Support for WH65B station

[tguozden]

Current Situation

Hello, thanks very much for this repository. We are working in a students project to acquire data from several weather stations and this is could be really useful.

We started with a fine offset WH65b, which we can see with a rtl-sdr device and rtl_433 for linux.

Using the example posted here with OOK_modulation=false (FSK) there is no information parsed through to the monitor. Although we can see output with each transmitted message when turning on -DRTL_DEBUG=1

Using openmqttgateway and home assistant didn't work either.

Is the device supported? I see in the code that seems to share modulation with WH24

We use a Heltec 915 Lora device.

I also add that the reception strength is poor, we miss the signal after in distance greater than 5 meters.

Here is the monitor's parsed output for each station's transmision: (RTL_debug=1)

No response

Hello, also tried to listen to a temperature-humidity sensos Fine Offset WH2 (OOK modulation?) but couldn't either. I tried OOK and FSK mode and almost every other posible setting combination but there was no response.

I could only get some information parsed with each message when using same settings as with WH65: FSK modulation and debug > 0.

Also check again using openmqtt and home assistant, again nothing happened. (wifi and mqtt connected)

Please any advice would be very welcome.

Take a read of this issue, they recommended a change to MINIMUM_SIGNAL_LENGTH that resolved a reception issue.

[tguozden]

Thanks! Got it working with MINIMUM_SIGNAL_LENGTH=500 as the previous post said.

Although (also as in the referenced post) with poor signal reception: rssi lower than -80 with the heltec and the antenna alongside the station.

Still I cannot decode the WH2 sensor. Any ideas? The sensor is OOK. If it is useful, the only way I could obtain some parsed information was in FSK mode, debug = 1 and the older value of MINIMUM_SIGNAL_LENGTH

Thanks again
