Hacking of 433 MHz or other RF devices is a human right for makers because these devices usually use proprietary protocols. Today we will reverse-engineer a so-called “professional” weather station from China and enable it to send its data via MQTT. Then we will hack the remote control of our outdoor awning and use an ESP32 to build a fake twin which understands MQTT. We will use a Raspberry Pi and Software Defined Radio (SDR). You will be astonished how professional this will get.

Well, my brand new 16gig micro SD card came today. Just downloaded the image file and it doesn't fit on a 16gig card. Oh no! Does the software really take up 16gig or is there lots of space on the image? If a lot of space, can anyone point me in the right direction to reduce the image size just a little to enable it to fit on a 16gig card please. Thank you Martin

@AndreasSpiess 6 лет назад

Not all 16G cards have the exact same size. So yours is probably a few bytes smaller. I do not know how to solve it other than start from scratch with Frank‘s script or use a bigger card

@ronstarmk 6 лет назад

I'm having the same issue. I'll give Frank's script a shot.

@sausagehider 6 лет назад

Hi Ron, I have now tried 3 different makes of 16gig cards and none of them are big enough. Also, I have used a computer running Linux Mint and tried several methods of shrinking the image including 'Truncate', all have failed. The image appears to be 145meg too big. The same figure on all 3 micro SD cards I have used. The other option I tried was to copy the files to a new card by first setting up the correct partitions on a micro SD card and then copy the files from the image to a boot (Fat32) section and the files to an EXT4 section, but after using root/admin to copy, some of them just refuse to copy over. I am now at a loss of what to do. The actual data in the image is only about 10gig so there is lots of space that can be removed to shrink the image. If you find a way, please share. Thank you Martin

@ronstarmk 6 лет назад

Martin Ellis I just did a fresh Stretch install on my 16gb card. I had a couple of specific sensors I was looking to see information from that were already part of rtl_433, so I used the script referenced above to get it installed and it’s working great. Not sure how we can shrink Andrea’s image down, but thank you for your efforts.

@sausagehider 6 лет назад

Hi Ron (And anyone else), I had another go at reducing the image file size today and this time it was successful. I had to use something called a loopback to get the image into gparted, then resize, then exit the loopback then fdisk it then ..... well you get the picture. Anyway, I halved the image to 7.5gig and I am using it now on my Pi3 to leave this message. The RTL program is running but finding nothing. I do live in the middle of nowhere though. Anyway, if you or anyone would like this reduced image size file, please let me know. Thanks Martin

@bardenegri21 6 лет назад

Great video! I did not know about URH it seems great. For my weather station I did it the caveman way with SDR# recording rf as audio, then looking at it in Audacity and writing it down by hand. For tiny remotes and simple stuff there is the 'rc-switch' arduino library that can decode and reproduce most of them, would have been worth a mention since it's super simple. Also loved the Ave reference at the start :)

@AndreasSpiess 6 лет назад

In the past I also used Audacity. But now it can be completely replaced by URH. So I did not mention it.

0:25 Hacking the remote control of my outdoor awning for adding an anemometer is exactly what I want to do! Mine didn't have one and I've got no idea how much the wind is blowing, so... Thank you, Andreas! But unfortunately, I'm pretty sure my remote control uses rolling code. I inspected it with the oscilloscope and a 433 MHz receiver module (which is much more tedious) and got a different code each time. But I found the manual of the awning's motor and receiver combo and it tells you how to add a new remote control. So if I reset the control (there's a reset button) and then inspect how it's added to the receiver, I might be able to add my own transmitter. Or maybe they use a bad PRNG, which would be able to be easily cracked with the SDR. Just get a few samples and if it isn't a CSPRNG, you'll be able to get the method used and the seeds (and therefore predicting all other values).

@mike95826 6 лет назад

Thanks for the video. I knew about rtl_433 but hadn't heard about Universal Radio Hacker, used to have to use Audacity to capture waveforms. Great find. Just an FYI, I believe that the RFM96 radio that is used for LORA can also be programmed to do OOK and AFSK. What would have to be done is to connect an I/O pin to D2 (not done on most combo boards) and program the RFM96 to OOK mode. So far the RADIOHEAD libraries don't have that implemented but it shouldn't take too much hacking to figure out the configuration file. That would allow you to move the frequency just a little away from the 433.92 standard, as long as the new chosen frequency is still within the unlicensed band for the country of use. That is in one of my up coming projects. I have an Acu-Rite temperature sensor that I was going to use to figure it out but it saved me the time and fell off the tree into the mud and died.

@AndreasSpiess 6 лет назад

You can get much cheaper chips to do OOK on 433. And there you probably would get the library support. Moving away from the frequency is probably easy for our chips, but not for my awning or the weather station...

@nigeljohnson9820 6 лет назад

The problem with 433.92MHz equipment is that there are far too many, resulting in blocking. I was reciently forced to replace my central heating thermostat, because it was regularly jammed in the on state by other devices in the locality. My replacement thermostat still uses 433.92MHz, but has a duplex protocol, ensuring the command message is received and acknowledged. Because of the congestion on this frequency, I think any home made projects using this frequency should use a bi directional protocol. This is particularly important when controlling a motorized device. RF modules to do this are available at very low cost, around £5 to 10.

@AndreasSpiess 6 лет назад

Fortunately this was not the case here :-)

@nigeljohnson9820 6 лет назад

Andreas Spiess my brother and I designed a system to receive the Oregon weather station modules, the earlier ones used OOK am modulated signalling,the later ones are FM. Our system injects the decided signal on to our common CCTV modulator. This displayed the CCTV and the weather information on all the TVs in the house. Unfortunately the modulator is only PAL, not DVB-T. The price of DVB-T (2) are coming down so I should be able to update the system to support newer televisions that only support DVB reception.

@nigeljohnson9820 6 лет назад

Andreas Spiess you may be interested to know that the sky satellite remote control system that uses the red-eye IR receivers, convert the the remote control IR signal to a 7.2MHz OOK modulated signal that can be sent over the aerial coax to remote the s sky receiver in another room. I built a demodulator for this which was used to remote control the CCTV DVR. Unfortunately technology made the system obsolete when we installed a television/radio/ satellite distribution amplifier. The problem is that the red eye transcoders are powered by 12 volts sent through the TV aerial coax. This is not compatible with the voltage control signal used to switch the satelilite LMB.

@dankendell 6 лет назад

Very interersting video! Thanks. :D I was wondering what your observations are on the reliability of the system? I was looking into using MQTT for a grow room controller (not even with 433mhz RF), but I encountered enough glitches (just messages not making it all the way to the end) that I thought I should probably err on the side of caution when it came to the lighting and stick to a local timer. After all, artificial light for plants is literally a life support system! I then began wondering about feeding back so that you know for sure that what you instructed did actually happen. In my case, an LDR for each light would do the trick. When you mentioned the awning possibly being damaged in high winds, it just made me wonder if there was anything in the data along the lines of a message confirming that it had actually been fully retracted?

@AndreasSpiess 6 лет назад

I use MQTT on an RPi zero for a few months for my lab light. No problem and quite stable so far. You can use QOS1 in MQTT if you want to be sure that the message arrives. But you are right, the system has to be stable..

The weather station is off the shelf and it’s data is logged in a database. You could of course replace the electronics of the station to transmit a message directly to the awning.

Your videos are great! I started playing around with RTL-SDR and hunting weather balloons! And I want to ask if you know how to make this with TTGO 433 MHz board (same as used for balloons). And what about recording and playing the signal again just with this board. Thank you for your service to community!

@AndreasSpiess 3 года назад

I once copied a garage door opener on 40MHz. A similar thing could probably be done with a TTGO. But I assume you are on your own to create the code. And also make sure your device does not use an encrypted (rolling) code. Watch also my other 433MHz videos. I built another 433MHz receiver

@thegrubyak 3 года назад

great project, thanks for sharing. is your esp32 battery operated?

@AndreasSpiess 3 года назад

No. It sits inside the house.

@cbm80amiga 6 лет назад

Andreas, there is good library for Arduino RCSwitch, which I used a few years ago to control all my RC sockets with one single Arduino. With one example program you can easily grab codes from existing remotes and then you can use them in your application. I think it should work also with your 433 devices.

@AndreasSpiess 6 лет назад

Do they also work for the ESP?

@cbm80amiga 6 лет назад

I don't know, it was before ESP chips. Maybe somebody already ported it or other one exists.

@AndreasSpiess 6 лет назад

I got another link to an ESPilight library which seems to work. I will give it a try...

@willwho2512 6 лет назад

RCSwitch library works with ESP8266. It might not be able to decode weather station protocol, but works for those cheap fix code remotes.

@jaimemotavaz3999 6 лет назад

I loved to see my Aercus (AKA Fine Offset WH24)finally spit out the measurements. I had tried with RFLink (your video) but it was not recognised . Excellent work. My troubles began with trying to pipe the results to Mosquito (rtf_433 -F json -U etc), got Error:Connection refused. Is node-red in the SD image? I can't figure out.

@AndreasSpiess 4 года назад

Maybe you use the image of the "Ultimate Pi Server". There you find Node-Red and RTL_433

@tamkepa 2 года назад

Great stuff thank you. I am definitely going to try this for my rolla blinds. Do you thing it would work with my car alarm to lock my car at a set time?

@AndreasSpiess 2 года назад

Car remotes (fortunately) use encrypted communication. So they cannot be hacked without high effort.

@foilandwater 3 года назад

Hi Andreas, thank you for the interesting videos. I found your channel recently and I feel like I cannot learn about SDR quickly enough! In the last 2 years I have been building some weather stations which use the Acurite 5-in-1 and a Raspberry Pi with SDR. Needless to say they have been exciting projects for me who is very new to all this stuff... one of the sites which has a weather station using 433mhz is giving me a lot of trouble over the last few months and I have tried troubleshooting everything. My latest theory is that there is another device nearby which transmits on the same 433mhz frequency and blocks the packets on the weather station from reaching the Pi. Now I'm trying to use the Pi + SDR dongle along with gnuradio companion to try and prove my theory and to solve this intermittent problem! I would be so grateful if you had any suggestion to offer me on my quest, thank you!

@AndreasSpiess 3 года назад

I do not think your theory is right. These packets are very short and I have a ton of other sensors without issues on my receiver. From time-to-time they might interfere, but not too often. Maybe you watch my other videos about the topic. There you find a much simpler way to receive 433MHz signals...

@foilandwater 3 года назад

@@AndreasSpiess Thank you for the reply. I do not think it's another sensor that is hogging the same frequency but instead another type of transmitting device that is not build well, or legally. I cannot think of any other reason why the packets will be received from weather sensor to pi every 3 seconds for weeks at a time, and then suddenly stop for extended periods of time.

@et752 5 лет назад

Just finding this video... seems a very interesting topic. Your dongle link is dead by now though. Can you suggest a new one? Would an ATSC dongle work too? (I am in Canada). Tks for your great videos!

@AndreasSpiess 5 лет назад

The second link still worked. I updated the first one. So both should work now.

Amazing video, I have a question, what would be the alternative if I don't want to use RaspberryPi?

@AndreasSpiess 6 лет назад

You can use a Linux box or a windows PC with virtual box. It is in Frank‘s description.

@rommiei 2 года назад

Hi Andreas, this is very helpful. Planning to buy this cheap weather station in Aliexpress and they are still selling it.. Just a quick question.. Is you setup still up and running after more than 3 yrs now? Just little concern on quality.. Want this to integrate to my Home Assistant

@AndreasSpiess 2 года назад

It stopped working a few days ago. So far I do not know why. It is on my bench...

@klassichd10 6 лет назад

Thanks for this great method. It will be helpful if a device is not supported by the RFLink SW running on a MEGA2560.

@AndreasSpiess 6 лет назад

Is the RFlink only running on the Mega? This seems to be quite limiting. I would like it on a ESP32

@klassichd10 6 лет назад

Unfortunately up to now it seems to be limited to the MEGA - as far as I know. But for me it is more or less an intelligent frontend for ioBroker which maintans the datahandling etc. There also exists a Sonoff RF Bridge between 433MHz and Wifi. It costs around 10 EUR and is supported by Tasmota SW system. But up to now I am just using RFLink and ioBroker.

@Sys-Edit0r-1995 5 лет назад

Well for me, since I'm into ham radio and I like weather spotting I would listen to my home weather station's data and pipe it into an APRS station so the data can be shared to other ham stations or to the local National Weather Service office.

@AndreasSpiess 5 лет назад

Good idea. AFAIK you can also share it with some online services if you want.

@UnimatrixYoutube 5 лет назад

Very useful video, thanks. I have a Pi3B but it runs Pihole and I preferably want to run a project similiar like yours side by side with Pihole and I don't want to delete the Pihole/OS config with another image so I guess I'll have to go with HB9FXQ's manual. Any tips before I take this route?

@AndreasSpiess 5 лет назад

Yes

@CortVermin 2 года назад

there are a LOT of 433MHz devices around, but some of them are a little too far away but very nice weather stations. any tips on how to increase the range/placement of the antenna? and thanks a LOT for sharing, these videos are super cool.

@AndreasSpiess 2 года назад

You always can try to build/buy a directional antenna for 433MHz.

@plopprocks 6 лет назад

Awesome! Pity my shutters use indeed a rolling code and I have no idea how to tackle that.

@AndreasSpiess 6 лет назад

Next time spend less ;-) The cheaper seems to be less sophisticated.

@marinehm 3 года назад

Andreas; I just came across this video. I want to know if you can do the same with video transmitters. Specifically back up cameras for your vehicle that come with a dash mount display? I’d like to find a way to discover the frequency of the camera transmitter. Like those little remotes that run of 433 mghz. Is there a standard for this cameras?

@AndreasSpiess 3 года назад

I have no knowledge in this area :-(

@Soggytiri 4 года назад

Love it! Piggy back your neighbours weather station...

@AndreasSpiess 4 года назад

But now I have my own...

@JanicekTrnecka 3 года назад

In fact, several neighbours of mine are having wide variety of weatherstations (and a wide variety of wireless 433/868 devices) ...so I can do comparisons, or I can have a "backup".

@egghead152 6 лет назад

Fantastic as usual! I would love to see some 433mhz videos.

@AndreasSpiess 6 лет назад

You never know... Do you have a good idea for one?

@EliasAbrego 5 лет назад

Andreas Spiess maybe a similar project with Sonoff Bridge RF

@abhinavgolwalkar 6 лет назад

@blazlenko 2 года назад

Hello Andreas! Since you've had this weather station for a while now I'm wondering how happy are you with it? Is it still working and is it somewhat accurate? Very much thinking of buying one! Regards

@AndreasSpiess 2 года назад

Mine stopped delivering values few weeks ago. So far I did not make the analysis of the root cause.

@drfritz142 5 лет назад

Thank you. Very well done.

@AndreasSpiess 5 лет назад

You are welcome!

@drfritz142 5 лет назад

I have one question: I will try to use your method to "hack" my window shutters remote control. The tech specs of the remote claim that it operates on 433.42 ASK. I understand that the classification 433 MHz is for the band of 433 MHz, not the exact frequency, and that 433.42 probably just denotes a channel. But I haven't been successful finding information about setting a channel for 433 receivers or transmitters. Will your method work with a 433 transmitter / receiver? Or am I out of luck?

@AndreasSpiess 5 лет назад

443.42 seems to be a strange frequency. Most simple and cheap transmitters are on 433.92. So you might not get a transmitter. But maybe it is also a typo? Maybe you just try it?

@drfritz142 5 лет назад

Will definitely try it. The Raspi image is on the card and the SDR radio works. Unfortunately, 433.42 is not a type, so we will see. It is about this remote: www.eibmarkt.com/Files/Datenblatt/42FH.pdf.

@ggarza78 4 года назад

Hello Andreas, I am a big fan of you here in Mexico. I made the same hack with the RTL-SDR Dongle and the weather station you are using, and I am uploading the information to Weather Underground, but I have a doubt on the "rain", the information says it is a counter with increments of 0.3mm, do you have more information about it, the displays shows it as a totalization for 1h. Thank you!

@AndreasSpiess 4 года назад

The counter just counts up with each bit of rain and you have to do the calculations (per hour/per day, etc)

@ggarza78 4 года назад

Andreas Spiess Thank you very much! and congratulations for your RU-vid Channel!

@tobi_n 6 лет назад

Would it be possible to use a 433 MHz receiver module instead of the SDR dongle? Since you used a generic module to send your messages, a generic receiver should have been able to do the receiving/sniffing. Then you could omit the use of a Raspberry PI and one ESP32 could do the whole job.

@AndreasSpiess 6 лет назад

This is of course possible. And I will probably go this way later on. But for hacking an SDR is much more versatile, because in the beginning, you do not know anything. Only after hacking you know which 433 receiver chip will do the job (ASK,FSK,PSK for example). And maybe you even do not know the frequency. This one was simple...

@tobi_n 6 лет назад

Thank you for the answer. I didn't even realize that there are differences in the 433MHz modules. After looking around I assume that CC1101 based transceivers are a good choice because they cover a variety of modulations. Cheers!

@masterluu8 6 лет назад

Something to consider though is there's a lot of ready to use software for the RTL based SDR dongles. Using your own 433 MHz receiver you'll likely have to write a lot of tooling yourself.

@diegoteora1051 4 года назад

Hi!! Thank you for all your Video!! How i can read the value of the sensor on wheater station (433 MHz) and send It over LoRa to another ESP 8266?

@AndreasSpiess 4 года назад

I think I showed it in this and in another video. LoRa is something different. In another video, I used an Arduino Mega and an ESP8266 for my 433 MHz project.

@joncurtis9102 3 года назад

Thank you for this very information video ! I have a Bresser 5-in-1 operating over 868 MHz and I am trying to connect to it using an LPRS eRA Connect2Pi Transceiver Dongle. So far no success with the suggestions provided. Is there anything that I am missing ? Thanks again

@AndreasSpiess 3 года назад

I have no idea. I do not know this device. :-(

@stefanomisuraca9240 3 года назад

Hi Andreas, very useful video. I have an unused Pi3B+ which I can recycle for this purpose, does your image work with it? Thanks in advance.

@AndreasSpiess 3 года назад

Then I also used a Pi3. But look also at the Docker video...

@thesimbon 6 лет назад

You may also consider a direct communication from the weather station to the esp32: by adding an RF433 receiver to the esp32 you could get directly the data from weather station without the need of node-red and mqtt (just in case anything happens) but keep them for home automation

@AndreasSpiess 6 лет назад

This is stuff for more work. This protocol is a little more complex. But I will try it.

@thesimbon 6 лет назад

Andreas Spiess I didn't say it is easy :-) but I think it would be worth having 2 systems doing the same thing for increasing reliability (you want to prevent any damage from the wind in any situation)

@AndreasSpiess 6 лет назад

You are absolutely right!

@weatherchaser1166 4 года назад

I'm off to a good start when you use the same weather station I have

@AndreasSpiess 4 года назад

Then it should be an easy project, I think...

@dagg497 5 лет назад

Could this work with Nexa system? Dince they are the largest power outlet/IR sensor/Button maker. I think Nexa uses pairing or rolling codes on different bands...

@AndreasSpiess 5 лет назад

I do not know.

@TonyLehto 5 лет назад

How did you find the exact 433Mhz weather station frequency? If the transmitter sends data infrequently, using urh is a pain..

@AndreasSpiess 5 лет назад

Most of the devices use the same frequency. I do not remember which one. But using SDR you find it easily because you can simultaneously watch a broad frequency band
