Setting up a home Azan clock

Put the device where the household already gathers, not in a spare room. Audible from the kitchen and visible from the hallway beats perfectly positioned and ignored.

Set your actual city, not the nearest large one. In a big metropolitan area the difference is a few minutes; across a region it can be much more.

Choose the calculation profile your community or marja follows, then compare a week against a locally reviewed timetable before trusting it.

Set Fajr quieter than the rest. If anyone in the home is a light sleeper, start lower than you think and raise it after a few days.

Agree quiet hours and which prayers are called aloud. A setup that works for everyone stays switched on.

If something is off, check location, timezone, daylight saving and method in that order before adjusting anything else.
