Well! I must say, I'm quite impressed with your progress.
I had wondered how well the WS-2000 sensors would work with rtl_433. I'm using a WH25B from Ambient Weather to get indoor temperature, humidity, and barometric pressure.
https://www.ambientweather.com/amws1000bth.htmlI wasn't aware of the WH32B when I bought my WS-2902A. The WH25 is supported in rtl_433 with some recent tweaks.
https://groups.google.com/forum/#!topic/rtl_433/nsZsA7BoggwI'm glad to see that the WH31B seems to work. Can you tell me what rtl_433 reports it to be?
As far as the WH32B goes, I'm sure that rtl_433 can support it with some work. I was in a similar situation when I tried to see the WH65B signals. rtl_433 didn't report anything either. After some research, I was able to capture the raw signals in the manner described at the bottom of this page.
https://github.com/merbanan/rtl_433Now, you will probably need more switches than -a -t. At least the frequency will need to be specified, -f 915000000. If you're using one of the cheap SDR dongles, you might want to determine the ppm error and specify that, -p <ppm_error>. You will certainly need to somehow make sure that you're only capturing the WH32B signals. I have had quite a bit of trouble getting the visual SDR tools to see the signals put out by these devices. They seem to be quite faint. And they transmit only about once a minute.
Once you are able to capture some raw signals, those captures need to be made available to the rtl_433 developers. The process for this is described in the rtl_433 wiki on github.
https://github.com/merbanan/rtl_433/wiki/Adding-a-new-remote-deviceI had never done this before, but I managed to stumble through the process.
The rtl_433 developers are quite knowledgeable and once they see the samples, they can tell an amazing amount about what they are. In my case, we needed to take a couple of runs at it. At first, they thought it was the same as the WH24 sensor array.
https://github.com/merbanan/rtl_433_tests/pull/234After I had some experience comparing the data from rtl_433 and my WS-2902A console, I realized that there were some differences.
https://github.com/merbanan/rtl_433/issues/844At that point, the WH65B was fully supported. I don't think the WH32B will be nearly as difficult to support as the WH65B was. I expect that the protocol will be very similar to the WH25. But the rtl_433 developers are very able to sort it out. Please feel welcome to PM me or post if you like. I'll certainly do what I can to help.
