Playing Shia Azan automatically at home

A phone app is the quickest to try and the least reliable when the phone is silenced or out of the room. A smart speaker can work well if a suitable automation is available in your region. A dedicated device is the most predictable because playing the Azan is all it does.

Automatic playback needs a correct timetable, a device that stays powered and awake, and an operating system that permits scheduled audio. Browsers in particular do not allow reliable background audio.

Decide what should happen during an outage. A device that calculates times locally keeps working offline; one that fetches a daily schedule may not.

Prefer setups that let you enter a city manually instead of sharing continuous location, and check what a companion app collects before installing it.
