Quick Answer:

Installing Esysense motion sensor products: plug-and-play products (sensor bulbs, hinge lights, rechargeable lights) require no tools or electrician — replace the existing bulb and leave the wall switch permanently ON. Hardwired products (panel lights, tubelights, downlights, standalone sensors, staircase controllers) require standard mains electrical connection — a licensed electrician is recommended. For all products: never connect to a dimmer switch; always leave the wall switch permanently ON. This guide covers step-by-step installation for every product category and a 14-problem troubleshooting table.

Pre-Installation Checklist — All Products

• Power off: isolate the relevant circuit at the MCB before touching any wires. Verify with a non-contact voltage tester.

• Fitting compatibility: E27 (screw) or B22 (bayonet) for bulbs | surface ceiling with wiring for panels | existing T8 holder for tubes | false ceiling with 90-120mm depth for downlights.

• Switch type: motion sensor products require a standard ON/OFF switch left permanently ON. NOT compatible with dimmer switches, timer switches, or two-way switching.

• Wiring identification: Live (brown or red in India), Neutral (blue or black), Earth (green/yellow). Use a circuit tester if unsure.

• Product manual: every Esysense product includes a printed installation guide. Read model-specific wiring diagrams before proceeding.

Bottom line:

The most common installation mistake across all motion sensor products: leaving the wall switch in the OFF position (which kills power to the sensor) or connecting to a dimmer switch (which causes flickering or failure). The wall switch must be ON permanently.

Installing Motion Sensor Bulbs — 8 Steps (No Tools, 5 Minutes)

1. Switch the wall switch OFF.

2. Remove the old bulb — anticlockwise (E27) or push-and-rotate anticlockwise (B22).

3. Inspect the socket — clean if necessary, confirm center contact is not recessed or corroded.

4. Insert the Esysense sensor bulb — clockwise until snug (E27), or align pins, push, and rotate clockwise until it clicks (B22).

5. Switch wall switch ON — leave permanently ON from this point.

6. Allow 10-30 second startup calibration — brief flash or dim glow is normal during calibration.

7. Test: walk away from detection zone, wait 10 seconds, walk back in — bulb should illuminate within 0.5-1 second.

8. Day/Night test (LDR models): cover the sensor window with your hand in a lit room — bulb should illuminate. Remove hand — bulb should switch off after delay.

Frequently Asked Questions

Q: Do I need a licensed electrician to install Esysense products?

A: For plug-and-play products (sensor bulbs, hinge lights, foot lights, rechargeable lights) — no electrician needed, same as changing a standard bulb. For all hardwired products (panel lights, tubelights, downlights, standalone sensors, staircase controllers) — a licensed electrician is recommended for safe, standards-compliant installation per Indian Electricity Rules.

Q: Can I use two motion sensor bulbs in the same room?

A: Yes — each bulb operates independently. Radar sensor bulbs may have minor interactions but these rarely cause practical problems. For large rooms needing full coverage, two bulbs at either end of the room is the correct approach.

People Also Ask

Q: How do I install a motion sensor bulb?

A: Turn off the wall switch, remove the old bulb, screw in the Esysense sensor bulb, then turn the wall switch back ON and leave it permanently ON. The motion sensor handles all switching from that point. No tools, no electrician, 5 minutes. Do not connect to a dimmer switch.

Q: Why does my motion sensor light keep switching off while I'm in the room?

A: Most common causes: delay is too short (increase via TIME potentiometer), sensitivity is too low (increase via SENS potentiometer), or a PIR sensor is losing sensitivity in high Indian ambient temperature. For summer-reliable performance, switch to an Esysense radar sensor model.

Conclusion

Correct installation is the foundation of reliable long-term performance from any Esysense smart lighting product. For plug-and-play products: 5 minutes, no tools. For hardwired products: standard mains connection with a licensed electrician. For all products: wall switch permanently ON, no dimmer switches.
