heltec-rtl_433-fsk setup for Bresser 7 in 1 weatherstation #128

Open 2nice4u opened 9 months ago

2nice4u commented 9 months ago

Current Situation

With the original rtl_433 version and an SDR stick I can retrieve the BRESSER 7-in-1 weather station with the following command: rtl_433 -f 868.2M -s 1000k -X 'n=Bresser-7in1,m=FSK_PCM,s=125,l=125,r= 9000,preamble=2dd4' But how can I do this in OpenMQTTGateway v1.7.0? How can I control rtl_433 there or is there a config file?

Configuration

I need a way to execute this command in OpenMQTTGateway.

Rtl_433_esp is controlled thru compiler directives and they are listed in the README.

in your example, you are using a Flex Decoder which is not supported due to resource constraints on the esp32. But you could try setting the frequency and enabling FSK signal demodulation and see what is received.

Unfortunately the protocol: "[173] Bresser Weather Center 7-in-1, Air Quality PM2.5/PM10 7009970, CO2 7009977, HCHO/VOC 7009978 sensors" is not supported by rtl_433_esp.

rtl_433 -f 868.3M -s 1000k -R 173
