`Hello there,
I’m fairly new to home assistant (4weeks in). But i’ve been playing mostly with the esp-home and my raspberry pi pico W. I’ve managed to read out two dallas sensors via 1 wire, and display them on my dashboard.
But now i cant seem to get the spi to work with a thermocouple & max6675 via esp-home. Here is my connection schematic, my yaml code and my log.
Can someone point me in the right direction? I’m not a programmer, most of the stuff i use on the esp is copy-paste-modified from fora and youtube
