The Hue has its own page where you can see which apps you have linked to your Hue. These can be found at https://www.meethue.com/en-us/user/apps. Is “olisto on olisto” in the list? If so, would you like to deactivate it with the “De-activate” button next to it? Then you can try to reconnect the channel in our app. If Olisto is not in the list, then the conncetion with Hue did not work well and you can try again in our app.
