Actually, it's not 100% MySensors-related, but I have a working setup consisting of iBeacon (either HM10-based or PI-based) and Beecon app.
When Beecon senses the iBeacon it can trigger various actions, eg make http requests or call IFTTT recipes
Aah ok that makes sense. My application is for rural use and I need the max distance possible. The slow response will not be a problem as the sensors don't send a lot of data at all. So maybe I will stay with the SF4096 for now but I will do some experimenting with the settings. Just to understand them a bit better.
@jocke4u I run 2 RF gateways and it's not a problem. When you 'migrate' a node to a new gateway make sure to run the mysensors clear eeprom sketch first to get rid of the old routing table or you might have issues.
