I read in the operating instructions that you can connect an app via Bluetooth. But it only says "Bluetooth preparation", so I assume that I have to buy an accessory. But I can't find anything. When I try to activate Bluetooth in this way, a red error message appears without any details... I had the original Saeco Royal, which worked for me for an incredible 26 years. Let's see how long this one lasts, the coffee is excellent!
