Hey guys, I thought of a new project.
I have a EM83 Tube at home and I want to build a charging station for my iPhone and Apple Watch with it.
I planned this so that the tube will sit in the middle of the station and on the left and right of the tube the wireless chargers for my device. Then I want to display the current battery percentage of both devices on each of the displays of the tube.
The controlling of the tube is no problem for me, but where I am stuck is the transmitting of the battery level to the ESP. I thought about UDP Packets which I will receive on the ESP but I don't know what i should use on the iPhone to transmit the battery level. Maybe you guys have an idea if there is already an app out there that can be used for something like this or if i need to code it myself.
I want to send an update to the ESP if the batterylevel changes or every minute, but not longer than that becuase i want it quite "realtime".
If it makes it easier, my iPhone is jailbroken and has iOS 13.3
Thank you all 
EDIT: I want to update/send the packets only when the phone is on the chargingpad and charging.
