> Awesome does works but CGG1 with ATC are quite long to detect, I needed to install them 3/4 times before seeing it as we can’t set polling\_interval and scan\_duration into this app (we can with ruuvi app) so default are 60s and 10s scan I have better results with 90s 30s, because 10s we miss often frame let polling\_interval = this.homey.settings.get('polling\_interval'); let scan\_duration = this.homey.settings.get('scan\_duration'); //default value for polling and scan …

but can’t anymore since now `homey install` fire me an error
