Yes, OIO products support the Matter protocol, and can be brought into any Matter system without OIO App. However, the circadian schedule (Wake-Up, Evening Transition, and Nightlight) will not be adjustable outside of the OIO App. These events will occur at 6:00am, 7:00pm, and Midnight respectively. Lights will not turn on automatically at these times, but they will change spectrum to be appropriate for a typical circadian rhythm.
