I/O URL Actions for Shelly 2.5

Dear Forum.

I have a Shelly 2.5 that should be triggered by Shelly motion.

With other Shelly's we have used I/O URL Action like so:

http://192.168.xxx.xxx/relay/0?turn=on&timer=300

When I use this syntaxis for Shelly 2.5 and load it in the browser, I get a "not found" message.

Would somebody be able to give me a hint how to switch Shelly 2.5 with I/O URL Actions?

Hello Wolfgang,

Both relay channels are in relay mode.
I have set the load type for channel 0 to "lights".

Channel 1 is set to "socket".

In the shelly.cloud page in the browser, the Shelly 2.5 has status offline.

However, in the Android app the Shelly 2.5 is present and functioning.

Only function that is not working are the scenes.

Any suggestions would be very welcome.

Eulhofer that is a brilliant answer! Problem solved. Thanks a lot.
