Dimmer for 220v spot led dimmable

---

In my house under construction would check three rooms with led lights 220v dimmable through raspberry. Someone using a dimmer? If yes, how? With what hardware ?

@Zacca maybe the kaku acm-100?
It has a dial to select your lightbulbs

I use that too, but a warning: it’s very sensitive to variances in the utility-frequency. Here in NL we still have tone-frequency switching of equipment (generate a higher tone and embed that into the 50Hz line) and whenever that tone is present, I see the LED’s on the ACM-100 flicker.

For the rest, the receiver is good! I placed it inside the stainless steel base of the lamp,and it never missed a command.

Thanks for the answers. If possible I would like some other answer. According to you it is possible to mount it in a traditional room with 6 led 5 watts dimmable and 2 wall relay for the on-off ? My ultimate goal is to create a rule like … If it’s after 22.00 and before 7.00 when you turn on the “LED” power is 10% else 100%

Who do you mean by “you”?

Please take a look at the following page to see the working dimmers known to the community;

In order tot use a slider to dim, you need a device that is in the dimmer section.

Then, it is up to you to see if it supports your device.

As long as your led bulb support dimming, there shouldnt be a problem.

Kaku is quite expensive compared to others like ELRO, but elro dims by pressing on three times, you dont want that, trust me. Buy kaku.

Excuse me, I use google translator to translate. I have not checked the translation that does not seem to have worked well.
What I would better understand it, since I have never used the radio controls, though when I turn on the lights with the traditional wall relay, the lights can be switched on with a different power according to a rule of pimatic. Sorry but I do not speak English well and would be difficult to even explain it in my own language.

@Zacca
I think your question is that if it would be possible to use a wall dimmer, a dial knob, together with a 433mhz dimmer?

Wall dimmer -->> 433mhz dimmer -->> light bulbs?

If so, im not sure if that works.

No, sorry.
What I have to do is…
Wall Relay —> radio dimmer —> led
When the wall relay turn on ask pimatic for percentage power of dimmer.
If it’s 7.00 am when I turn on the wall relay, power of led is 10%
If it’s 9.00 pm when I turn on the wall relay, power of led is 100%

@Zacca ah i think i understand.
Possible? No. A wall relay does not send out any signal so pimatic cant see if it is on or off.

Mostly all wall switches, that are 433mhz, do NOT send their state(on/off).

An option would be to use wifi switches.

Power off -> ping the switch, no response
Power on -> ping answer -> do action

WHEN its 7:00 and wifiswitch is present THEN set YOURDIMMER to 10%

@Gleno0h uhm thank but I thing isn’t a good solution

And…
Raspberry Contact button ----> Switch 433mhz On -----> pimatic rule than put ON dimmer to 10% ------> dimmer 433 mhz ?
Is it possible?
Or directly…
Raspberry Contact button ----> pimatic rule than put ON dimmer to 10% ------> dimmer 433 mhz ?

@Zacca what do you mean by raspberry contact?

A power socket/contact on the wall, normal or a 433mhz, does NOT send their state through 433mhz.

If you use a dimmer it will be in this order:
Wall contact --> 220/230v --> 433mhz dimmer --> lights

So yes, your wall contact is always on. Pimatic cant see if it is on.

Then you can execute set lights to 10%, which then gives a signal to the 433mhz --> 10% power on lights.

The 433mhz always has to have a current to work.

As you see, you just cant “see” if there is a switch turned on and then base a rule on that.

What is your native language? Dutch? German?

EDIT;;; Oh sh*t i think i finally get you…
You want to set the percentage when you turn the light on through wall contact?
So: contact on -->> set dimmer to 10%. If so, above still applies, pimatic wont see the state.

@Gleno0h Ok thanks, now i have understand
I’m italian

@Zacca i’ve looked around and maybe the following is possible.

Buy this one; https://www.klikaanklikuit.nl/nl/producten/awst-8800-draadloze-wandschakelaar.html and one of the dimmers on this list from kaku; https://forum.pimatic.org/topic/35/supported-devices-plug-and-play

The device page tells us that the wall switch is recognized as switch;
KAKU / COCO AWST-8800 Switch 1

This would mean that if you toggle the wallswitch, a switch goes to on in pimatic. You then can use a rule.

WHEN kakuswitch1 is on THEN set kakudimmer1 to 10%

@Gleno0h Hmmm sorry but I do not like to switch, I would like to mount the same buttons in each room.

Maybe it is a stupid question but,
If the dimmer is always connected to 220V, I can set it to 10% with 433 mhz, even if the lights are off?

With lights off
WHEN it’s 8:00 to 20:59 THEN SET acm-100 to 10%
So when I turn on the light, the dimmer switches on at 10%
WHEN it’s 21:00 to 7:59 THEN SET acm-100 to 100%
So when I turn on the light, the dimmer switches on at 100%

@Zacca for that you want:
220v --> 433mhz buildin switch --> 433mhz dimmer --> lights

WHEN 433mhzswitch is on THEN set 433mhzdimmer to 10%

And for off

WHEN 433mhzswitch is off THEN set 433mhzdimmer to 0%

So, now if you switch the switch to on, the dimmer should go to 10%.

or maybe esp8266 solutions. but those are wifi based chips …
there are ready built solutions.
check this thread here e.g. for maybe getting a clue
https://forum.pimatic.org/topic/1257/wifi-switch-to-integrate-in-wall

@leader21 thank you but I have no problems to wire the switch
surely I’ll use it for other things

@Gleno0h Finally I found the manual in Italian acm-100
There are two ways to connect:

1. 220v -> Switch -> acm-100 -> lights
   or
2. 220v -> acm-100 -> Switch -> lights
   in the second mode the dimmer is always powered, then
   I should send him quietly commands (power sets to 10%)
   when then turn on the lights, the dimmer in this way is 10%.
   Anyway I ordered one and I will update

@Zacca if you use method 2, you are going to cut the power to the switch. That makes no sense. You might end up with breaking your hardware.

220v --> dim 10% --> switch not enough power to operate --> lights wont do anything.

Do as method 1 but keep in mind that your switch also has to be 433mhz!

That way you can make a button in pimatic to turn the switch on(and thus pimatic can see that it is on), and then by rule you can set a dimlevel IF switch is on.

The rule would be something like this for example:
WHEN it is 17:00 and switch is on THEN dim acm-100 to 10%

@Gleno0h
I’m sorry, I think there’s been a misunderstanding on the switch that I thought to use
The switch that I said is the classic Hand-operated button ON OFF
ON (the electric current passes), OFF (break contact)
It does not need the power to activate
