BN-LINK 7 Day 🌅⏰ “Set It Once” Timer
Honestly… remembering to flip outdoor lights on and off at the right time is one of those “I’ll do it later” tasks that never quite makes it to the top of the list. This BN-LINK astronomical timer switch is built for people who want their lights to behave automatically—without constantly thinking about sunset times.
This is a 7-day programmable in-wall timer switch that uses automatic sunrise & sunset control after you set it up. It offers 18 on/off programs (with 7-day options) so you can match different routines—think porch lights, entryway lighting, garage lights, hallway lights, and more. It also includes a Random mode that can help create the illusion of occupancy when you’re away.
Setup is where the real magic happens: you’ll choose the correct time zone during setup for accurate calculations. For day-to-day control, it lets you switch between AUTO (scheduled operation) and MANUAL (direct on/off) with a simple press-and-hold on the front cover. There’s also a built-in backup battery to help retain settings during power outages.
