I am enjoying my first season of these LoRa devices. Full honeymoon phase still...  My biggest problem is I have a sling bag filled with batteries and various esp32 boards and 3d printed cases and nobody is matching my current enthusiasm locally.  Long way of saying, great question..I am not currently able to give a good answer.

Do you have a sense for why self-sovereign wireless communication hasn't really taken off? It's so obviously appealing and romantic.
