Hi uvedhe, Let me start with your Ventus W830 station. You can read its data with the weewx intercepter driver. Go to the weewx-user forum and search for Ventus W830. There are three forum items referring to this station. When you have problems with installing or configuring the intercepter driver, start a thread in the weewx-user forum with your question. It will help when you set debug=1 in weex.conf and include in your message the syslog from the start of weewx until a problem occurs.
Then the Davis weather station of your neighbour. BTW. You can put your RTL-SDR antenna on a round metal surface to get a better reception. You don't have to know the serial number of the Vantage station, but you need to know which channel the ISS is set to. It can be set from 0 to 7 and usually the owner will leave the default channel 0. That is also the default of the rtldavis GO program. You could try a few other channels with: $GOPATH/bin/rtldavis -tr 1 (channel 0) $GOPATH/bin/rtldavis -tr 2 (channel 1) $GOPATH/bin/rtldavis -tr 4 (channel 2) $GOPATH/bin/rtldavis -tr 8 (channel 3) .. $GOPATH/bin/rtldavis -tr 128 (channel 7) When your neighbour has a separate station for its wind meter, then the rtldavis program has to be setup for two channels. Just add the numbers of the channels you want. Generally one will set ISS to channel 0 and the anemometer to channel 1, so the command will be: $GOPATH/bin/rtldavis -tr 3 (channels 0 and 1) The way the programs rtldavis (GO) and weewx with the rtldavis driver cooperate are as follows: The rtldavis GO program reads the radio data of the RTL-SDR device, does the frequency hopping and outputs the raw binary weather data on stdout. Besides the 8-byte raw message data the rtldavis program outputs some additional data which weewx uses to calculate the percentage of 'good' and 'missed' signals. Typically a message is received each 2.625 - 3.0 seconds (depending on the used channel). So, as long as the rtldavis GO program doesn't receive messages on a regular interval, it has no use to start the weewx program. It cannot make 'something' from 'nothing'. The weewx program with the weewx-rtldavis driver installed does the following: a. It calls the rtldavis GO program with the parameters which can be set in the Rtldavis section of weewx.conf. IMPORTANT: don't start the rtldavis GO program yourself when using weewx-rtldavis! b. The weewx driver parses the data output of the rtldavis GO program. The raw data messages are decoded and send as 'loop' data to weewx which will do the further handling of the data. See the weewx documentation. The received frequency-error data can be used to analyse the reception. I have configured a weewx plot to show the errors over time. When the frequency-errors are big (i.e. < -15.000 Hz or > + 15.00 Hz) is is likely you will miss signals. This can be fixed by setting a positive or negative ppm correction. The 'good-message-counters' of the first 4 channels are analysed by the weewx driver and each archive interval a summary is printed in the syslog file. Example: May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: last time: last_cnt[0-3]: 1557308415 11495 11254 11041 0 May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: curr time: curr_cnt[0-3]: 1557308715 11605 11364 11147 0 May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: total_max_count=342 total_count=326 total_missed=16 pctGood= 95.32 May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: station 1: max_count= 117 count= 110 missed= 7 pct_good= 94.02 May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: station 2: max_count= 114 count= 110 missed= 4 pct_good= 96.49 May 8 06:45:15 pi35 rtld[452]: rtldavis: ARCHIVE_STATS: station 3: max_count= 111 count= 106 missed= 5 pct_good= 95.50 Hope this helps.
