@gemlog Haha awesome! I think I cracked the SEO because I made so many posts pointing to the same article 😉

@gemlog Yep that's a terrific use case for LoRa! WisGate and PineDio Gateway will work fine as LoRaWAN Gateways.
Also check out these LoRaWAN Sensors: https://www.tindie.com/search/?q=lorawan+sensors
@gemlog Thanks for reading my posts 🙂 Here a good intro to LoRa: https://makezine.com/2021/05/24/go-long-with-lora-radio/
My articles talk about building our own LoRa Sensors with BL602 and Semtech SX1262 Radio Module. (Should work with ESP32 too I think)
For the LoRa Gateway we can get a RAKwireless WisGate developer gateway: https://store.rakwireless.com/products/rak7248?variant=40528974446790
Or we can wait for Pine64's PineDio Gateway: https://lupyuen.github.io/articles/gateway
Do you have any use cases in mind for LoRa?
