Mine definitely supports Ethernet and WiFi with password, both what it connects to and the SSID it broadcast, though I had to change some settings on my AP (running OpenWRT) to get it to work.
I logged into the SSID and tried to set a password on the interface itself but then apparently it lost connection to their system and needed to be reset. Not sure as to why an electrician can’t just install an Ethernet cable at the same time as the massive battery
