Configured my ESPHome with MCP2515 CAN-Bus for Stiebel Eltron heating pump

hey,

did not have the opportunity to test the automations (want to be at home for this), but had some time to work on the schematics.

I don’t want to hijack your thread with this, so I created a separate thread for the ESP32 CAN PCB here:

PCB design: ESP32 to CAN supporting ESPHome / Matter

Last update: 2023-04-10 I started to create a PCB to control my heatpump via CAN-bus, basically for this ESPHome project. After seeing many posts regarding how to properly connect hardware (and of course doing this with jumper wires), I decided to go more public with my design - maybe it will help others. While drawing the schematics, I realized, that the design is not limited to heatpumps. The design can be used for controlling / monitoring every / generic CAN-attached device. Current state…
