I have a pretty long driveway and would love to have alexa or google home announce when I receive mail or when a car comes up the driveway. I have been using ESP8266 for this project but realized that the distance and power consumption makes it near impossible to make it work. I really need a lower frequency carrier to make the distance possible. I also need low power and Helium with Arduino support sounds perfect.
