HomeKit Connected Fence Door Monitoring System

HomeKit Connected Fence Door Monitoring System

Summary The objective of this project is to create a solar powered, HomeKit connected outdoor fence door monitoring device. Once setup, the door’s state (i.e. open/close) can be monitored and used in automations within the HomeKit ecosystem. I’ve been using it for months now, and it has been working really well. See below a video of the system in action. This is not a difficult project, but there are several moving parts associated to it, so I’ll try to be thorough in the following sections....

I decided to give it a try and design and print my own desktop tripod....

Seeed Wio Terminal

Wio Terminal - All In One Microcontroller

The people at Seeed Studio have been busy working on a bunch of new devices. From IoT microcontrollers and development boards to Mini PCs running Windows and machine learning devices. They were kind enough to send me their new Wio Terminal to use it in one of my future projects, but since that will take a while, I just wanted to write a quick post about it. This device would be the equivalent of an All-In-One computer, at a microncontroller scale....
