As written in a previous log our plan was to control the clock via an android app using the BLE interface of an ESP32 microcontroller. However, we came to the conclusion that it would be more convenient to use the WiFi interface of the ESP. For one, a low energy protocol like BLE is not really needed since the clock is permanently connected to a power supply. Also WiFi functionality allows to update the time from an NTP server and therefore we can get rid off the RTC module. The clock functions will be controlled via a webserver that can be accessed from every device within the same network so there are no Android/iOS compatibility issues.

I already started programming the code which is based on andrei.erdei's VERBIS. Below you can see some preliminary screenshots of the web interface.
