It uses ESP-NOW (close to WiFi in some sense but reduced in number of 
OSI layers, and LoRa. In the first case there is not IP but MAC, the 
second is a proprietary protocol.

That's true. This is what it is designed for...

The data is encoded and encrypted. Not so safe as using AES or some 
standard protocol, but safe enough for a control of local premises. 
Using LoRa means that you have to find a proper ratio among length of 
messages and safety.

We work just for that: first level devices work in an isolated group 
doing their job. Nothing else required. Second level adds a HUB, that 
manages the group from a single point, still local. But the HUB have the 
added task of publishing to an MQTT server in, possibly a Home Assistant 
LOCAL server. Finally is up to the user to open HASS to the world trough SSL
