WhatsApp Daily Scheduler Bot

I need a small, focused automation that sends pre-written WhatsApp messages on a daily schedule—nothing more, nothing less. The solution can be built around the official WhatsApp Business Cloud API, an on-device automation library, or any proven technique that keeps the number secure and free from bans.

Key points
• One purpose: automatically push a scheduled message every day to a list of contacts or groups I define.
• Simple configuration: a text file, spreadsheet, or lightweight web panel where I can edit the message body, add or remove recipients, and set the send time.
• Reliability: if the device, VPS, or container restarts, the job must reschedule itself without manual intervention and keep basic logs of each attempt.
• Hands-off deployment: installation script or step-by-step guide so I can replicate the setup on another machine later.

Acceptance criteria
– Message is delivered at the specified hour for seven consecutive days without manual triggers.
– Log file (or dashboard) clearly records timestamp, recipient, and delivery status.
– Source code is provided, documented, and runnable on Windows, Linux, or Docker (any of these is fine).

Once everything works, I will test it for a week, confirm the logs, and release the milestone.
