RGBW analog led strip w/ ESPUrna + MQTT

Hi,

yes, I want to control RGBW + brightness from OH sitemap.
Send RGB or HSV via MQTT.

EPSUrna root topic:
lights/livingroom/rgbw

On ESPUrna you set up root topic for that device
mine is “lights/livingroom/rgbw” so rgb set topic would be “lights/livingroom/rgbw/rgb/set” and state “lights/livingroom/rgbw/rgb”

I have succeeded with this but in log I can see it does not send round values.
Also cannot get full brightness, only up to 100

I think ESPurna outputs 24bit values (figured out googling)

Thanks,
G.
