Smart trees may soon come to mean something more than a fashionably decorated tree. Forging ahead with this new definition, [Ayan Pahwa], with help from [Akshay Kumar], [Anshul Katta], and [Abhishek Maurya] turned their office’s Christmas Tree into an device you can watch live!

As an IoT device, the tree relies on the ever-popular ESP826 NodeMCU — activated and controlled by Alexa, as well as from a web page. The LEDs for the tree — and the offline-only tree-topper controlled by an Arduino Pro Mini — are the similarly popular Neopixels.

For those viewing online, a Raspberry Pi and camera have been attached to this project to check out the tree’s lighting. To make that possible, [Pahwa] had to enlist the use of ngrok to make the Pi’s –normally — LAN-only camera server accessible over the internet. The aforementioned web page was coded in Javascript/CSS and hosted on a server running an instance of Ubuntu 16.04.

If you’re looking to adapt this project to another idea, the github page has all you’ll need while you wait for next ’s Christmas harvest. What’s next, smart ugly Christmas sweaters? Smart ornaments?
