TR-069 is now open to every ISP and proven on real Huawei HG8546M terminals: read a terminal's state, change its WiFi and reboot it from Devices → TR-069.
Set it up from the device's page. Enrol a terminal, then open its Connection tab. It shows the login to type into the terminal and each setup step, including where the settings are on Huawei ONTs.
Use the http:// address. Type the ACS URL exactly as shown, starting with http://. Older terminal firmware cannot complete a modern HTTPS connection, so an https:// address never reaches us.
Commands land within five minutes. The first time a terminal checks in, we set it to check in every 5 minutes instead of the 12 hours many ship with. Reads, WiFi changes and reboots now apply within minutes.
The device page updates by itself. Status, last check-in, WiFi, connected devices and each command's progress refresh while you watch, and the page reopens on the tab you were using.
