I like Home Assistant, it uses MQTT and has an APRS integration.
If an APRS message includes a Message ID as part of a message with acknowledgement request, the Message ID character "{" and subsequent message number are appended to the topic, making it impossible for a radio sending the message to subscribe/unsubscribe/publish to a topic. Some radios send a Message ID by default, with no option to disable.
For example, a radio attempting to subscribe to topic "antenna" might send the following packet:
N2GH>X::BROKER-15:sub:antenna{5
This would subscribe the radio to "antenna{5" - not "antenna"
A small change to the code in aprsmsg.c to ignore the Message ID "{" character and subsequent characters in the string solves this issue, e.g.:
char * token = strtok(stuff, "{");
printf ("%s\n", token);
amsg_process (h, token);
