Flash Hue Lights when Garage Door Opens

#1

Would like to flash my Hue Lights when the garage door opens. I have a ST sensor that tells me when the door is open.

I thought this would be simple, but when I do

If Garage Door Sensor Changes To Open Then
Flash Lights

But i can the lights to flash using the built in method to flash.

Please post your piston screen shot, also set logging to full and paste some logs.

Are you using the stock HUE DTH? If you use HUE B Smart DTH (https://community.smartthings.com/t/updated-december-2017-hue-b-smart-groups-scenes/95397) @tmleafs has coded a builtin flash command into it so that webCoRE can trigger it with “flashcore” instead of the emulated option built in.

Ultimately both are being emulated in the cloud… either by the device handler or webCoRE, so it makes little difference.
