I have ordered two Gledopto ZigBee controllers and will try the DTH. In the meantime just wanted to let you know what I did with my Wifi LED controller to address the same issues.
Using MagicLight Wifi, the RGBWW Light strip was configured. To get only the RGB to light up and not the WarmWhite, I created a “scene” in MagicLight Wifi that set the WarmWhite to “zero” and called it Lincoln. Then when turning on the LED, the WarmWhite would sometimes get turned on. Running the MagicLight Wifi “Lincoln Scene” the Warm White was turned off and the RGB would be 100% red or blue, etc, without any white.
As another option, if the controller was configured as a RGB/CCT, instead of a RGB/WW controller, giving the command to turn on CoolWhite would turn off all white LED’s. This happens because the strip is a RGB/WW and doesn’t have any Cool White LED capability.
To enable the strip to be a WarmWhite and not include any RGB light, I created another scene called Garfield which turned off RGB by setting any RGB color to “zero”. Then the Warm White would be 100% white.
These options that I’m doing with MagicLight appear to be a similar approach to using the Smartthings DTH.
The latest DTH approach definitely looks more efficient and adds granular color controls, so I ordered the ZigBee controller. I’ll let you know how it works.
But, just to let you know I did get the RGB Wifi controller working with Smartthings. I wanted to control the lights via Alexa, so I installed the MagicLight Skill and by voicing the commands the light would change colors. Then to get it integrated with Smartthings and ActionTiles, a virtual switch was created with the same name as the Magic Light skill. Then created an Alexa “routine” which responded to the Smartthings virtual switch and turned the RGB light to either WarmWhite or a RGB color. Now ST/ActionTiles can turn on and off the LED lights like any other device. Giving verbal commands to Alexa will change the colors and or levels.
Looking forward to seeing what the DTH can do with the Gledopto ZigBee controller for my RGB/WW LED strips.
