executing commands on VeraLite by entering URLs into Web browser

I thought when I enter a URL like the following into a Web browser it should execute on Vera:

http:192.168.1.137:3480/data_request?id=action&output_format=json&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1&DeviceNum=60

Mine does not. I can access the UI at the IP address, so I know that is correct …

Can you try: http://192.168.1.137:3480/data_request?id=action&output_format=json&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=1&DeviceNum=60

got this error:ERROR: Invalid service/action/device

But when I ran the following scene URL it did work:

http://192.168.1.137:3480/data_request?id=action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunScene&SceneNum=5

How would I have to modify the device command to make it execute as well?

I apologize: I entered the altid instead of the device ID :-[
