Communicate with Hoymiles inverters via radio**. Get actual values like power, current, daily energy and set parameters like the power limit via web interface or MQTT. In this repository you will find different approaches means Hardware / Software to realize the described functionalities.
-Ahoy is a project to bypass the original Hoymiles cloud solution.
-In order to use this project, it is important what the area of ​​​​application looks like.
-With each version it is necessary to have an NRF24L01+.
 
-Click on the link below you are interested in. 
+List of approaches
-There you will find further explanations on how to proceed. (*Note: It is still under construction!*)
