Is it possible to add support for Inkbird ITH-20R

[gregb79]

Hi,

is it possible to add support for an Inkbird ITH-20R for esp32 with cc1101 i am not sure how to add additional decoders. a link for it working with rlt_433 is , https://github.com/ehagan/rtl_433

hopefully you can help as i want to log this sensor in home assistant,

thank you in advance.

A couple of comments

1 - My next release will be based on the FSK branch, so any changes will need to be applied their first

2 - The library currently supports only OOK/ASK Modulation do you know what modulation scheme it is using? You can find this in the device decoder file for the device.

3 - If you can submit a pull request against the FSK branch with the device decoder file placed in the contrib directory, I can run the build script that updates the code base for the additional file. My draft update script is here

https://github.com/NorthernMan54/rtl_433_ESP/blob/fsk/tools/update_rtl_433_devices.sh

If your curious as to what changes are required to add support for additional devices you can look at the update script

4 - As I don't have the physical device I will not be able to perform any testing, so will need your sign off on it working correctly.

5 - What framework are you using with this ? ie OpenMQTTGateway or ?

Hi, Thank you

Thank you in advance.

It appears the inkbird ith-20r is FSK_PULSE_PCM i tried to create a pull request in the fsk branch hopefully that worked i am planing on using openmqttgatway to send the data to Home Assistant for logging.

the code in the decoder file is .

HI i tried to attach a copy of the decoder file,

inkbird_ith20r.c.txt

Thank you.

[NorthernMan54]

If you look at the decoder file, it is fsk and not ook/ask. At the present time only ook/ask is fully supported, and I don’t have fsk working. And the road map fsk has a fair bit of effort to go, so may not be launched for a few months.

[gregb79]

HI ,

Thank you for the update, I appreciate all you help.

I look forward to this feature being added, I am more than happy to help test with the inkbird ITH-20r device,

Kind Regards

Greg.

Would appreciate to have this device supported as well!

@riegelbrau FSK is still a future feature.

[riegelbrau]

I read that, but wanted to give some "pressure" 🙈.

[seb821]

Hello,

I have got a Inkbird IBS-P01R that uses the same protocol as the Inkbird ITH-20R.

Now that FSK has been implemented, I thought I would give it a try. I have Lilygo board 433 MHz that works well in OOK.

After changing OOK_MODULATION to false, here is what I was able to catch.

Unfortunately it does not decode properly.

Any idea of parameters I could change or tests I could perform to go forward ?

Please see my command line from inside my Docker Container running rtl_433 native on my Synology NAS:!

I am not sure I understand. What is providing the rtl_tcp server ? An esp32 ?

[riegelbrau]

You asked for parameters. Even I don't know how to modify parameters inside the ESP32, I wanted to show, with which parameters rtl_433 running on Linux decodes the sensor quite well. May be that helps, may be not.

[NorthernMan54]

@riegelbrau @seb821 The current release includes support for FSK, so this should be able to push forward. Unfortunately I do not have access to an Inkbird device, so my ability to troubleshoot this further is very limited.

[seb821]

I was hoping that with raw or unparsed signals something could be done. But I completely understand it is very difficult to troubleshoot remotely. Thanks for the feedback.

[riegelbrau]

Today I've got managed to compile the image for the board "ttgo-lora32-v21" with option -DOOK_MODULATION=false to test my FSK modulated devices. For the Inkbird ITH-20R I did not recognize any mqtt messages, while the sensor did successfully send messages to the native rtl_433 instance. The Lilygo did successfully send configuration messages for two seperate sensor ids of type "Ford TPMS" and messages from my "Jansite Solar TPMS" that I use to control the carbonization of my home brewed beer during the secondary fermentation . I only used the console messages and the mqtt messages. I have no clue how to see other logs of the rtl_433 instance on the Lilygo board. If I get some hint i will provide some log output or debug infos.

Regards Christoph

[riegelbrau]

I tested again with OMG V1.7 fsk-version, which should have the newest release of RTL_433_ESP integrated. The ITH-20R does not appear at all, while I see the messages in my native rtl_433 instance. How can I help with testing?

[NorthernMan54]

One thing people have found, is that in FSK mode the frequency setting needs to be more exact. Can you lookup the exact frequency with your rtl_sdr then try using that frequency ?

[riegelbrau]

I am running rtl_433 with 433.92 MHz. The MQTT messages show two frequencies: One is very near to 433.92 and the other is lower. I tried both with OMG V1.7 without success. Are there any other parameters that should or might be adjusted?

[NorthernMan54]

There are other FSK related settings that are internal to the code base- https://github.com/NorthernMan54/rtl_433_ESP/blob/276bc2cc6cef73037aaf3325b69be99ccd139742/src/rtl_433_ESP.cpp#L267

If you look at the OOK_Receiver example https://github.com/NorthernMan54/rtl_433_ESP/blob/276bc2cc6cef73037aaf3325b69be99ccd139742/example/OOK_Receiver/OOK_Receiver.ino#L75

I had added code to 'twist the knobs' and see if I could get better results during testing. I had tuned the values based on the signal from my FineOffSet WH51. You could try using that against your device to find a better setting.

When I was doing the testing, I let it run for about a day for each knob, logged the serial output to a file, then did some statistical analysis to figure out the best setting for each knob. I let it run for a day, as the sensor only sent a signal every 60 seconds, and wanted to test each setting a few times.

[riegelbrau]

How can I create and run this example on my Lilygo TTGO Lora32 T3 V1.6.1 and produce a log like above? For the test the device needs to be filtered for only the ITH-20R. I saw the my_devices directive, but where must I set the filter?

[NorthernMan54]

The MY_DEVICES directive is in a couple of spots, and you can use it to only include a subset of decoders to use. When I did my testing I did not use a subset but the full list of decoders.

I then did some statistical analysis on this log line. Log.notice(F(CR "Finished %s: %s, count: %d" CR), TEST, stepPrint, count);

[riegelbrau]

I've got managed to compile the OOK_Receiver example only with the compiler settings for setBitrate and -DsetRxBW. With -DsetFrequencyDeviation I get compiler errors:
