This follows the MST-91Ai EN Rev 1.0 manual in AP mode. Its initial AP address is 192.168.7.1; a changed AP address or Station-mode address takes precedence.
While connected to the weather station's authorized AP Wi-Fi, enter 192.168.7.1 in your browser's address bar only if it remains the current AP address.
Use the current web-access password; 12345678 is initial. The web TCP port defaults to 80 and can change. Wi-Fi and web-access passwords are separate. The reviewed instructions do not establish a numeric management scheme.
Confirm the existing mode
Check the mode, current Wi-Fi, address and web port with the installer. In Station mode use its assigned or configured address; do not assume the AP address applies.
Read Status
Open Status to inspect model, MAC address, uptime and free memory. Station-only signal and internet fields do not apply in AP mode. Leave Home heating/relay controls and settings untouched.
If access fails
Confirm the current web password with the installer. Do not switch modes, restart, reset or change heating settings to perform this check.
