{SOLVED} NotifyMyAndroid not working for me

I have registered an account with NotifyMyAndroid and received my API key. The binding is installed and appears to be operating normally, my config works and I can generate a notification. However I can only make a single call per day as I call I get an error stating that I have used my daily allowance from my IP address.

There is only a single rule in place and that’s purely for testing. I have a switch that when changed to ON sends a notification. I manually select the switch state.

Has anyone else experienced this before and found a solution or is NMA no longer maintained and not worth any effort? If so then what are the alternatives?

Turns out to be a configuration problem. I had left the option; appName= blank as per the comments in the config file. Once I added; appName=openHAB it now works as expected.
