In my first post I had a mistaken assumption. The information to follow is correct...Tech specs show my Hitron Gateway to use 2.4 GHz wi-fi. On my phone I enable location access for the Roborock app, but the app cannot find the vacuum. I can't see why my two Samsung phones cannot find and communicate with the vacuum.
Hi, E2 could only work with Mihome app. Please check attached file.
