Thanks- I'll take a look and report back if I sort anything out. And yes, mwall seems to do some terrific stuff, but a driver isn't what I need. I don't want to replace my wx station with MQTT sensors, but add some soil temperature readings, etc., from other Pis scattered around my house and yard. I'm currently parsing text files as a service, but subscribing to an MQTT topic would be much better I think.
