Ian Jackson has a Morphy Richards filter coffee machine. It made very good coffee. But the display and firmware were quite annoying.
I’m lazy and wanted to be able to cause coffee to exist from upstairs in bed, without having to make a special trip down just to turn the machine on.
A friend pointed me at a blog post by Andy Bradford, where Andy recounts modifying his coffee machine, adding an ESP8266 and connecting it to his MQTT-based Home Assistant setup.
I looked at the pictures and they looked very similar to my machine. I decided to take a look inside.
Ian used a DigiSpark board with an ATTiny85. One of the GPIOs is connected to an optoisolator, whose output transistor is wired across the UI board’s “on” button.
