I'm new to hubitat and not sure how to troubleshoot these things yet. I have 6 Sylvania lightify RGBW bulbs connected to my hubitat set to turn on with motion control in the bedroom and contact sensors in my stairs going down to the garage. Everything was working mostly ok until today (the bedroom had turned on yellow or purple a couple of times and the landing orange but I changed the colors back and that seemed to fix it). Both the bedroom and the landing are now turning on at 50% dim when the actions are triggered. I hadn't changed their states to dim prior to this, I'd only had them set to 100% brightness and the rules were set to turn them on as a switch. I tried changing them to turn on as dimmers and set the level to 100 but they both still turned on at 50% even after changing their states to 100% and turning them off. I have them all set up as a group 3 lights in the bedroom group and 2 lights in the stairs group. What should I provide (and how do I get to that information) to figure this out?
I am having the exact same issue, and was about to post something about it. Seems like if the lights are already on, the dimming will work, but if they are off, the dimming is overrridden by something that takes them straight to 50%, no matter what.
I am running commands that are simply "set dimmer to 100%," and that command turns the light on, which immediately sets itself to 50%. Did you ever get a solution, or does anyone else know a solution to this?
If anyone wants to help solve this, I've done some further testing, and I have a workaround for OP (though I'd prefer not to have to use this hack myself):
FIRST, the additional findings: if you use ANY MEANS of turning these lights on by sending a dimmer command, AND the level you send is over 50%: The lights will turn on and dim directly to 50%. For example, to test:
Using the dashboard with the dimmer template so you can jump directly from off to a certain percentage with one click:
LIGHT IS OFF:
Click 23% --> Light turns on, dims to 23%
Click 88%--> Light turns on, dims to 50%
Click 49%--> Light turns on, dims to 49%
Click 100%--Light turns on, dims to 50%
You get the picture. Doesn't matter what percentage the dimmer is set to when the light is off...It will dim UP to 50, it will dim DOWN to 50. If the command sent is 50 or more, is sets to 50.
Strange behavior, and I'm wondering if this is in the driver, or something in the firmware of the Lightify controller itself (and if so, WHY?, and I wonder if it can be flashed to fix this?)
The workaround:
In your automations, send 2 commands: 1 switch command to turn it on, 1 dimmer command to set the brightness. You have to put a 1 second delay on the dimmer, to give the light time to receive the dimmer command in an already-on state. It MIGHT work sometimes without the delay, but it wasn't reliable for me.
Anyone wanna take a look at this, or is it a known issue?
UPDATE: Looking at this FAQ about the devices makes me think it may be something about the default mode. I can confirm that if I cut power to my lightify strips, NO MATTER WHAT they were set on before I cut power, they turn on at 100%, not 50%. However, it says you can change the "Default mode" in the app with their gateway ($19), so...it might be worth a shot? I don't think that's what's causing this, but who knows...
Thanks,
