These are the instructions that Kamoer sent me
Good morning, pls try the below instruction
1. Turn on mobile data in mobile network settings
2. Find the personal hotspot settings in the phone settings, set the hotspot SSID
to ali_mprov_ZL, and set the password to 111111111
3. Turn on personal hotspot.
4. Power on the dosing pump, operate the reset button to put the dosing pump into
the network distribution state, and then wait for the dosing pump to connect
automatically.
The blue light will stay on after success.
5. Find another mobile phone to connect to the personal hotspot, log in to the App,
and find it in the Local Devices list on the Add Device page.
To see the device, select Bind.
I change the routers name to ali_mprov_ZL, and Pw 111111111
One minute later I manage to pair the put with the app
