Abusing Raspberry Pi GPIO pins as a radio transmitter to control my ceiling fan 

This was incredibly interesting. Definitely subscribed.

This was amazing! This may be what I need to finally have a way to remotely control my ceiling fan. I bought an old house from the 70s back in 2007, and its where I still currently live. In my master bedroom is the only ceiling fan in my house that did not come with its remote control. This ceiling fan is a knock off brand ceiling fan, but I have ordered dozens of different ceiling fan remotes for ceiling fans that looked like mine through google searches, and every single one of these remotes did not work with my ceiling fan. The ceiling in my room is also really high, so even though I am 6 Feet tall, I still have to get up on the top of my step ladder in order to pull the chains to change the fan speed, and the chain for light is broken, so I just installed a different light in my room. I kind of gave up after the 12th time I ordered a remote and it failed to work. I already have a bunch of Broadlink devices in my house that I use to capture remote signals, so I can control RF and IR Devices over WiFi using this device, but I have never been able to figure out how to capture the signals my Ceiling fan needs to transmit the correct RF commands to it to change the fan speed or turn on or off the light or fan in it. Do you know of a way to capture the codes needed without having the remote to the ceiling fan by chance? Either way, Awesome Video man! I hope this brings in the subscriber base you deserve, I am subscribed now, and I actually found this through a Toms Hardware article that referenced your video, so hopefully that will direct more traffic your way!

Dude, thanks for this awesome video. I wish there would be more content like this.

"Holy sh**, it worked!" I died XD

Awesome. I had tried to broadcast fm radio with a pi 0, but this is an even better usecase and the software seems to have improved since then as well!

So much useful and interesting info packed into 5 minutes. Thank you!

Fantastic series of videos. I somehow managed to make this work for my Home Depot "Britton" fan controllers... made my Sunday! Thank you!!!

Very cool video, straight to the point with a lot of information in a short time ! Liked & subbed

Fantastic tutorial! This was exactly what I was looking for. I was able to follow your instructions to control an old Radio Shack wireless remote switch using my Raspberry Pi. Believe it or not, without any kind of antenna plugged into the pin, it actually works within a range of up to 2 meters! I'm planning on using this technique to control the fan speed on my humidifier, but first I had to order the optional remote for it so I can eavesdrop on the signals it sends. Thanks for the video!

If anyone is having trouble getting this to work with their fan, pay attention to the pause interval and move the repeat number up to at least 3. These issues tripped me up.

Now, this is epic

Amazing! Exactly what I was looking for.

3:50 no truer words have been spoken 😂😂

Awesome! More raspberry pi please!

Awesome - thanks for the great explanation and detail! Subscribed! Looking forward to your next projects :)

Amazing explanations, love these kinds of videos

I just stopped to watch your video as getting into the Raspy world, and I was amazed. Can I ask if possible to provide the Flask code? Anyway, either way keep up with the work I am hooked now, lol

This is exactly what I need to control my motorized projector... I'm in IT but can't totally write program language, but I can kind of understand and can definitely copy and paste 😅... I hope to also have it tied into Google Assistant

Really inspiring, thank you for this one. :) I would love to learn more about the "web app" you quickly made to test the setup. All the best

Just watched previous video and this one. Very neat and impressive!

Wow! Fantastic! Have you been able to integrate it into Home Assistant as you mentioned on 4:25 ?

Sorry for stating, that any effort to filter out "harmonics" must fail when made this way. The wires for connecting Pi and Filter will radiate probably as much still unfiltered signal than attached antenna will radiate filtered signal - if not more than the antenna.

Awesome video, just discovered your channel through the Valorant video, you definitely deserve more views and subscribers! By the way, could you consider making the HA integration open-source? I have a Bluetooth controller light that also has a RF remote and I think that RF control would be more consistent that Bluetooth

Great work! I want to adapt this to control X10 devices. I guess receiving signals would be asking too much. Thanks

I really want to use the GPIO pins as a wireless transmitter and reciever to network 2 pi's and create an ssh link over the connection. I know its possible but haven't seen it done anywhere.

We loved this project so much that we featured it in this weeks episode of The Electromaker Show! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TDF12MVMOfM.html

earned a new subscriber please make a video on using universal radio hacker

incredible project, i came from reddit 😎

Genius

Many thx...very helpful. I wonder if you made the follow up video you referred to with the home assistant? I searched your channel but could not find it HONESTLY... that is a simple Idea and I am shocked I have not thought about it Do you kow if it is capable of transmitting text? I mean like as packet radio good job man too bad I just noticed your channel cheers from palestine

Hi everyone, I would like to be able to receive the signal from a controller with an HCS301 (MICROCHIP KeeLoq) in the transmitter and with a PICxxx or an ATMELxxx in the receiver. There is a library for ARDUINO about receiving the signal from an HCS301 and another to emit the signal from an HCS301, but I can't find it... I'm still looking. Greetings to all.

where can i find a video on how to connect the matierials (for example that small antenna with the wires, etc...) . i really need help with learning such skills

Genius stuff

What kind of range do you get with the filter + antenna ? Also whats the dbi on the one your using ?

what are you doing as a profession? and how did you learn all this?

Hello, love the videos and I subscribed do you know the code for your web server

Do you know how to connect or attach the raspberry pi GPIO pins to the DWM1000 uwb IC?

How do you power up your antenna? I need a range more than 30 ft…

My raspberry pi 4 crashes when I run the script, it's able to send out a signal and I'm able to turn on some radio controlled lights in backyard, but I have to restart my pi everytime I want to run it. Do you know a fix for this? Love your vids I wish you posted more.

It looks like sendook requires sudo to be run.. were you able to get it to work normally, or did you give www-data sudo rights?

Nice! I'm trying this with my Pi 3b, but I have some trouble getting the "antenna" to stick to the GPIO pin. How did you manage to get that attached without it falling off?

would it be possible to be done for esp32?

The signal I recorded isn't a nice OOK signal. Any way I can send a frequence modulated signal on a carrier signal with rpitx too? (Is there a better support channel for these questions?)

Does the added antenna improve the range of the signal or not?

I cloned rpitx off github, but it doesn't have the sendook util... Did I grab the wrong one?

What range of freq could transmit ?

Does this rpitx works in pi4

So hold on a second, did you just shut off a ceiling fan and regular light, none of which are "Smart" using a Raspberry Pi sending radio frequencies?

Please sens address.
