High sensitivity: down to -148 dBm. From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.

very impressive work. Can´t wait to give it a try. So many things in one project, looks very useful. I think that alone through the intgrations like snips this could become a stand-alone, closed mysensors/mqtt hub, where almost everything is integrated what you need. Can´t wait to hear more of this project.

@doug Can't wait for you to release the BOM

@MiKa Hi. oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping. https://github.com/mattairtech/ArduinoCore-samd
