Not directly related to this. I own a CTEK one car battery charger. CTEK is not some Chinese company but a very reputable Swedish company. Their car battery chargers are very reputable. But the CTEK one has an accompanying App. Both are connected via Bluetooth like in this reversed battery monitor. You can add the battery charger to the app only, when you have a CTEK cloud account. Just this weekend, their cloud servers had problems. So you I was unable to connect to the local device in front of me. What I'd like to say: CTEK requires a working cloud account to access their latest device via Bluetooth from within their app.
