So anyone who integrates their inverter into a public WiFi has only themselves to blame and, to be honest, can't be helped.
private and secured WiFi but public Mqtt broker is ok. Alternative is a wired LAN if WiFi is not possible.
Even in a home network, it is useful to manage access because children can simply accidentally get into the settings and change them. It happens that guests or neighbors are given access to home Wi-Fi, in our country this is normal.
Even a simple PIN code is enough.
And there are also viruses that can infect devices that get access to the Wi-Fi network.
you can also create a "v-lan" with separate wifi key, so that no one can connect to this ssid. Don´t forget to get access only to the 2,4 Ghz (some ESP32 have problems with 5 Ghz Network)
Please add simple web authorization. Additionally, you can add IP-based access control. Sometimes inverters are connected to public Wi-Fi networks and third-party access is highly undesirable. Thank you!
