Fibaro Dimmer 2

Oops, I published your amended Device Handler. It appeared to work for Rooflight 1, but not for Rooflight 3. I have two in the same room, configured the same, just one has a Dual Relay called Rooflight 1 and the other Rooflight 3.

Also, I have dual relays turning on and off Towel Rails. So changing to your latest code isn’t what I want for these :-).

I am going to change back to the original Dual Relay DH code, and stick with trying to get WebCore working for now!

thanks for all your help. Helps me learn!

David.

I’ve added parallelism, but unfortunately Switch 1 and Switch 2 don’t turn off after 40 seconds (they don’t turn off at all). Probably just needs a tweak somewhere.

Here is my latest WebCore coding:

Fixed it! Seems it was case sensitive. I had ‘On’ with a capital ‘O’. Changing it to ‘on’ has done the trick. It turns off after 40 seconds. Thanks!

I’ve just reinstalled a Fib Dimmer 2 thats been hanging around. Not bothered with switch so connected common to the output (squiggly line) and Live to L. I’m contolling 12 x 3w LED’s . I can dim but they suddenly go off. I think its a voltage issue. Any ideas?

Do you have a bypass module installed? Typically required if the total load is less than 50W.

Alternatively, it could be the bulbs themselves.

No Bypass would be just under 50W as well. Cant get into the ceiling to fit bypass, I believe you need to get to neutral. Is it poss to fit at the switch for a no-neutral (UK) fit?

Thanks for that tip but it came back “Load Fault”. Is there a fix?

Sorry just checked they’re actually NOT Led’s they are 30w (I think) incandescent standard bulbs. Is my wiring correct (I’m not using a switch
Just straight into module) - common to the output (squiggly line) and Live to L?

Ok, Ive taken half out so now 180w Ive put the loop in and still get overloaded.


Thanks for advice.

Yes I appreciate trim the copper. It was merely for a test. The permanently Live (Via a tester) is in “L” The other cable (switched live) is into the output (switched live). Ive tried them the other way around and the result is identical. I have tried with one bulb only and separately with a few LED’s in. Each time doing the re-calibration and each time with the same Overload error. Could the unit be faulty perhaps?

Is the Neutral the group on the right that are black? If so I will use them.
Also I tried another module and it worked fine!
I’m going to add 10 x 4w LED’s. It says the minimum rating is 50w, however am I likely to get away with 40w?
Thanks.

Thanks for that information. If I have Neutrals I can use the bypass without a problem.
Factory reset says that you hold down until yellow glow. There is no yellow glow…

Fibaro also responded advising to increase #39 to 350watts. I haven’t tried it as I found another solution.

Very true. And like you say that wasn’t problem anyway.

Hi everyone !

I’m struggling with the dimmer giving me “Voltage Error” from time to time. Is there a way to ignore this? I have to go into the app and “clear” to make it function again with motion detector.

I’ve tried the DH “Fibaro Dimmer 2 ZW5” but went over to DH from codersaur. No difference. If I go lower on Parameter “max brightness” I will end up with less light output.

Seems like I have firmware 3.05. The latest one is 3.5? Can’t seem to find a way to firmware upgrade it without a Fibaro HC :frowning:

Anyone that can help? :slight_smile:

Thanks Robin for your kind reply.

LED strips upwards to 50W run by a dimmable quality LED Driver supporting dimming by both leading and trailing. LEDs are 12V. I installed it by a 2 wire config, see pic attached. I had to manually config the load type from trailing to leading to avoid “Surge error”. But now I get “Voltage error” instead. I switched from Nano Dimmer due to flicker but now I run into a totally different issue (flicker is gone with Fibaro).

If you have any tips I’ll be super happy.

Yes the white wire goes straight to the 230v-12v driver which the strip is connected to. All was connected before calibration.

Is the RGBW module is made for LED strips while the Dimmer 2 is just for led spots and other 230v units? Perhaps I’ll have to swap it for this unit. I didn’t know it was necessary. I tried googling and I can only find how to connect using a RGB strip and not a normal strip. Do you know where I can source the correct setup? The manual describes the RGB strips only.

Thank you!

You’re the best Robin!! I’ll purchase the controller and reply with my experience :slight_smile:
Thanks a lot!

Here something from Fibaro manual:

F) VOLTAGE DROP ERROR
Appearing of an error in a 2-wire connection may be the result of mains voltage drop or a too high brightness level of the light source.

If parameter 37 is set to 1, the device will automatically try to turn on again. Low voltage error suggests that parameter 2 value should be reduced until disappearing of the failure. You can also recalibrate the L-load using parameter 13.

Parameters:

  1. Maximum brightness level (parameter is set automatically during the calibration process)
    The parameter can be changed manually after the calibration.
    Available settings: 2-99 - percentage level of brightness
    Default setting: 99
    Parameter size: 1 [by

Thanks. I did try to lower the Parameter 2, now it’s at 61. If I go lower the brightness goes down. I can try a couple more values to see, but for some reason I haven’t had an error since my post. I’m pretty sure it’ll come back if I don’t change something.

I got a brand new RGBW controller from Amazon but it’s dated back to 2015… Do you know if the firmware has changed a lot since then as we can’t upgrade without a Fibaro HC?
