Thanks, guys! I was toying with the idea of setting up a second Pi/SDR and just grabbing the data "off the air"; but, I think MQTT is probably a better choice.

But it is generally reliable, and pretty much everything these days supports it. Regardless of how you choose to store and process data, it's a reasonable choice for getting data from generators to processing systems. In my case, I have a weewx setup and also Home Assistant. I am running mosquitto as the broker. Weewx is running normally with a Davis station. It also has the mqtt extension and I publish archive records (every 5 minutes) to MQTT. In my case I am not using MQTTSubscribe, but if I had more sensors that I wanted weewx to process I would do it that way. I have a few sensors that post to mqtt, mainly built with ESP8266/NodeMCU. These are for indoor temp/humidity, and voltage on an small off-grid solar/battery system, and a few other monitoring type things. I should set up the rtl_433 bridge as well, to pick up an Acurite 6045M lightning detector. Perhaps I'd put lightning into weewx. (I'm still experimenting with rtl_433 and don't yet have it "in production".) In Home Assistant, I of course have mqtt configured, to read the indoor sensors. I'm not interested in years of trends -- this is mostly about notifying me if things go out of bounds, and me knowing if the heat has been running. So I have not tried to put this data into e.g extraTemp1 in weewx, but I could. In addition I ingest basic weather data from what weewx posts, for display and to enable automations. I don't follow your notion that sending data multiple places as "brute force", but if you mean hardcoding a switching plan into rtl_433 just for you being icky, I see your point. Using mqtt, and having various of your systems subscribe as needed is a good solution. If you are doing weewx and HA, I think you'll find that you want to add one of them to HA that you didn't originally, and it's easy to just add an mqtt sensor to the config. -- You received this message because you are subscribed to the Google Groups "weewx-development" group.
