Review on WIFI Timer with Configurable Time On/Off Delay, Cycling, 📶 and Optional Trigger - 10 AMP 6V 12V 18V 24V by Mike Zeigler

The user manual link provided worked fine. Instructions where easy to follow. I literally programmed this timer in 3 minutes and installed it in the car in 15 minutes. The car project consisted of installing an Android Auto module and Carplay (phone mirroring) with a rear camera. The module required a trigger to turn it on. The manufacturer suggested installing a normally open snap-action switch. I didn't want to add a switch. First, it should be visible in the car. Second, it must be manually pressed to start the module. I wanted this to work like an OEM install. This timer starts the module automatically without driver intervention. Oh yeah, it's small and easy to hide under the dash.
