Qubino dimmer minimum load
« on: January 06, 2019, 06:56:38 am »
I have several Qubino Flush Dimmers, and for the most part they work fine.
However, in our living room, we have a dimmer that is connected to only one light. That light has one 9 watt LED bulb which is dimmed to approx. 4.5 watt to get the desired light setting.
We experience issues turning on this light. I understand that starting dimmers at very low loads is a common issue, but I was wondering if there is any smart way to solve this?

If we turn the dimmer all the way up to 100% it will start. For scenes that are triggered within Vera this is solved quite simple by setting the dimmer to 100%, waiting one second, and then setting it to 30%.
Our problem is that this light is quite frequently controlled by a wall switch. Is there any clever way to make the dimmer start at 100% when the wall switch (I1) is pushed?
If I can get it to start at 100% it should be simple to create a scene to dim it down to the desired level.

I've experienced the same with LED bulbs. I've solved it by replacing the bulb. Its a huge difference between LED bulbs and a lot of really poor once out there.

To be honest; I've had my rounds with cheap LED bulbs.

Does anyone know if the Fibaro Bypass 2 will work with Qubino? They are both trailing edge, so I guess the Bypass is a simple devise that is not really Fibaro specific?

My bulb is a high quality Philips Globe LED. This bulb gives a really nice light (compared to several others). If I'm changing the bulb I think I will be going back to Halogen to avoid buying 10 different LED bulbs to find one that gives high quality light _and_ will start at the desired light output which I guess will be difficult given the low-energy nature of LED and the fact that there is only one bulb connected. Not too concerned about power consumption, but it's always a hassle with Halogen when the bulb burn out, especially for non-standard bulbs.

Might just end up buying a Fibaro dimmer (with the bypass) and use the Qubino somewhere else.

Bypass's are not the exculsive domain of Fibario etc.
If you are in the EU look for a TEM Bypass IA50, much cheaper....
spec at the link below.
