I really need to see the output from the command line. You can run the app from the CLI. It will overwrite the current install. After running you can install it from the app store again. Your settings will be saved.
It could also be that there is something wrong in the pairing template. You can test this by pairing the device through the developer tools on https://developer.athom.com/tools/pair. While pairing keep your browser developer console open and look for errors (press F12 in your browser and select tab console).
