sgjava Posted February 22, 2020 Posted February 22, 2020 I've installed a wireless alarm system, but I want to use all my old wired stuff from my original alarm system. I started down the road of using an ESP8266, but GPIO.INT was flaky and GPIO pins limited, so I ordered a MCP23017 and figured Why not just do everything with one NanoPi Duo? I have a few of them and they are made for breadboard prototyping. Plus with the built in Ethernet I can have wired primary and wireless backup networking. I even rolled my own Ethernet adapter since the breakout adapters cost $5+. If you have already done this and have any wisdom to share I'd like to hear it. No turning back now!
