Mqtt from different network

[calasci]

I have a camper network BMS, and home assistant on the home network, how do I use mqtt? Thank you

You could make your MQTT server available via the internet. So it can be accessed from anywhere. You could also use the wireguard ESPHome component to setup a VPN connection to your second network.

Io ho già moduli con mqtt funzionanti , solo jkbms- esphome ha problemi grazie
