Fibaro dimmer 2 (fgd 212) with dual lights

(hyeung) #1


I currently have a 1 gang 1 way switch that controls 2 ceiling light fixtures.
Assuming that the combined total load for the 2 lights is within 250watts, would there by any issue in wiring up the dimmer 2 module on the 1 gang 1 way switch that’s connected to the 2 light fixtures?
Just want to check that’s there’s no limitation with the dimmer module when using under such configuration of additional light fixtures wired up to the same circuit?

Assume the dimmer could dim both light fixtures as if it were one.
The light fixtures are identical, powering g9 bulbs. I have 2 rooms in this setup. One room consisting of 2 ceiling fixtures with x5 g9 bulbs per fixture; and the other room with 2 ceiling fixtures with x10 g9 bulbs per fixture. Both rooms controlled by a 1 gang 1 way switch.

If I change the bulbs to reduce the total load to be <250w, could the dimmer by used in this type of setup?

Yes, as long as total load applied to each Dimmer 2 is below 250w (and all the bulbs are the same and dimmable) it will work nicely.

Don’t forget to take advantage of the second switch input on the Dimmer 2, it won’t control any loads directly but is handy for scene / routine activation through the hub. When replacing a single gang switch, buy a 2-gang.

@zcapr17 has recently published a great device handler that massively improves on the ones that came before.

That new handler from David looks great! Like the sound of child protection and night mode features built in…plus lots of other features on top…not sure what they all do.

I’m still using the previous handler that you suggested last time. Will switch over and give it a try!

You know if there’s a similar one for the double switch 223?

For the dimmer 2, would it be ok if the total load is exactly 250w (but not less?). These fixtures consist of 5x g9 @ 25w; with 2 fixtures giving a total of 250w. All controlled via a 1 gang 1 way. Or would I need to drop the bulbs to 20w instead giving 200w total.

There isn’t a similar DH for the 223 (yet)… tagging @zcapr17 lol

Night mode wouldn’t be relevant to the 223 though (no dimming function) and child protection / direct association between zwave plus devices can be turned on using @zcapr17’s zwave tweaker DH.

You’ll probably be ok dead on 250W, I’m sure there’s a small margin of safety.
