This weewx extension allows you to forward your weather data to an AGWPE server for transmission over APRS. For more information, see the Wikipedia article.

• aprs - weewx extension which generates the data field of an APRS packet from archive reports. This can be downloaded here and installed using the weectl extension subcommand.
• pyham_pe - AGWPE packet engine client Python package. This can be installed using pip.

The following configuration items are located in the section in weewx.conf labeled [AGWPEWX].

• host - the AGWPE host to use. Default: "localhost"
• port - the IP port to use. Default: 8000
• callsign - the callsign to use. This will be both the source address of the generated packet and the AGWPE login. Default: "NOCALL"
• via - the path to insert into the packet. Default: "WIDE2-1"
• dest - the destination of the packet. Default: "APRS" (see below for more information)
• interval - the number of archive reports to skip before generating a packet. Default: 2

See also the configuration for the aprs extension which will allow you to set your station's symbol and comment fields as well as whether or not to generate position or positionless weather packets.

weepe uses the weewx's archive generation rate as the "clock" to drive the generation of packets. By default, weewx uses a 5 minute interval for generating archive records. Therefore, the interval configuration item controls how often weepe will generate packets. If you are sending your packets to a AGWPE server which transmits the packets over the air, take care in choosing the value of interval so as not to generate too much traffic, especially if a wide area digipeater is in range.

For example, to generate a weather packet every 15 minutes and assuming weewx is set to generate archive records every 5 minutes, set interval to 2. That is, skip two archive events (10 minutes total) and then generate the packet (15th minute). Note that setting it to zero will cause weewx to generate a packet on every archive event.

The dest item is typically set to one of the character sequence codes as defined here. These usually describe the hardware and / or software you are using. For example, I currently use Direwolf version 1.7 for my IGATE software, so my dest is set to "APDW17". It is highly recommended to change the dest field from the default.

callsign MUST be set to a valid amateur radio callsign. Do not use the default.

via cannot be empty. If you're unsure about what to set this to, stick with the default. There are many references on APRS paths online.
