We have introduced a new module - "Timers" in firmware v5.21. Now user can use the internal software real-time clock to isntruct NetControl to start a macro at specified time (hour:minute) specifying day of week and month valid for the event! Up to 16 such events can be defined by user.
"Timers" module relies on the NTP(SNTP) network protocol to synchronize its internal clock (there is no battery backed-up RTC module inside NetControl). So you must supply a public NTP server access (via Internet) or configure a local one.
