ESP Home MAX6675 Reading 0.000

Hi, I am trying to set up an MAX6675 on a ESP8266 but all I’m getting back is a reading of 0.0000c.

I’m using the following code -

  miso_pin: GPIO12
  clk_pin: GPIO14

  - platform: max6675
    name: "Stove Flue Temperature"
    cs_pin: GPIO15
    update_interval: 10s

I’m getting the following logs -

Anyone got any idea?

UPDATE - Solved - one of wired connections must have been dicky
