I have just finished the V2 update, my app does not respond and keeps reporting “Homey is Offline”. I have used Homey successful since the kickstarter project. I have meticulously tried to revert to a previous version, even using the alt-button method doing a factory reset. I am able to set my homey up completely and it confirms wifi connection however still no joy on the app. I am at a loss what to do next, any suggestions?
