INNR RC 210 cover - 503 flush-mounting box

To use in combination with something like this.

Why install an INNR smart button and not any other brand?

INNR button provides Zigbee binding, so it works even when the coordinator is down, not to mention that there is no latency in turning on.

How do I manually “bind” my INNR smart button to my INNR bulb?

You can bind the smart button to any bulb directly, without the aid of a Zigbee bridge/cordinator; just press the smart button three times quickly and hold the third press for three seconds near your INNR bulb.
