How to correctly install a Fibaro Dimmer 2

Hello Hubitat!

I am moving here from ST. The first thing im trying to install is a Fibaro dimmer 2 module. I have a bunch of them, so i would like the first one to be installed perfectly before i start the bulk work.

What i did so far is buy an Aeotec stick and install Silicon labs. I managed to install the Fibaro module without security to Hubitat. I can turn the lights connected to the Fibaro S1 on and off using either the physical switch or the hubitat app. But i cannot seem to figure out how to use the S2 of the dimmer. I cannot find it when i use button controller, or webcore. Also if i click on the physical switch there is nothing visible in the log files. I tried 3 different drivers.

Any help would be very much appreciated!

By changing a parameter i was able to switch S1 and S2. This ofcourse is not useful, but it does tell me that the button itself works.

It's funny I was just thinking about this earlier today wondering if there's a custom driver that exposes the S2 input. I have the Fibaro 2 behind every light switch and it would be good to use that spare input in automations.

@j.sonnega82 - I just had a look and found that there's a community driver available by CJ Charles (if you have HPM installed just search Fibaro Dimmer 2 and it comes up). In that driver it uses the scene associations so that S1 and S2 events are exposed as button presses. You can then use those button presses in Room Lighting, Rule Machine, or Button Controller to fire off whatever action(s) you want.

I will look into that. I was just looking at the scene id's myself. I have set parameter 28 to 1. Now when i press the physical button i get a sceneID in return. I see it in the log file. S1 and S2 give a different ID. So it seems these are usuable, i just cant figure out yet how to use them in webcore.

So it sounds as though if you use that driver I mentioned, those sceneID's will be returned as button presses instead and then you can use those in webcore.

I am trying out the driver you mentioned, Fibaro Double Switch 2. I see 2 sets of on and off buttons now. I want to turn on a light when i press the physical S2 button. When i click the button, and check the log files i see this: Unhandled event SceneActivationSet(dimmingDuration:0, sceneId:21). Theres nothing about button presses. And in webcore i have no idea how to use the sceneId.

I've not tried it myself but @cjcharles may be able to assist/advise. The original post in which the driver is detailed is closed for further comment:

Double switch 2 is a different device... You need the Fibaro Dimmer 2. Maybe thats the problem here?

I’m confused :confused: The driver I posted the link to is for Dimmer 2 not Double Switch 2. In HPM you have a driver for both of the devices. The op is wanting to use the S2 input of the the Dimmer 2 device and from reading the linked post that seems to be possible with your driver for Dimmer 2 (unless I’m mistaken)
