Smart - Coffee: Arduino Mega version

Is it possible to use the arduino version without the display and pressure transducer? I'm looking for a solution to replace a Gicar box with heating element safety feature.

I don't know where I would use a 10 core wire in this project. I plan to make a seperate wire to go to each sensor or control. Most only require 4 wires. 5V, GND, signal 1, signal 2

It is a lot of seperate runs but in my opinion, much easier to deal with. Since each sensor and control devices are located in different locations within my machine. If you find different solution, please post.

Thanks, will you use two times the same wire? Because the guy used a 10cores wite but yours is 4-5 cores?

Hey, I have just received my aliexpress order, I just want to point out that the cable cable that you recomend isn’t actually a shielded cable, maybe they changed their product but I just wanted to point it out. Thanks anyway!!

would it be fine if I decided to connect the line to the elemt pump and valve instead of connecting them to the neutral with the relays and ssr?

I have bought about everything that you suggested and the code! ;)

But it was a little bit confusing for some pieces to know which one to order, like the adapter, I took the type 5 because I think that's the one you took for your project because I have the same pressurestat as yours so it should be the same. It was also confusing for the 2 channel SSR because I didn't know if it was the high or the low so I supposed it was the low. Thank you for your time!!!

would this work with an arduino mega 2560, because I would want to add a distance controlled module so that I can start it from far away?

This is bloody amazing, Any way to keep up to date with the ESP 32 development. It would be cool if you could also integrate Home Assistant with this!! Also, I do definitely plan on getting the ESP version. I'm wondering if you could provide a updated list of sensors that I should still be getting? It would be nice to prepare for this version ahead of time and get everything needed. I have a Rocket Espresso Giotto Evoluzione R, I assume this would be compatible as well?

I just purchased and waiting arrival of the Smart Coffee board. In planning my task i noticed the max current on the on board SSR is 10A. Ny machine, an Expobar Office Lever has a 1200 W element. Should i plan on using an external SSR for the heating element. Worried about if any heat sink is on onboard SSR. Yhanks and looking forward to receiving the kit.

Hi Amon

Thought I would let you know I finished the Rancilio Miss Silvia mk3 designing and 3d printing a few new mods including an all in one Group-head cover with combined PID, Group Temp Gauge, LED Lighting & Flashing Red LED's when the water tank gets low.

So I am now going to use your New Software / Hardware for my latest project a Izzo Vivi my2 which was sold to me as good condition? (you got to love eBay Sellers) check this out ( Stress ball not Included )

Great project and just what I too have been contemplating for my 2007 Rocket Giotto Premium plus HX machine. My machine, bought new in 2007, has been faithful and reliable and I recently did a major service and expect another 10years out of her. However, I've been hankering to bring the hardware into the modern era with just such a project.

Anyway, I came here to suggest an option that may have already been mentioned by one or two others here already.

I'd really like to avoid having to drill any extra holes (if at all possible). A way potentially around that is to replace the pressure gauge (one fitted in my case) with an electronic multipurpose one that either has at least one manual button for the espresso profile and/or a touch screen that can be menu oriented where the options really open up to all sorts of possibilities.

Once again, great job and yet another innovation from our Kiwi cousins from across the ditch. 🏆

Hey Schematix this project looks awesome and exactly what I'm after! I have a Bezzera BZ99 with a dead Gicar logic board.

I hope it's not a stupid question, but the BZ99 has two boiler probes, from what I see in this project it utilised only one, would I be correct in assuming it'd still work okay and the controller would just connect to one or the other of my BZ99's probes?

Hi

I have just bought a 2012 Rancilio Miss Silvia (V3) and have been looking around at different PID options. I have already done a PID with other other mods on my first ever machine ( 4 months ago ! ) its a Gaggia Cubika (2006). After looking at a few options I came across your video by chance and think your Smart Coffee would be the best option If its possible. I am a retired Electrical Mechanical Engineer so adding parts to make the Silvia a viable option for your Software / Hardware should not be to much trouble. If you think its possible I am up for a challenge. Just subbed to your YT channel so lots to watch while i wait. Later Garp

This project looks great,

I have a single boiler machine and have a few questions:

• Is there a way to add the extra switch to change the boiler to steam mode?

  
  

• I assume the connection to the switch for the pump when draining hot water from the steam wand is connected to the pump as usual. Is this correct?

  
  

• Is there a possibility to change the screen to a round one, I would like to place the screen where the manometer is now.

Hi,

I've got everything working (except the flow meters, but I'll get there) and all is well on a Lelit Mara. What I'd like to do is something similar to the Mara X, where you have a 3 way switch that sets the temperature range (or kPa in my case). I realise it just needs to poll pin states, but I'm having trouble trying to get it to work. Another one for steam mode would be handy too.

SETTING I: 92°C – balanced, nutty and chocolatey cup (light-roast)

SETTING 0: 90°C – fruity, acidity and smooth cup (mid-roast)

SETTING II: 94°C - bitter and more intensive cup (dark-roast)

Hello, it's very informative but what do you think about this, a lil bit different:

hi there, amazing work! , is it possible to adapt your system to a rocket appartamento ?

Hi mate! thank you for your time and material shared! brilliant! I'm following your project, if is there any new update regarding dual boiler? mine is expobar office Leva. Btw, did you tough the idea of a potentiometer at the lever? (For example, in a rotary pump config, connected with a linear potentiometer 404 at the manual lever) that can be used for flow control. Regards. Heck

Bug report - overall, things are working very well. However, on 2 instances, the boiler over pressurized, causing the over pressure valve to open. I didn't get a look at the kPa on the display, but it must have been below the threshold which is set to 120. After shutting it off, then shutting it on, it went into safe mode. The machine had been on for for maybe 45 minutes or so and I had pulled a couple of shots. Another much less significant bug is that sometimes I have to restart the machine to get the brew lever to engage the pump. This is no big deal. I'm not sure if there is a way to get a log from those instances?

Hi, this is great! I’m ordering parts now but I’m in USA, do I need to order anything differently from your list above?
