IoT-based Machine Utilization Monitoring project for a CNC machine and conventional lathe.

The objective is to detect machine states (OFF, IDLE and RUNNING) and record their operating times using an ESP32. We want a non-invasive current measurement solution. The machine has an incoming AC supply through a stabilizer, which is converted internally to DC for the motor. I need help with: Selecting the correct AC/DC current sensor. Designing the sensor interfacing and signal-conditioning circuit. Preparing the complete hardware BOM and wiring diagram. Testing the setup to distinguish OFF, IDLE and RUNNING states. I already have an ESP32 DevKit and some basic electronics components. Could you help validate and build a working hardware prototype? Please share your experience and estimated charges.
