Proud of myself. An investment of € 6.29 on AliExpress (sorry) to by an ESP32 and NRF24L01 and few hours of experimenting and some soldering I can now monitor my solar panels!
Big thanks to #OpenDTU

This in a little cardboard box, powered by a USB cable. It now lives in my garage and receives radio signals from the micro inverters and it is connected to my WiFi. It has a very nice web interface but I can (and do) also use an API to retrieve data.
