Bluetooth AC Motor Controller Development

I need a compact, reliable controller that can switch an AC motor ON and OFF and let me set timing schedules from a smartphone over Bluetooth. The wireless link is the only command channel I expect to use—no analog or hard-wired digital inputs—so please choose components and firmware that make a stable Bluetooth connection simple for an everyday user.

Key points to cover
• Motor type: single-phase AC, 220 V supply.
• Functions: instant ON/OFF plus programmable countdown and recurring timers. No speed or torque regulation is required.
• Control method: Bluetooth LE connection to an Android / iOS app (a basic demo app or clear API documentation is fine).

Deliverables
1. Schematic and BOM for the controller board, including protective circuitry for the AC load and an onboard Bluetooth module.
2. Firmware source code with commented functions for pairing, command parsing, and relay drive.
3. A simple mobile app or example code that sends the required commands.
4. Assembly, wiring, and safety instructions so I can reproduce the build and pass local electrical inspection.
5. A short test video that shows the motor being started, stopped, and run on a timer from the phone.

I will validate the project by flashing the code, pairing a phone, and observing at least three consecutive timer cycles without communication dropouts or missed activations.
