Not a Homey question... but need some help. Fibaro, perhaps ...

My bathroonm 12v LED lights are switch on/off by a Fibaro FGS-222 relay. I can operate the lights manually via a switch or via a Homey Flow/web interface. No questions here ;-)

It looks like this:
The moment I press the wall switch (or a slider in Homey), it takes about a second for the lights to come on. Probably because the 230 to 12v trafo and the 12v dimmer first need to power up. The dimmer is built into a cupboard in the bathroom. I can change the level manually, but it is a hassle

Anyway, I would love to be a to set the dim level via Homey. So, still be able to switch manually , but also be able to set the dim level. What would I need to achieve this?

I don't know the type of trafo you are using and in particular if it is able to be dimmed, but it should be possible to replace the fibaro switch with a fibaro dimmer-2...

I have several 12V powered lamps, with external 12V trafo... which are now dimmed by the fibaro dimmer-2's...
In some cases, I had to replace the trafo by another 12V trafo that was capable to be dimmed...

Interesting! I will check if the trafo is dimmable! I emailed the shop with this question.

@Eternity I'm not a techy, but In my kitchen I have the same situation. So I tried to find a solution but came to the conclusion that it's not possible to dim, via any kind of device, at the primary 230V side of the trafo to achieve what you (and myself) want. All dimmable led lighting 230 > 12V DC is dimmable at the secundary side of the trafo. But, real technicians at this forum, please correct me if I'm wrong. And give @Eternity and me the right solution...... Thanks!

But (edit) ...... I have the idea that placing a Qubino 0-10 V dimmer zwave+ at the secundary side could be a/the solution. And then comes the question about pairing with Homey. I donot know yet.

The shop I bought the trafo from, also sells dimmable versions. 

Unfortunately, the relay switches a Led strip with one relay and two led lights with the other relay. In your link, those are two different type of trafo..... 

Anyway.... Let's first await the response from the shop. 

@JanH
Seems like a solution is possible!
