CreeRelays Project (part Cree bulb, part Arduino)

[ogiewon]

I am not sure how much current the Cree Zigbee module consumes. That would determine whether or not it could be run using a battery.

You could obviously use just the Cree Zigbee module all by itself, without the need for an Arduino or ESP8266, which would help to reduce total power usage. However, the original lightbulbs are designed to be powered by 120VAC at all times. I also believe the Cree bulbs are Zigbee repeaters. Usually, battery powered devices are not Zigbee repeaters due to the increased power usage.

You may want to consider using my ST_Anything project which offers a direct LAN connected solution, bypassing the need for Zigbee altogether. It really depends on what your specific requirements are for what would work best.

[DEPRECATED] ST_Anything - Arduino/ESP8266/ESP32

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 …
