Steve,
I assume you’re considering using the Zigbee board inside a Cree Conencted bulb, correct? If so, you may find an old proof of concept project I did a few years back interesting. It might be a decent starting point for your project.
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!
Additionally, these days most folks are preferring to use inexpensive NodeMCU ESP8266 boards (~$9 on Amazon) for connected custom projects. You could very easily look into using my ST_Anything project which supports a variety of sensors and devices.
UPDATE 2022-08-17 - Per this recent SmartThings announcement, the Groovy IDE will disabled on September 30, 2022 . My best guess is that any existing ST_Anything devices will probably cease to operate at this time, or shortly thereafter. It has been a good 7+ year run for ST_Anything users. I want to thank you all for making ST_Anything a successful project! My son and I really had a lot of fun creating it together, and have enjoyed hearing how you have all used it in so many creative ways.
As many of you probably already know, I have moved on from ST and have ported ST_Anything over to Hubitat as “HubDuino” . If you have devices running ST_Anything that you ‘can’t live without,’ at least you know you have options. Another option for ESP8266/ESP32 users would be to use ESPHome along …
