Reddit reviews SMAKN 433Mhz Rf Transmitter and Receiver Link Kit for Arduino/Arm/McU

This is the exact one I have.

For a complete Bill of Materials and guide to setting it up, you can check it out over on Tim Leland's site.

I got exactly what you're talking about running yesterday.

I followed this tutorial, although I ended up hooking it up to Home Assistant instead of the basic front-end provided.

In short - Raspberry Pi + RF433 transmitter/receivers + your plugs.


Sniff the RF codes, then have a local network page that sends out the on/off codes to the plugs through the pi and transmitters.


Feel free to message me if you get stuck or need more detail, some of it I found slightly fiddly and not terribly well explained. Raspberry Pi pinouts here, you can use the 5V pins to power the transmitters on a breadboard.

It was the SMAKN® 433Mhz Rf Transmitter and Receiver Link Kit for Arduino/Arm/McU. (Its just over $6 now)

You can find it here:

Still have not gotten this thing working yet :(

I am using these and rc-switch

I've played with the NRF2401s and the ESP8266, and they're awesome but (personal preference) the easiest way to just click and execute are these.

None of that is exactly decided on yet. We were testing with a 433Mhz rf transmitter and receiver like this.

We are logging the data as well, this is an additional project with the goal of getting live updates and displaying them.

Like this?

I see it has a data pin, but how does it know what data to send if you can't hook it up to a computer to program it?

edit: Didn't see that the link I gave you was a Rx/Tx made for arduino.

Still, can it be used in your method with a door bell button?

I am controlling wireless sockets with my pi and a 433 MHz transmitter and it works flawlessly, so might be worth a thought

If you are looking into wiring them to the gpio pins, you have to make sure you find a dedicated relais that is able to switch the voltage and current and can be used with the pi. But please be careful when handling those. Don't just cut the cable and drill and place the wires into the relais. Use something like this to make sure you get a good contact. You are dealing with a lot of power afterall.

Sorry, English is not my first language :D

Don't know if this counts as "good" but I put together a nodemcu and an RF receiver that transmits the codes over MQTT to my raspberry pi. NodeMCU ~$9 https://www.amazon.com/dp/B010O1G1ES/ref=cm_sw_r_cp_apa_3t7.zbNNKST99 and RF receiver ~$7 https://www.amazon.com/dp/B00M2CUALS/ref=cm_sw_r_cp_apa_bx7.zbPBPEM90

Just noticed you said 345mhz... these receivers are made for 433mhz but you might be able to find a similar one for 345mhz?

Let me know if you want any more details.
