What this diagram shows

Controllers keep running locally if the internet drops
Sensors use LoRaWAN; cameras use the wired network
Remote access is only through a VPN

Prompt used

Smart greenhouse network: LoRaWAN sensors (temperature, humidity, soil moisture, EC/pH) connect to a LoRaWAN gateway; a climate controller drives fans, vents and misting; a fertigation controller runs drip irrigation; IP cameras watch crops. Everything sits behind a router with firewall and LTE backup; data goes to a cloud dashboard and remote access is via VPN.
