Yes, that could be changed, but it's a bit of a hassle to implement with the bluetooth and and storing state on an embedded device. So I haven't implemented it yet and I can't promise if and when it's coming. If I am not hit by a metaphoric truck, I give my best to make sure not to disappoint my customers. My plan is to keep the backend running for 10 years after I sell the last display. But of course that's just a plan und I understand that you may not like the odds. That's totally reasonable.
