The switch it is definitely an option. TBH, didn’t even think about it, but I don’t mind going through the extra work to add the relays.
Correct, although, if the sensors/status could be integrated, there’s always an option like this one:
That’s correct.
Our Z10 arrived; sadly the SwitchBot motor isn’t strong enough to fully depress the Z10 power switch so your internal relay option looks like the best way to handle remote start.
Well on that front.
I went to add the second relay yesterday. I’m not sure why, but the relay I put on the 5V circuit was no longer causing the circuit to ground out (which is what the button does to signal on/off).
On the upside, with the realization that the main relay de-energizes after a period of time anyways, I ended up only replacing the 120V switch (black switch) with the Shelly. It’s working flawlessly so far. The downside is that this only gives you “turn on” capabilities from HA, but I suspect that will fit the bill for most cases.
Is there a way to use the Shelly relay in parallel with the top panel switch so both options work?
Probably but I didn’t test. I can when I get some free time.
Did I understand correctly that the new model of the coffee machine has updated the protocol? Did you manage to decrypt the protocol? It’s interesting to watch your topic. It will be great if you manage to reverse engineer this model of coffee machine.
Correct.
Definitely not 
…I just managed to decrypt the “app to dongle” IP connectivity (which includes some traffic to the Jura cloud service), but there’s still the higher level obfuscation/encryption being used. I haven’t done much past that.
If I do, that would definitely be a surprise to me . I’ve been in PC/server/network engineering/network security roles my entire working career, but never dabbled in device firmware coding or anything of the sort. I would not hold your breath 
.
If you have patience, perseverance and a strong desire, you can achieve results, and then maybe they will help you. I also started with difficulty and then, when I deciphered almost everything, there was a person who helped me with the code and wrote the complete control of the coffee machine. I’m still grateful to him for that. It’s just a gift of fate. Automatic control of the coffee machine is cool. Getting up in the morning, hot coffee is waiting for you and you do not need to stand and wait for the coffee machine to make coffee. I wish you good luck and success and will follow your topic.
Just for reference, maybe this will be useful to someone. Not long ago there was an integration for controlling a Jura coffee machine via bluetooth. Read all the details here
Has anyone tried to plug in a Bluetooth dongle in the z10 ? I’m curious since both dongles seem to be the same pins.
Yes and it works and also works with the newer Bluetooth integration.
The only thing missing from that is power control so I’m still using the Shelly relay.
Interesting posts guys, Ryan, thanks for starting. Jura’s mentality for user convenience and lack of updates is quite poor. Especially considering they have machines with auto on/off. I’ve taken apart another jura but not the z10 yet. A couple of questions.
Ed, great idea on using the 1 shelly, i wondered the same thing.
I know really nothing about electrical other than the very basic of basics so feel free to throw rocks at me. Great thread.
Having owned this machine for a while now, my take on all this is that the heat up time is so short that it’s really not worth the effort to automate the on/off. You press the button and by the time you’ve got your cup in place and the milk connected the machine is ready.
The top button actuates both of the microswitches.
Sometimes you do things because you can, not because it’s necessarily needed.
Oh I’m super down for that way of looking at it, but what I felt would be required to make it worthwhile automating this would be a) auto refilling of water (the OP pulled this off pretty easily), b) auto-diversion of the automatic rinsing cycling water (someone did a similar rig on another brand of coffee machine), c) ability to fire off a drink from the menu (currently the Z10 bluetooth protocol is yet to be reverse-engineered) d) the dedicated milk chiller.
With all that, you could achieve the dream of leaving a glass under the machine at night and come downstairs in the morning to a prepared flat white, etc.
For me personally without all those elements there’s enough manual work required that taking the machine apart just to be able to turn it on and save the 30 second heat up time isn’t worth it. YMMV!
Hi, just got the Jura Z10 and noticed they changed the software, so the water tank LED is not always on anymore. I would like it to be permanent on, like it is on the Z8 and Z6.
Do one of you guys know where I can tap the 5 watt on the powerboard, so light will go on when the Machine is on?
Thanks a lot 
Random question - I just recieved a Z10 and it’s got this plastic coming out of the back. Any idea what it is?!
Yes, but having your espresso machine turn on in response to motion in the kitchen in the morning is awesome.
here is my contribution to the jura + homeassistant world.
