OpenDTU / AhojDTU Case (Hoymiles) for ESP32 board

thingiverse

This is a casing for an OpenDTU / AhojDTU made from 3 parts. This allows you to read the inverter data of your Hoymiles inverter e.g. for a balcony solar panel.For ordering the right electronic components see pictures. I ordered everthing on Aliexpress.I assembled the housing parts with M3 metal inserts and fitting screws (M3x10).(The bottom plate is dedicatedly only using 3 screws, because of an installation space collision withthe ESP32 board.)The NRF24 module is just fixed by its own antenna and doesn´t require further screws.The ESP32 board requires some small plastic screws that I reused from some old remote control.The display is mounted with M2,5 metal inserts and fitting screws. (from some old electronics)Since only a part of the display is used, I added a black tape to the bottom part for better optics.The housing is designed with an intentional gap between the two parts for a dedicated shadow-line.For documentation see (both variants should be possible, I used OpenDTU):AhojDTU: https://ahoydtu.de/OpenDTU: https://github.com/tbnobody/OpenDTUSince this modelling took quite a lot of time, please consider a small contribution to my Paypal. It would be well appreciated :)Paypal.me/KorbiMuster
