Modification Timer, Wifi, manual dose,...

[jopa]

Hello,

my project has reached next step.

It is a modification for the (Mini) Vivaldi II which enables:

• Timer function
• network access (Wifi)
• switching between manual / automatic dose
• power consuption messurement
• shot timer and database

*Edit*
We are working on an english translation of the project documentation here: https://www.kaffeewiki.de/index.php?tit ... creenshots
Everybody is invited to improve translation which started with google translate ;)

Kind regards,
jopa

New software release V1.0 is now public under the known link.

Content:
Some fixes
Webbased switch on with or without boiler
Better raspberry b+ support
Shot database with clean button for uncommented shots
Shots under 8 sec will not be added to shot database, so cups can be heated without database enty
And much more....

[Chura]

Thank you for your work!

Meanwhile project has moved forward and has its own fixed place in kaffee-wiki:
http://www.kaffeewiki.de/index.php?titl ... %C3%A4hler

Functions in actual version V1.03 are:

• programming of the (mini) vivaldi via web interface
• unlimeted timers for switching machine on/off (daily, weekly, single activation) (with/without boiler (non-Mini versions))
• switch on/off via internet with any browser (nice on the way home ;) )
• non-mini versions can be switched on with/without steam boiler
• shot counter and shot database with favourites (automatic and manual)
• switsh on/off of dose automatic
• automatic cleaning function
• simple user interface
• wifi
• automatic power off the machine, when forgotten
• exact time, even after power blackout
• automatically daylight saving time
• switching between manual / automatic dose
• power consuption messurement

[Chura]

amazing stuff, really want to start this project also.
Thanks for you hard work!

Incredible work jopa! Thank you

[Lav]

Thank you Jopa for your exiting project!

My Vivaldi (non Mini) is now running your MyTimer and do it very well. I have installed (as many other S1VII owners) the IKEA Dioder light pods as barista light - this is awesome!

However, I am looking for somewhere in the control unit to switch the light on permanently when GPIO22 goes high for 3 sec. and off when GPIO22 goes high shortly twice.... this would be trivial for a normal on/off switch. Can you help please?

[jopa]

Hello Steffen,

thank you for your feedback.

Also the new feature could be a thought worth.

My first thoughts:
It could be easy, but what happens when machine is switched manually?
When machine is switched off manually, the light will not switch on.
If machine will be switched on, the light does not switch on.

My first idea is to do this without the myTimer. A timer relais should help, which is honnected to the boiler heater.
It switches on, when machine heats. Afer a defined time, if heater is of since 20 minutes delay, light goes off.

A possilbe timer would be: "finder 80.41"
Finder should be available worldwide.

Kind regards, Jopa

Good idea Jopa :) and I would choose the group boiler as it's re-heating with intervals of only 1-2 min, whereas my steam boiler might be switched off...

[Lav]

....It switches on, when machine heats. After a defined time, if heater is of since 20 minutes delay, light goes off...

Do you know if one of the 4 orange relays in the Vivaldi control unit will trigger the group boiler?
I can hear that one of the relays control the steam boiler (when I push the boiler button it clicks), but as I said in my earlier post I would like NOT to switch the light pods depending on the state of the steam boiler....

[jopa]

Hello Steffen,
i have no wirering diagram availabe and my Vivaldi is closed. I would assume one Relaus should do the job, but it clould also be done by a triac.
It does not matter. You have the connecrors outside the blackbox. If You use a high voltage relais, you can connect there.
The above mentioned Finder relais could do that job.

Kind regards,
JoPa

Any chance you or others would translate that awesome looking guide?

Does it feature a REST API?
Could it perhaps become a future feature?
- it would be nice to be able to read/set settings etc. from perhaps other website projects/apps.

Kind regards,
Lars

I have the Google Translate extension installed in Chrome and it does a great job translating this from German into English. Your mileage may vary with other language translations.

[Lav]

Any chance you or others would translate that awesome looking guide?

You can always contact me Lars - I implemented all features/options except the power sensor. Although I am not fluent in German I managed to decipher all of it

[jopa]

English translation woud be great.If you have a first draw, you can create an english page in the wiki.
For technical details i will make a review.
Maybe this would also be a help for other users.

I am not sure wether al translations in the software are OK. If you have better translations, i can change this.

Kind regards,
Jopa

[Lav]

What I meant was that Lars could contact me and ask - we are both Danes
However, I might give it a shot in English anyway someday soon... I think your work deserves a broader audience

[jopa]

Thank you. If you could help, it would be great. I can also translate some points, but i think this would need a big review ;)

As i see, one function is only documented in german forum and not in the wiki.
I am not sure, if it is interisting for you, but the mytimer has also a build in printer server with airplay.
If you have a printer with network interface, but no airplay, the mytimer makes airplay working with any printer.
Printer needs no physical connection to the Vivaldi. Both have to be in same network.
You can configure it with: http://vivaldi:631

Kind regards,
JoPa

I started wit first translation with help of google translate here: https://www.kaffeewiki.de/index.php?tit ... creenshots

I did first review to the translation. I think it should be understandable.

If a sentence makes no sense or is unclear, please give me also a hint.

Kind regards,

Hi,
the Project looks amazing.
Does this mod works with the vivaldi S1v2 not the mini?
if so what does it include? I have a RPI 1B I can use
Thanks,
Assi

[marcusr]

It seems like I might be late to this party, but I am definitely on-board for this mod. I have a S1 V1, that was manufactured pretty late (i believe) because it has the power circuit board encased in the black box and the longer steam arm. Either way, it seems like a lot of people have had success with this mod and I'm going to give it a shot (no pun intended).

[raddude]

I just bought the raspberry pi 3 B with a 3 relay board. Will the software work for version 3?

[jopa]

I have no pi3, so i can noch check it out.
Pi3 should have the same pins, so i assume it should work.
If not, just spend some €/$ for a pi2.

[raddude]

the pinout is the same, however, I attached a 3 relay board and the associated pins for the relay are now GPIO 26 for relay 1, GPIO 20 for relay 2 and GPIO 21 for relay 3. I can remove the default jumpers and add jumper wires to match your program. I'll do that this week and report back to the forum. I'm so excited trying out the mod and having the ability to start my Vivaldi automatically.

[jopa]

If it is working with your pi3. Please update the wiki for pi3. It will help other users.

[Daniels7]

Add me to the list of those how are very interested in how this is turning out.

I have a late build V1 of the S1 Vivaldi. Being able to turn it on using my iPhone would be wonderful. Any additional programming and logging will be interesting to explore. Being able to set temperature from the iPhone would be ideal... I have not seen if that is possible yet.

[s1guy]

I've just started looking into buying an s1 mini. After seeing the official timer, I started looking around trying to find documentation on how it works and I ran across your project. This looks really awesome! Any chance you would make just the source code available? I'd love to see how things actually work and contribute to features development.

[jopa]

The complete timer is scripted and not compiled sources.
You can just install the timer on an pi and look into the scripts.
There is no ducumentation available, because it was not planned to make the project public. You you have to find out everything by your own.

[s1guy]

Thanks! Do you have the source code on GitHub or some other other version control service? I'd love to poke around at it without downloading and extracting the full image.

[jopa]

No, only the image. It is difficult on guthub, because it is not a simple app. It is a modification also in lan confuguration, special packages and php and python scrips. If you want to modify it, you will find some ideas in the image.

[s1guy]

I just tried to download the image, but was given a not found error message

[chas]

What "image" are you talking about? I am not aware of any images in this entire thread. There is one link to a lengthy German Wiki which Google Translate does a pretty good job of converting. Then there is also a link entitled: http:/vivaldi:631 which is what you use to communicate with the hardware once you have it installed and up and running.

Apologies in advance if there is anything else I am missing.

[jopa]

Hi s1guy,

the link to the image was broken. I fixed it and you can download it now.
You got the passwort via PN.

@Chas
The link to the image is in the mentioned wiki. Thank you for the "pretty good job of converting" - i started with google translate, but had to do a lot of chages after that. So it seems it worked ;) I try to improve my english every day.
The mentioned link http:/vivaldi:631 is not really needed. It is the access for the embedded printserver. Only a nice addon, if a server runs in the coffee machine, it can also care for the printers in the home and give them additional functions eg. airprint. But not needed for making coffee ;)
