This is an inexpensive, minimalist shield for LoRa RA-01 modules, https://www.aliexpress.com/item-img/LoRa-Series-Ra-01-Spread-Spectrum-Wireless-Module-Ultra-10KM-433M-RF-Chip-SX1278/32799821469.html#
I don't know whether MySensors yet supports LoRa, but I'm sure someday it will. Meanwhile, until then, you can use the RadioHead library to interface with it. The RadioHead library contains demo code examples that you can run. http://www.airspayce.com/mikem/arduino/RadioHead/ The RA-01 modules use the same Semtech chip as the HopeRF RFM95/96/97/98. Therefore, you can use the same code as the RFM95 to interact with it.
Up until just recently, LoRa has been relatively expensive. The RA-01 is a price breakthrough, just as the ESP8266 was. LoRa is probably most renowned for enabling relatively long distance wireless communications at relatively low transmit power. In a home environment that translates into highly reliable communications with generally full coverage and no repeaters needed.
