i was not able to reproduce this at my end. the actuator works fine. If you will any issue try restarting th app, wait for the device on the device list to be highlighted, then open and use it.
it seems you have multiple triggers for the same case. Also, you are sending data too much, creating trigger flood. Have a look at this code and change your code accordingly so that data is sent only once when the trigger limit is crossed.
i guess you have hit SMS limit for your device.
if you are changing the code, then I would suggest you create a new device and add new trigger (delete all the old ones)
