Compatible with IKEA HOME SMART. Connects to your home Wi-Fi, allowing you to remotely control compatible products. Remote control (sold separately) allows you to turn lights on/off. I connected it for about two weeks, but the room is small and I never actually used the remote. Also, I've already purchased other lighting, etc., from sources other than IKEA, and I don't see any future expansion possibilities, so I'm selling it. If you need AAA batteries, I will include them, so please let me know. The total cost was about 10,000 yen. I think this is a good product for those who use many IKEA products and are considering remote control and automation. Please check the image description extracted from the official website for details.
