Is there some non-prorietary #microcontroller-friendly protocol for communicating on 915 MHz US/868/MHz Europe with available hobbyist-friendly boards? Or even just hobbyist-friendly 802.11AH SOCs that aren't super expensive?
Right now it seems like one's best bet is to just go with HopeRF's #RF69HCW. It's still proprietary and has less range than LoRa, but chips and boards are a lot cheaper and far more widely available. That should be plenty for building a sensor net around one's house without needing a full WiFi and IP stack on each board or dealing with WiFi's poor penetration of walls.
