Hi all, i’m sure it’s been asked before but searches haven’t revealed an answer to my specific question.
I’ve got some Non-Dimmable LED lights that i’d like linked in to ST. The Light Switch has no neutral. Ideally i’d just like to place a Relay Module (Qubino/Fibaro) behind the switch but from what i can see they require Neutral, leaving my only easy option as being the Fibaro Dimmer (I know Lightwave is possible, and also pulling a neutral, but i’d rather avoid them).
So question is, can i use the Fibaro Dimmer to just send on/off commands to the LED lights? Anyone else got this or a similar setup?
Thanks all, sounds perfect for my needs I could change the bulbs but they’re Soffit lights on the front of the house which i don’t really want anywhere inbetween off or 100% on
You might need a bypass for installations with no neutral… Basically if you see the LEDs dim very faintly when they should be off, you will need a bypass.
Cj could you elaborate on bypass please. I have just installed 9, 5.5w led lamps, the room has 2 dimmer switches. One is a Lutron Rania universal dimmer with a 50w min load and certified for low energy lamps, the other dimmer i have to change to led compliant but not done yet. The issue i am currently seeing is as you describe, 2 of the lamps stay lit very very dimly when they should be off. What is a bypass and from where ?
I would suggest not using the Fibaro dimmer bypass for a Lutron dimmer, they are very simple devices consisting of a resistor and capacitor/inductor, but they are likely to be specifically tuned to the dimmer of the chosen manufacturer. That said I’m sure Lutron will make one…
Last question, have you installed with a neutral? If you have a neutral and they are still glowing (which is possible since most dimmers pass some current through the load just to check it is connected), then it is likely that you have bad quality or incompatible bulbs. If so then changing the bulbs and experimenting with some brands is probably your best bet.
Thanks guys. I am in the Uk not too far from Rob actually and know Vesternet well so thanks for that.
The dimmer cj was installed years ago by somone else so i have no idea if it has a neutral. I will look into contacting lutron to see if they have whatvis needed. The lamps themselves were purchased from toolstation and at the time i had no idea things would be so complicated, from a simple lamp change to changing dimmers, adding load thingys, matching lamps to switches… what a work up.
No mate, pre installed and not even on a platform yet. waiting for the Echo plus to see if it can get a connection to the switch, i actually thought for a very short time the Lutron switches were viable options for Uk home owners to have a WAF connected switch… until i saw the prices !!!
Just replaced the lamps, got informed the lamps were staying on and saw this post
I think I follow now having reread! So swapping the bulbs triggered the problem with a Luton controller that was already there. There is another circuit but that is totally different and separate for now. Sorry that took me so long!
You say it only happens on 2 of the 9 spots. Can you try swapping those two, firstly to see if moving the two bulbs moves the problem (in which case it may be easier to claim those bulbs are faulty and replace)? Second, with this bulbs not connected did it cause a problem for other bulbs?
It varies on which lamps stay on. Perhaps it is residual current which needs a load . The lutron switch does have leds on the face to indicate luminance value maybe even that is sending enough current to light random lamps when off
Ah ok, yes I expect in that case that the Lutron is passing a current in order to detect dead loads and circuit problems. That said if you change the low-end trim on the Lutron dimmer you should be able to fix it without needing a bypass.

will have a look into that Cj thank you, i knew it was adjustable low end top end and speed of fade but didnt think that would help. its a different switch shown but the principle is worth investigating
