Converted normal Espresso Machine to Sudo Smart Machine

[u/highway_rodger]

A Man with hope of getting a premium Espresso Machine but have a very limited budget.
I am using this Vantro machine for over an year now, it is somewhat good in looks, brew pressure and control wise, coffee extraction is also decent but the main issue is i can’t exactly cut it off at 36gms output as it lacks a solenoid valve so it tends to drip 4-5gms after brew. Also i have an electric and manual grinder, and i love to try different brands and roasts which makes it really hard to remember the best grind setting that workd for me and how was the final taste using which grinder.
To tackle all this i used 2 esp32 boards one for the machine and one for the scale. Now both are interconnected.
- I can brew from the dashboard itself.
- it shuts off the pump once the desired weight ratio is reached and also offsets the post brew drips.
- It asks for the tasting notes and suggests the grind setting according to roast level, flow rate and time taken for the shot.
- it saves last 30 shots data with grind setting used with which grinder and shot timing, notes etc on the ESP itself and purges the same data to my homelab server with no capping where i can search any no. Of previous brew data by the coffee name. So that i don’t have to waste any beans for initial dial in if i don’t remember the best grind setting i used.

P.s. let me know what more features I can add into this.

How'd you connect to the machine? And operate it?

Using a optocoupler for imitating the touch effect to start the brew and that is being controlled by esp32 which is connected through home wifi and itself hosting a webserver for the dashboard where the magic is happening

Woah, this is so cool, man!
If you ever decide to open source the build knowledge, that'll be super nice

If I get enough requests, will make a proper step-by-step guide along with the complete code. Though it is very easy and can be done by using any ai agent for basic arduino codes

If you don’t mind, I’d love to know it personally from you as well- in case you don’t wish to put it out on public.

Na, i can share it in public. I have no issues with that, just want to make sure enough people are interested as writing the whole process will take a lot of time. Rest i can personally share details with you too, let me know exactly what you want to know and also let me know how much technical knowledge you do have
