My Home Automation Addiction

Strip the brains out of the bulb, connect it to a servo and gear box designed for my blinds. Connect it to the Hue Bridge as a dimmable bulb.

This brings back memories of an old project that I created, but never actually used…

I like your ingenuity!

CreeRelays Project (part Cree bulb, part Arduino)

All, I was inspired by the work of @drbudro which can be found here… I decided to see if I could possibly build a generic DeviceType and Arduino Sketch that could make use of the Cree Connected Bulb’s easy-to-extract Zigbee module. By reading the dim level values into the Arduino , I was able to accurately obtain 100 discrete dim level values. These can be used by the Arduino to perform any action desired. This example implements an 8 relay controller. The Groovy Device Type code works, but does not expose all 8 relays as separate virtual devices (which is always the 1st question people love to ask! ). Also, this is essentially a one-way communication device. SmartThings can command any one of the relays to be on at any given time, but the Arduino cannot send any da…
