Fibaro 212 installarion


#1

hi all,

trying to install the fgd 212 , i wired as per setup and all the light does is stay on all the time

i can see a very feint green light on the fibaro

some pictures of my wiring and how i wired it

red went into L and black went into the far right

I initially had a dimmable bulb in and it flickered so i swapped it out for standard bulb

i had no cycle happen they just stay on all the time

any ideas what i have done wrong?

Looks right. I take it that Red and black used to be across com and 1WAY? Can you confirm that Live is indeed Red and Black the switched return to the lamp?

After connecting the power, does the LED do anything before going dim green. Do you see it glow red for a while first?

Green light is a good thing after powering up… means auto calibration was successful.

The reason it stays on all the time is because you have it connected to a toggle switch whereas the default setting expects a momentary switch.

  • Put the hub into inclusion mode (add a new device)
  • Triple click the b button on the Fibaro whilst
  • add the advanced handler to your online account, linked below, and assign it to the device.
  • back in the ST app, view the device, click on the cog symbol and change parameter 20 to 1 (toggle switch)

  • as you have changed the lamp, you’ll also need to force a re-calibration (parameter 13). The flickering you saw was due to your 2-wire setup, you need to add a Fibaro bypass module across the load and then that will go away.

yes red was to com on original switch i have reverted back just so i can go to bed later:-)

ah ok - maybe i didn’t do it wrong then - surprised myself - i saw a video and the light was supposed to flash and cycle through a test - i didn’t see this so presumed it was wrong

is the b button the one below the green light on the fibaro ? i thought it was as its the only button i have noticed so far

ill download the handler now and try again

i thought about the flickering - i was using a dimmable IKEA smart bulb - if i use a standard (more watt) bulb i should not need the bypass module as watts should be enough - if i am right in thinking - would be shock - twice in a day

It’s unlikely a single lamp on 2-wire circuit can do without a bypass, but always worth a try. Even if you loose the flickering it will still have a noticeable glow when turned off, as it needs to run a small current to power the module.

Yes, that’s the ‘b’ button.

When you say ‘smart bulb’ what do you mean? If you have a ZigBee or such like lamp, then that won’t work, it need to be a ‘dumb’ dimmable lamp.

Edit: just to be clear when I say ‘dumb’ that can still be a electronic lamp like a LED, it just can’t be ‘smart’ IE ZigBee, z-wave or WiFi these must have full voltage 24/7 and then over data they dim up and down. A fibraro dimmer is a phase dimmer so reduces the voltage to reduce the light output.

If a light flickers it is usually because your using a none dimmable lamp and you a stretching the driver to work harder than possible to keep the lamp voltage the same (that’s it’s job). If it hardly dims or jumps from 100% to off this is usually because the load of the lamp is smaller than the dimmers minimum capabilities, that’s when you need a bypass. This is hightend when you don’t have a neutral at the switch, as it gets a potential difference from the higher load of the lamp and so can’t run its self.

I keep a set of good old-fashioned incandescent and halogen bulbs for testing. This way I can see if the low energy bulbs are causing an issue. As Robin says all you need to do after a bulb type change is re-calibrate.

Do you have a old 60w build you can use to prove your setup is correct?

got installed and registered in ST

when i put a lap 4w led bulb in the light stays on all the time really bright and i couldn’t pair and switch did nothing
when i put the ikea 12w smart bulb on it just flickered feintly and no pair and switch did nothing
put in an older led 11w bulb and it was very dimly lit but allowed the pairing as the light on the fgd212 was bright green - prior to this it was feint and flickery and now turns on and off via the switch

just need to find the correct bulb to fit or add the fibaro FGB-212 Bypass 2 Dimmer and use existing bulb

4W is pushing it lol… using a bypass will get you down to 5W, without a bypass it’s 50W.


#11

ive ordered the bypass should be here tomorrow

will see how to install and hopefully should be sorted

Here’s a diagram I made earlier:


#13

Got bypass fitted and new 10w bulb

But seems very dim not as bright as before but all works
Any suggestions to improve brightness
If I plug the bulb into normal light socket I get double brightness


(Robin) #14

You need to re-calibrate to the new bulb… assuming you are using the advanced handler I mentioned above:

  • View the deivice in the ST mobile app
  • Click the cog symbol for the settings page
  • Change parameter 13 to 2
  • click done
  • light should phase up and down during the calibration process, give it a few minutes to settle down
  • Go back into settings and change parameter 13 back to 0

You can also manually tweak the max brightness setting using parameter 2, but best to let auto-calibration do its thing.


#15

think something is not quite right

i can edit the settings - param 13 to 2 click save (not done) and then nothing happens - it says updated and that is all

same for all settings

Log into the IDE and then go to the live logging tab, with this page open, try the app controls again and watch for any error messages.

Specifically, look out for anything related to security encapsulation.

Also, does the device show sync-pending?

clicked on the app and tried to change the brightness

how about on/off
