To interact with the old security system, you typically use bulky keypads with the back-lit LCD screen.
You can learn more about this in my blog post DIY Home Security System with Konnected.io & SmartThings. This results in improved visibility, control and customization abilities of your home monitoring solution. The new setup takes all these existing sensors and exposes them as things in SmartThings where you can use the SmartThings The old system was your typical box with multiple wired sensors hooked up to doors, windows, motion detectors & smoke/carbon monoxide detectors. I recently replaced my traditional home security system with a more modern setup. While I’m leaving this post up, I don’t have much experience troubleshooting this setup, so while I’d like to help, you’re probably best to ask someone else questions about this setup. Since I originally published this article, I’ve switched from using SmartThings to using HomeAssistant & stopped using ActionTiles.
