Before I added the devices to my Smartthings Hub I used the GitHub code from @mitchp to create a device type. From there its working great. 2 of the Trippers I installed were not showing battery level when first paired but removing them and resetting the device worked once they were paired back to the Smartthings Hub. There is an issue with the battery level only showing in levels of 11 but for me that’s not a big problem at the moment.
There is a discussion regarding this device here
