Help with refreshing garage controller automatically

[RBoy (www.rboyapps.com - Making SmartThings Easy!)]

So refreshing a device in done by the poll() function in ST and the frequency is controlled by the ST platform (no control over it). However if you want to manually poll a device and get it to refresh itself, you can use the poll() function and a great app to do that for you is Pollster

[OBSOLETE] "Pollster" - A SmartThings Polling Daemon

Please note that excessive polling of some devices (particularly Zigbee and Z-Wave) may cause network congestion and lead to degraded system performance. Therefore, polling rate faster than 5 minutes is not recommended. The author of this software bears no responsibility for your system performance. Use it at your own risk. I don’t claim originality of the idea, but I needed one badly for some of my projects and didn’t find anything among the shared apps. So there it is… Many SmartThings devices rely on polling to periodically update their status. These devices have ‘polling’ capability and provide poll() function that the SmartThings polling engine calls approximately once every 10 minutes. Unfortunately, SmartThings polling engine proved to be unreliable and sometimes it stops working…

EDIT: Polling every 20 seconds is an overkill, you shouldn’t have to poll it ideally since it’s an event driven architecture so the device will update itself everytime there is a change in the garage door status. If that isn’t happening the question to ask is why (and 99% of the time it’s a communication issue between the device and hub and lots of little ways to solve it from reboot hub, repairing z-wave network and for the GD00Z-4 aligning the antenna, see this thread). The antenna on this device is very sensitive to direction.
