So did u manage to figure out the software bud?

So I got my device and installed as per your instructions. However when I run sudo rtl_433 -F json -G | mosquitto_pub -t outdoor/rtl_433 -l -h 192.168.0.8

I get connection refused. Here is my log:

Any ideas ?

Do you have authentication enabled on your MQTT broker?
Might need to add -u -P to the command for username & password, respectively.
So:

sudo rtl_433 -F json -G | mosquitto_pub -t outdoor/rtl_433 -l -h 192.168.0.8 -u user -P pass

Also, if you run this, by itself, what do you see?

sudo rtl_433 -F json -G

bachoo786 · October 4, 2017, 10:47pm

Right it was the username and password needed. However it runs well but when I transmit a rf signal from my remote it doesn’t pick it up (the transmitted code) which is very surprising. Do you experience that?or am I doing something wrong?

xstrex · October 5, 2017, 1:39pm

You’ll probably have to do a little troubleshooting to figure this out. Try running:

rtl_433 -G

It won’t pipe to MQTT, but it will try and decode all known signals.
If that doesn’t work, check to see if your device is in the “supported device protocols” table, on the github page.

If that still doesn’t work, you might have to work on adding your device, to the supported devices. See the “Supporting Additional Devices and Test Data” section on the github page.

OK so my DVB-T dongle arrived from china… complete with crappy aerial and remote control
Turns out its a FC0012 tuner model.
I’ve connected it to my x86 ESXi server and passed the USB through to an Ubuntu 16.04 VM (this one happens to be also running docker + hass.io).
I needed to blacklist the DVB kernel modules to get rtl_433 working.

But I have problems…

Firstly I cannot receive and decode the signals from a known supported device (protocol [44] “CurrentCost Current Sensor”).
When running rtl_433 -a I can see a periodic packet every 6 seconds, which is what I expect from the current cost… but its not decoded when running with rtl_433 -R 44 - I just see nothing.

Secondly whenever rtl_433 quits it seems to leave the USB device in a non-functioning state, and I need to pull and re-insert the dongle. If I don’t do this then next time I run rtl_433 it exits as soon as it calls out to rtl_sdr - i.e. pretty much immediately. Weirdly this seems to be related to the version of rtl_433/rtl_sdr being run - when I ran an out of date version of rtl_433 from docker (https://hub.docker.com/r/sysrun/rtl_433/) it didn’t have the same issues…

I also tried with very latest versions with a new docker image I forked from here:
https://hub.docker.com/r/hijinx/rtl433test/
The latest version has support for more devices, but exhibits this “only works on 1st execution” issue…
(BTW I also compiled and ran rtl_433 directly on the ubuntu vm with same result)

Is it my cheap and crappy dongle? Should I try with a device from reputable (and more expensive) brand?
Or do I need to fiddle about with any of the tuner parameters? (and if so, how to I find out what?)

hijinx · October 11, 2017, 5:07pm

Haha. Issue #1 was a simple thing…

Just needed to correct the tuning offset by finding the ppm value per these great instructions:

Yes. I am a SDR noob

Still having issue #2

hijinx · October 15, 2017, 10:06pm

Got it working in the end, by using someone’s docker image with an out-of-date version of rtl_433:

The only info I get from the current cost is current usage in W every 6 seconds:

bachoo786 · October 15, 2017, 10:08pm

I bought the current cost and now thinking of returning it as I had the same issues as you mentioned in your previous posts.

hijinx · October 15, 2017, 10:34pm

My problem is more with the rtl dongle I think… it’s weird that it works great with an old version of rtlsdr and rtl433, but if I use latest rtlsdr and compile rtl433 from source it’s working only 1st time I run them never again until I pull and reinsert the dongle.

What rtl dongle (with which tuner) are you using?

bachoo786 · October 16, 2017, 7:08am

Realtek RTL2838UHIDIR is what I use.

hijinx · October 17, 2017, 8:39am

If you’re running docker feel free to try my CurrentCost rtl_433 to MQTT image:

https://hub.docker.com/r/hijinx/currentcost_rtl433/

Note that this image hardcodes the tuner offset ppm (rtl_433 -p switch) to the offset for my tuner.
If you need to change this you can fork my repo and change the rtl2mqtt.sh script to update the ppm value or remove the -p switch and get docker hub to build you a custom image.

Ultimately I hope that the problems I have with rtl_433 crashing with new version are due to my cheap and crappy tuner rather than the software. I have another tuner on order to check this. If that one works well I’ll update the rtl_433 docker to be a hass.io addon…

hijinx · October 29, 2017, 11:03pm

I found the problem - it was a bug in rtl_433 that I have squashed
Now updated as a hass.io addon:

Hi !

If I have 3 sensors for my 2gigs alarm system that are on 433mhz, do I have to synchronize them with the usb key ? How does it know that it’s a door sensor or a movement sensor ?

Thanks !

Hi, sorry to rewamp such an old 3ad.
Is this graph coming from OWL’s data?
TIA

badgerhome · October 29, 2018, 11:22pm

Graph is generated from OWL using RFXCOM component

nenonano · October 31, 2018, 6:38pm

thank you for your answer

would you mind to share your mqtt config? kinda a newbie here
Thank you
