Pretty easy installation once you understand the basics of wiring. Fairly simple, unobtrusive-looking panel. You need to follow the instructions carefully to set it up properly. I set mine up with daylight saving time (with appropriate zone) and random on/off (+/- 30 minutes) for my porch security. Once set up, it ran like clockwork, turning on and off after sunset to turn itself on and turning off at 11pm, all within plus or minus 30 minutes to seem more random. No re-setup or reset required…
