Had trouble locating the SPI pins for this particular ESP32 board. I found this diagram with worked. My other ESP32 boards are of a different kind.

MAX31855	ESP32
VIN	3.3V
3V	NC
GND	GND
DO	MISO GPIO12
CS	CS GPIO27
CLK	CLK GPIO14

If you are doing it with esphome , That shouldn‘t matter much should it? You can basically define the CLK/CS pin as well as MISO MOSI in your config.

It was more identify with pins were SPI on this board. It isn’t like my normal ones and I couldn’t get ESPHome to pickup the sensor. All okay now!

K-type thermometer fitted inside the BBQ. Drilled a small hole to allow me to pass this through and tighten with the securing nut.

I will and a second ambient higher in the lid to give me a low and high point.

Testing passed ✅

Record temperatures table. Including Meater App, Grill thermometer, dial positions, K-type probe.

Additional pictures and tweet.

Considerations. Wifi range. Another probe for higher ambient temperature. Probe connectors. Permanent hook up.

What about a destructive notification that updates every n minutes with the ambient temperature and any timers/food temps if in use.
