Dimmer for 220v spot led dimmable

---

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

@Zacca i know. And i am trying to tell you that that is not possible.

How would pimatic know that you have switched it on by hand? It cant. Unless, like i said, you use a wifi switch that tells pimatic it is on or off.

That is why i suggested you also use a 433 mhz switch as a workaround…

I have done my best to explain it, and it should get you to what you need.

Goodluck

@Gleno0h Yes thanks, I know you mean well

220v —> dimmer -----> contact button to gpio ------> light
This way you think works? It should be good for me. The problem is that the switch 433mhz does not match with the rest of my house switches (bticino)

@Zacca why do you want to dim a contact and then lights… That makes no sense.

220v to this switch : https://www.klikaanklikuit.nl/nl/producten/acm-1000-ingebouwde-schakelaar.html and that switch to the dimmer and the dimmer to the lights.

Learn the switch to pimatic, put power on it, enable switch from pimatic to give the dimmer power and let the dimmer dim the lights. Idk why you want to use the GPIO, doesnt make sense to do what you want to do.

Wall switch by hand -> 220v on -> switch kaku -> dimmer 10% -> lights. Period. Do it like that.

I am using the AWMD-250 dimmer to switch/dim 4 GU10 5W LED spots via a homeduino + 433MHz transmitter. Works great, except for the occasional flicker.
It is possible to connect a normal wall switch to it, though when you switch it manually the state in pimatic will not be updated.

@Rene-Arts exactly. But he wants to dim instantly to 10% after switching the power on, so pimatic has to know the state, thats why i suggested a switch. Seems logical to me.

If you would switch it on manually, it restores its previous dim state (so if it was switched off while dimmed to 10% it would be just fine). With pimatic it is possible to directly send a dim to 10% command.

@Rene-Arts said in Dimmer for 220v spot led dimmable:

dim

Ive put the dimmer on 50%, flipped the wall switch and doesnt go back on so no, it doesnt. Atleast not the kaku dimmer.

@Gleno0h But in this way, from what I understand, if I have to restore for an emergency, from 10% to 100% can not do it manually. Right?

@Gleno0h Are you using the AWMD-250 as well, and have you connected it properly? With the wall switch connected to the two white wires? When you put a switch in series with the dimmer it doesn’t work as it should.

Hi,

I found this wifi dimmer (KingArt):

(This picture says it can not dim led bulbs but some others can…)

Has anyone experience with this one?
Can it be flashed with Tosmota?

Thanks in advance…

Bump…

Would be very nice if this works…

@lschip no experience and it should be supported by tasmota;

Great, thanks!

I did a lot off googleing but I didn’t find it.
I’ll give it a try with Tosmota,
