i built the world's worst IOT coffee machine

Maybe would great to add small ac-dc converter to the project and put everything into the machine. No wires outside. Video format is nice, I like it :)

omg I am halfway through my project doing the exact same thing XD

That is awesome i never thought of that for a coffee machine with a timer built in.

Awesome!!

Safety warning! ⚠

When selecting a relay, make sure you get one that is rated for the voltage and amperage that is required by the coffee machine, especially if you're on 120V, you may require a relay that can handle more amperage than you would on 230V. Check the wattage on the coffee machine label and divide by your mains voltage to get the amperage.
When wiring the mains wires, I recommend using wire ferrules to make sure they sit securely in the relay screw terminals over a long period of time. Do not screw in bare wires! They may look secure at first but over time it will collapse, and will catch fire.

seems a bit over the top considering you can buy outlet switches with esp8266 compatible modules in them for cheap. You probably spent more on relays than you would have on a wifi outlet switch

Why not using a WiFi-adapter, controlled by phone, to switch the whole coffee machine On or Off. It‘s just Plug‘n Play without any dangerous DIY.

Are you using Linux? If so which distro and version are you using

Not a teapot?

Those wire strippers are awesome what kind are those?

Isn't the ESP32 3.3V?

Nice video but you missed the oportunity to implement RFC 2324 Standard from April fools day 1998.

Your ESP32 is 3.3 volts ;) But it is 5 volt tolerant.

Fun project. I personally tend to avoid things that involve AC. Given that and the simplicity of the coffee maker, with just a single physical switch, I think I'd just add a Smart Outlet and plug the coffee maker into that outlet. The smart outlet is easy to control / automate from my phone or Alexa or Google Home or my Home Assistant setup. What I'd REALLY like to do, is control my toaster oven with an ESP32 (knowing remaining cooking time, etc.). I've settled: for my Microwave and Toaster Oven, I use Contact Sensors on the doors and an outlets what can monitor power (Sonoff S31). This way I can monitor when they start cooking, stop cooking, and know when the door has been opened. If they complete cooking but the door hasn't been opened, it sends a nagging notification via all of my Alexas.

It's a simple matter to make it standards compliant; RFC 2324, "Hypertext Coffee Pot Control Protocol" does exist, after all.

Man made an internet cafe

How did you write the program for that? Is there any reference for it?

Hey man, I saw this and the video about the baby monitor. I am studying computer science and soon I'll have to choose the direction(major?) I want to follow. I was absolutely sure I wanted to do Cyber security but one of my latest courses was Systems Labs which made me consider my options and look towards embedded systems. My question is, what does one need to study, or what courses are needed to acquire the knowledge to do what you did in this video? Thanks

Jokes, I'm trying this at home. P.S.: I have no idea what I'm doing still, bazingo

Love the uncrimped live wires that are sticking out at the end of the video.

Do you know that you've could use optocoupler module instead of relay to silently do the same task and using much less space and much less power to activate it?

this is what i live for, projects like these are the best

damn it dude, just buy a smartplug.

I hacked my trashcan now it can violently open up the lid and scare the sh**t out of people in my house

bro please make more of these

If you want to improve the project try to go in apple shortcuts and make a new shortcut that requests html with GET at that address then u can say the shortcuts name to siri

I achieved this with a power measuring smart plug with esphome and home assistant.
I can control it remotely and
if the power draw drops it will announce that the coffee is ready on all google home speakers in the house.

Have you heard of TP-Link Kasa smart sockets

Nice IoT Project.. .

This dude deadass said “DIY IoT”

ESP32 is 3V3, not 5V. 🤷

Bruh, just attach here BLE module or wifi and i will write iOS/MacOS/Android app for you (with bunch of functionality, metrics etc)

The fact that you did not use Hyper Text Coffee Pot Control Protocol is disappointing and my day has been ruined

You are of no use brother!! 👍

what are you doing ,?

can I get the code

Now you just need the tiniest Raspberry to put inside the frame out of sight and teach the coffee machine to grind fresh beans on the spot.

you need more videos they’re great!

Nuh.... true hacker will added step-motor, that will be on/off switch mannualy. That will be "air" layer between inside and outside security =)))

Mike Boyd did that already :D

Is it possible to link this with ifttt (aka corperete greed)

I like the part where you forget to put water and fresh grounds into the coffee pot and you wake up in the morning with no coffee and then proceed to crack your hot decanter when you try to fill it with cold water.

Just use a smart plug and plug your coffee machine into it and leave the switch on the coffee machine to on, then control it with Siri?

Well you you a NFC tag will trigger the URL to turn ON or Off by just putting your NFC enabled phone on the tag

Use Home Assistant.

BTW a mosfet would have done the job for less money than a relay

You could program a interface for it if you have a android of course.
