I implemented switching the coffee machine on and off by means of a relay. It works great. I took a single-channel 5V relay (KY-019), you can use the relay that I suggested above, but it hasn’t arrived yet, and it arrived much earlier than AXICOM IM01 3vdc SMD
I glued the relay itself to the back of the control panel housing, made a divorce for the servo, for esp and for the relay.
I also implemented a water drain to drain water when flushing the coffee machine past the cup, and then you can pour coffee into the cup.
Watch the video how the water drain works and how the full process works, from turning on to making coffee
Connection diagram
You can download the part for printing on a 3d printer here
Important. I designed the hole for the gear for the SG90 Micro Servo. It comes in very tight, but it holds tight and does not jump off. There is no need to expand the hole, just make a good effort when pressing the servo into the hole and the servo will start to enter.
You can set the desired position of the servo to adjust the water discharge. I have set the following values
