Shelly Plus 1 HTTP Command Configuration Issue

Hello everyone, I’m facing a bit of a challenge with my Shelly Plus 1 device. I used to have a Shelly 1 that I configured to control my motion sensor with a timer, and it worked perfectly. However, after replacing the Shelly 1 with a Shelly Plus 1, I’m struggling to get the same functionality working. The HTTP command I used previously, <http://user:pw@IP-Adresse/relay/0?turn=on&timer=60>, doesn’t seem to work anymore. I’ve noticed that the Shelly Plus 1 doesn’t have a user field anymore, only a password field. Does anyone know how I can adjust the HTTP command to work with the new Shelly Plus 1 setup? Additionally, I’m having trouble accessing the device’s configuration through the app. It keeps asking for a password, but the user field is stuck on ‘admin’ and I can’t change it. Has anyone else encountered this issue and found a solution? Any help would be greatly appreciated!
