rtl_433 implement [$200]

[schmiernippel]

Implementing rtl_433 would be really nice.Dozens of ISM Sensors are in the neighborhood to be read out,so you have a wheaterstation in your pocket :-)

--- There is a **[$200 open bounty](https://www.bountysource.com/issues/92212604-rtl_433-implement?utm_campaign=plugin&utm_content=tracker%2F182166508&utm_medium=issues&utm_source=github)** on this issue. Add to the bounty at [Bountysource](https://www.bountysource.com/?utm_campaign=plugin&utm_content=tracker%2F182166508&utm_medium=issues&utm_source=github).

What are you actually trying to communicate with rtl_433? I checked the code of rtl_433, the demodulation isn't complex, just FM and AM, which is already implemented in BLE and Analog TV receivers. The problem is there are too many devices to support.

I guess the backers of the bounty could provide samples and tell which devices they think this should support. I think if you click "solve" here https://www.bountysource.com/issues/92212604-rtl_433-implement they will get an email with "somebody started to work on this"

But this is the main reason why this program is so nice because there are so many sensors supportet and frequently new added ! I use rtl_433 mainly for troubleshooting and exploring new weatherstations and temperature sensors(pool, indoor...)

I can try to decode some of the wireless gadgets, but don't have that much time to adapt everything. The weather station you mean is some kind of temp sensors at home? In my country, these kinds of device are using zigbee or wifi. I need to find something else to test.

as i postet here there is a lot of functionality missing in the TPMS monitor, even standard Schrader TPMS are not working fully... with rtl_433 no problem at all so i think such an implementation would be beneficial ...

What kind of recording will benefit you @jamesshao8? I mean, of course people will want "everything" but that will never be possible, so it would be nice maybe to have a TXT to define the devices? (without knowing all the devices, it is difficult to think on a solution)

ALTERNATIVELY make a simple app that works for 2-3 things and write a wiki guide how to add new entries with Universal Radio Hacker+HackRF so everyone could contribute?

[jamesshao8]

I checked the supporting list of rtl_433, but there is no familiar device I can play with. And there is not much youtube video talking about using of rtl_433. I think it can start with some device that is common in China and Europe.

Yes, I do think making example for other's to add is a good idea. That's the benefit of making things open source.

[eried]

Yes 👍 simple app + guide how to add more will get everyone integrating their 433 / (866?) devices.

@helmarw How do you trigger the sensor to send data? I think the sensors are sending data frequently only when the car reaches 80km/h. That's what I am experiencing on the road.

[helmarw]

it needs to reach at least 30kmh not 80 or you send a 125 KHz tone to trigger the device or you have a the Miller Tool 9936 which can send this trigger signal and decode the TPMS bursts. But this is all written in the post i linked 5 posts above... if you dont have either you could build a rig with a motor spinning the sensor at this speed, doesnt need to be in the car nor does it need pressure to work...

[jamesshao8]

This is what in my call. Are you familiar with that? @helmarw

[jamesshao8]

It's strange that I can't found information of TTETP079 from FCC website.

[helmarw]

i found it immediately ;) TTETP079

you have to start search from this page: https://www.fcc.gov/oet/ea/fccid

but i dont know exactly what type of sensor that is. you can search for the number 3641110AK80XA you get some aliexpress but also schrader. if you have an rtl-sdr you can try rtl_433 to find out the exact type

https://github.com/merbanan/rtl_433/blob/master/src/devices/simplisafe.c <-- would it be possible to implement this in Mayhem? I have an env to test it if needed.

[schmiernippel]

Any news on rtl_433 implementation...??

[evilpete]

It would most likely be easiest to add support the rtl_433's bitbuffer call interface and decoder_output_data() hooks. With these plus clear coding templates for importing device code can made this into mostly simple busy work .

Added another bit of $$$ to the bounty. This would be an incredible add-on.

[helmarw]

jupp agreed, I also contributed some $ would really improve the usefulness of this device

[sn0ren]

This would be an awesome addition. I want to contribute to the bounty as well, but is Bountysource safe to use? It seems abandoned and people are saying that the bounties aren't being paid.

Hi! anyone who added money to this bounty, please try to open a dispute on paypal, check -> https://github.com/bountysource/core/issues/1586

[helmarw]

thnx, but that only works if its not older than 180days everyone else will loose the money

[eried]

yeah I know. I dont know if we can contact someone else, I added some money too back then. It is not a big sum, but it is a crappy situation

[helmarw]

jupp, me too, dont think there is much we can do about. if they are insolvent you basically can kiss your money goodby :/
