Controle buttons on coffeemachine

jovak89

Hi all,

I own a few nespresso machines and i was wondering of i somehow could connect the buttons to brew me a nice cup of Coffee using pimatic.

I was thinking of using a battery powered (diy) 433mhz switch, but have now idea How i could create this. I would imagine it would need a board with a 433mhz receiver and some parts to trigger a relay of some sort. Any body tried or done this before? I would not like to reinvent the wheel.

For a nice cup of coffee don’t use a Nespresso

You may also have heard of the Nespresso Prodigio which can be controlled via Bluetooth LE - https://www.wired.com/2016/03/nespresso-prodigio/

Here are some links for tampering your Nespresso

Off course, the most fun is the building proces and not the using of such projects. But keep in mind if all the effort is paying off in every usage.
So you have to walk to the kitchen, grab a cup. Put it under the coffeemachine. Take your phone, unlock it. start pimatic, scroll to the appropriate buttons. Push on a button just to see the magic of brewing coffee by the machine in front of you. You could have done exactly the same with the physical byttons on the machine it self.
But such a hack could provide you some time programmed cup of coffee when you put a empty cup under the machine before you go to bed.

In short what you need (how I would approach it):
Use a ESP8266, make sure it has always power even when the machine is off (but plugged in)
Find what to connections are closed when pushing the desired buttons.
Solder 2 wires to the connections
Put a relay between the 2 wires
hook up the relay to the ESP
Write a simple HTTP API command so the ESP will close the relay for 1 second.

Future release : detect physical usage of the buttons to log your coffee usage

One of the comments I like from the arduino thread:

I think you need to add some items to your list:

have robot deliver the coffee

have robot drink the coffee

maybe this here does the job …

thanks all, im going to look into this!

@koffienl - would it be an idea to use your espimatic plugin on the ESP to control the relay?

@koffienl Could be useful to generate insights on how many cups of coffee are made

If you really want to gild the lily you could add a color sensor to the cup holder and detect which flavor is being brewed, then keep track of your supply for each flavor you have in stock, and place an order when you’re running out of stock

@passie Nice. Seems to work well for push buttons and for the coffee machine as advertised in one of the videos.

For classic wall rocker switches you’ll need two of them to turn on and off. It may be a bit difficult to fix the thingy on some of the rocker switch housings when the switch plate is big and only enclosed by a thin frame.

If that is needed, you could have a look at ( in dutch )

With this device you can switch via RF and still use the old classic switch on the wall
