Worked well and is now installed inside the coffee machine connected to a PiicoW which alerts me to water low or temperature too high (TMP117) - via web page, email and buzzer. It is connected to a PiicoDev button for installation convenience daisy chained to the temperature sensor

Very easy to use, worked straight out of the box. I found I2C much easier to use than SPI. I like the option of a top or side mounted connector, smart thinking by the designer. The mounting holes, being outside of the area of the display make them easier to utilise.
