The big problem with LoRa today is that in some places, the typical frequencies you can use for LoRa (915MHz in the US) are saturated with traffic. Also LoRa literally is Long Range, and those IoT packets might be heading out >1 mile from your house easily.

It will work when n==1, but not when n==1000 in a square mile, say. Given that, I would certainly be trimming back on the power so it doesn't transmit more than 500 feet out of your house. I've had a heltec Meshtastic receiver broadcast about 2 miles line of sight easily.

And then there's the whole thing about encryption, since your packets can travel miles, and your devices can receive packets from miles away...
