What this is, is a small inexpensive box that plugs into the wall with a panel of multi-colored LEDs. It can be set on, off, or to come on for various periods after dark. When it’s on it uses the panel of LEDs to effectively simulate the light coming from a television set… and does a good, convincing job of it. From outside of the room the indirect light coming from the room looks very much as if there were a TV on, with the typical changing and flickering patterns that one would see from pans, jump cuts, commercial breaks, etc., with no repeating pattern that I’ve been able to detect, giving every appearance that the room must be occupied.
No more relay boards! The IoT Relay from Digital Loggers
IMHO this product deserves to be better known. I’d hate to have it disappear, it’s a great boon for electronic hobbyists in general, in safety and convenience.
