Oh yeah, it&#x27;d make Rube Goldberg proud. At the time it was actually my very first piece of home automation. It was built before the zero, Edison, or other dual system devices came around, and I got frustrated with timing issues trying to set up a two wire serial between the 1st gen Pi and the Arduino- so I looked about my shelves for something else and decided on using the 2.4Ghz NRF modules I had [0]. The Pi went from being VPNed into my VPS so that I could have an app on my phone to integrated to Alexa, and a bunch of steps in between over the last half decade.<p>I went from Arduino from the store to building my own using a flashed chip so I could drastically reduce power and make it coin cell operated, just to see if I could. Stuff like that.<p>I&#x27;ve actually just ordered an off the shelf Z-Wave garage door interface. My bundle of wires sitting on the garage door opener in a 3D printed case has always just been an excuse to play with something new when I didn&#x27;t want to really spend all that much time figuring out what my next gadget should be.<p>Thanks for the link though! I&#x27;ve been wondering what kind of Z-Wave interfaces are out there that I could use in micro controller projects. Most of my experience has just been 2.4Ghz and Zigbee.<p>[0] <a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;dp&#x2F;B00E594ZX0" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;dp&#x2F;B00E594ZX0</a> (mine originally wasn&#x27;t the + model)
