Custom Sensor Integration Issues

I have a current OpenHAB installation and several custom sensors (temp/humidity and garage door control) that I have been able to integrate using a custom device handler and REST. I am able to get updates when hitting an update button but have not yet been able to set an update schedule using the scheduler. I tried to add the command runEvery5Seconds() to the device handler as shown below as well as trying to write a smartapp with the sole purpose of updating the temps. Any help here would be GREATLY appreciated.
