No fancy code or anything needed on either end.
@rest of people: This message is not going to make sense if you don't understand Home Assistant. My impression of the goal is to support "mqtt discovery". Basically a device posts a json dictionary to a config topic, and HA operates on that data and adds sensors. https://www.home-assistant.io/docs/mqtt/discovery/ and see "Sensors with multiple values". So the mqtt extension, which perhaps has knowledge of all the items in the aggregate, would post to N config topics, one for each item and then all the sensors would just appear. I post an aggregate message every archive interval, and I have 12 sensors configured from the large json dictionary that is published. I ignore a bunch. Obviously, if added, this facility should be optional in the weewx mqtt extension. Some people, me included, don't want my sensor list spammed with stuff they don't care about. I don't mind actual weather data, but extraTemp4 when I don't have a sensor I defintely don't want. So probably the extension needs to have some explicit config. This ends up being a win if the programmatic config saves people time on average. A comment I sent privately was that I want humiidty units to be "H%" rather than "%", because when I look at graphs (in HA still) I want to see humidities graphed together, and battery levels graphed together, not all on one graph. (I even use V for line voltages, aV for 1.5V-nominal, bbV for 2 x 12V lead acid nominal, etc. Yes, I know I'm unusual.) All that said, I can completey see your point that you prefer to just add a few sensors manually with template sensors. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
