So I'm back
1st sketch from this topic (with conversion) uploaded to Arduino...and still the same.
Have a look on my debug: 
The last value was a 100% for like 2 seconds - then forced to be 99% and staying like this.
I don't know , maybe I am trying to get something impossible ?!?
@dbemowsk
In the beggining of this topic there are two sketches. The 1st one is using the method which You've pasted. The 2nd one is using Array. I will test 1st one again today later but I'm sure I've tried it yesterday and it didnt work ( I mean still 100% from Domo was Level 99 for node.
Will test again and see where I am.
Thank You for now.
@dbemowsk
Ok
Myself I dont make this conversion.
Unfortunately I dont know how the data exchange between Domoticz-Gateway-Node looks like.
I can see only the communication between Gateway-Node
In my case the dimming values are written in array.
Different way is to do it like this:
analogWrite(LED_Pin[ledid1-1], (int)(currentLevel1 / 100. * 255) ) ;
@dbemowsk
I am not sure what do You mean by numbers to percentage.
I've checked few different led dimmer sketches and all of them behave the same : You move the dimmer bar in Domoticz to 100% but the node receives a value of 99...
I've put the serial print to see the value (array) which is "delivered" to node.
I am writing to a LED pin value LastDimValue-1 but printing LastDim1Value which is then displayed next to the text ON,Level: ...
So again Domoticz bar 100% is displaying here a Level 99 ...
analogWrite( LED_PIN1, dimlevels[LastDim1Value-1] );
Serial.println( dimlevels[LastDim1Value] );
After searching for a solution I finally stayed with code below.

Question to anybody who can help with the last annoying thing
When I move the dimmer bar in Domoticz to a % value - arduino responds with the same % (for example 21% on the screen from serial monitor attached below)
BUT
When I move the dimmer bar to 100% - arduino responds with value of 99 - then it is forcing (sending back an info) to Domoticz and the value on the bar is chaning from 100% (set by me) to 99% forced by Arduino.
Question WHY ????????? 100% in Domoticz = 99% for Arduino ??????
Even changing this line
analogWrite( LED_PIN1, dimlevels[LastDim1Value - 1] );
and removing the (minus) still the same behavior (but I can see on the monitor I am pulling different values from array which is good)
PS. I tried to make the array bigger (like 101 cells and additional 255 value - still showing 99)
@MCF
Thanks for the sketch. It works pretty good. There is this one thing which is not working
It contains
// Pull the gateway's current dim level - restore light level upon sendor node power-up
for (int sensor=1; sensor<=noLEDs; sensor++){
request( sensor, V_DIMMER );
I don't know why but it doesnt save the last dimming status. It's always on 100% after switching ON.
I was trying to implement in your sketch
saveState(EPROM_DIMMER_LEVEL, LastDimValue)
but finished with nothing.
Still looking for solution ... 
@MCF Maybe install an arduino software for raspbian and try to open serial monitor for gateway ?
@mcf
One more thing.
Probably this is obvious for lots of forum users but sometimes I had some problems with some sketches when uploaded to gateway-arduino (connected to Domoticz) and debugger was enabled.
Try to comment out #define MY_DEBUG see if there is any change.
From other side do You need that sketch on gateway ? maybe transfer it to node with nrf24 ?
Hi @MCF
I've just started a topic with two sketches for LED Dimmer. Have a look and test one of two sketches. 1st one is based on Yours with a little change to save the last dimmer status after on/off. 2nd is basing on Dimmable Light sketch (using EPROM to save the status).
Good Luck !
Hello Everyone
Recently I'm fighting with LED dimmer (rookie in programming)
I got to the point where (with help of @Boots33 - Thank You) I have two different sketches both work OK with saving the last dim status but..... only for 1 LED stripe
Tried to implement an array as declaration of additional LED pins (there is a topic on the forum https://forum.mysensors.org/topic/4808/dimmable-led-actuator/6 ) but using this method... I finished with..
1st sketch switching on/off crazy (one button in Domoticz switching a group of lights , some of them not working at all etc.. - >in summarry a mess !)
2nd I didnt even get to the point of few leds - because there is already an array which is a little confusing for me
Q1: Could somebody please have a look on both and advice which one is potentially (better written , less giving problems with multiple pins, I should focus on ?) and help me with declaration of extra pins ?? ( basically I'm trying to use all the PWM pins from Arduino Mega)
Q2: There is already an array in 2nd sketch for the dimmer but I am not sure how it works and why somebody went this way (definition of maxdimlevels and dimlevels array) ??? is it possible to get rid of it ?
Configuration - RPi, Domoticz, Uno Gateway + nrF24, Sensor node nrf24 connected to Mega , mosfets in breadboard (not soldered at all - so no damage) , external 12V for Mosfet Ledstripes -->7,5V Arduino , for testing purpose 6 led stripes connected to PWM pins
(at present disconnected from GND all except 1st one - stripes are very bright and going crazy when not declared in Arduino)

@Boots33 I think I wasn't precise enough.
So below the sketch which is working fine but for one LED stripe. It remembers the last dimmer value.
I 've changed it a little bit. It works better for me to receive and display in Domoticz a % dimmer value info instead of information ON/OFF
send(lightMsg.set(dimmerSetting > 0 ? 1 : 0), false) changed to send(dimmerMsg.set(dimmerSetting));
Now my target is to use the maximum quantity of PWM pins in Arduino MEGA (in total I need 16 so I think I am gonna need two Arduinos)
Anyway could You help me please to add extra LEDs into this sketch ?

So I have right now 6 LEDs in Domoticz connected to Arduino Mega 3,5,6,9,10,11 pins ( I hope all of them are PWM)
At first usage It behaves crazy - It's like every switch needs the first on and off sequence to start behave normally.
What happens then:
LED 1 ,2, 3, 5 - all work ok , every single one saves the last state when switch off/on , dimmer bar works fine
now the best part 
LED 4 - when I switch it On (mouse click in Domoticz) LED is going ON (physically) but the same time LED 1,2,3 is going ON (but only in Domoticz so let's say they are virtually ON but in reality OFF) - dimmer bar LED 4 works ok , saves the last status, You can switch it off but 1,2,3 will be still ON (you have to click each one to take off the virtual status)
LED 6 - works very similar to 1,2,3,5 - when I move the dimmer bar to e.g. 15% LED it is reacting it is ok BUT suddenly after 1-2 seconds dimmer bar goes to full range (led still shines 15%)
LED 6 Is also unique - if I play with any of the switches and dimmer (1,2,3,4,5) this one is going virtually ON (domoticz reporting it is on - and its bar is going to full range)
Please help me to understand where is this behavior coming from.
Honestly I am not a programmer I am not even sure If the sketch which I combined is anyhow feasible.
I had to add some messages so I added everywhere after Your dimmerSetting a line.. message.sensor - but I have no idea what it does. Not sure if it should be message.sensor or something else.
fadeToLevel( dimmerSetting, message.sensor )
and this
fadeToLevel( 0, message.sensor )
and this
fadeToLevel( dimmerSetting, message.sensor
I am thinking maybe I can sacrifice "save the last dimmer value" - just to get this leds working normal
Help Anybody !
P.S
I can paste my debug but there is so many problems I dont even know which bahavior case ( LED 4 or LED 6 or LED1 etc..) I should paste from my debug
@Boots33
Thank You
I've uploaded Your sketch. I don't know why but LED went from 0 to 100% six times in a row, then it stayed on.
When I opened serial monitor in Arduino - it did the same (six times 0-100%) and my debug stopped on the line:
2202 TSF:MSG:READ,0-0-153,s=0,c=2,t=3,pt=0,l=3,sg=0:666
8909 TSF:MSG:SEND,153-153-0-0,s=0,c=1,t=2,pt=2,l=2,sg=0,ft=0,st=OK:1
(666 interesting 
)
Then from Domoticz
Status of the switch was OFF but LED was actually physically ON - so I moved the bar to 33% and it did again (six times but this time from 100% to 33% and stayed on 33%)
After that It started to behave normally when I moved the bar to 56% and to 9%
So basically It works but every initial start whatever it is (uploading sketch, serial monitor, switch on from domoticz) it is doing 6 times complete range
Any Idea why it is doing that ?
Right now I'm planning to extend it to few more led stripes but this will be next step.

Hi
I'm testing Dimmable LED Actuator --> https://www.mysensors.org/build/dimmer
Everything seems to work with Domoticz except one thing - It doesn't remember last dimming value (This is a feature I really need).
After switching the light off and back on , no matter what value was before it goes everytime to 100%
Figured out If I change the value 100 : 1 to 10 : 1 - It goes to 10% - but still It doesnt remember the last dimming value.
// Adjust incoming level if this is a V_LIGHT variable update [0 == off, 1 == on]
requestedLevel *= ( message.type == V_LIGHT ? 100 : 1 );```
I've found a sketch DimmableLight in My sensors examples which I would like to test unfortunately I cannot force it to work with LED stripe connected according to dimmer sketch( Mosfet , led pin 3 etc..)
Could someone help me please with the code ?
Which part is responsible for sending the information to LED_PIN 3 ? I tried to define LED pin3, also fade delay etc... to the below sketch - no luck.
Does it matter if the variables are V_LIGHT and V_DIMMER if the type is S_DIMMER ? (both sketches) Shouldn't it be V_STATUS and V_PERCENTAGE ?
Any help very welcome !
Thanks in advance.

Hello
I need some help !
I've ordered few IRLZ44N Mosfets to play with Dimmable LED Actuator project.
Adafruit RGB LED stripe uses IRLB8721
Could You please tell me if I could use mentioned IRLZ instead of IRLB in case of described RGB project ?
Thank You in advance.
Could You please explain what do You mean by "Change that line in the getID() function to return 0;"
I am trying to run the sketch but I have the same problem as @Aron-Sjöberg.
Could You let me know which MFC library version I should use ?
Thank You. Works perfect and reporting to Domoticz/Imperi Home.
Yes, standard on/off switch
Hello
I'm using modified my-sensors sketch to control few relays. Arduino is connected via usb cable with Domoticz.
Everything works fine but the sketch is designed for monostable switch (doorbell type)
Point is I would like to use standard (bistable) switch instead of (monostable) doorbell switch.
Could You please help me with modifying the sketch ?!?
Thank You in advance.

Thank You gohan
Commenting MY_DEBUG solved the problem.
Could You explain please what this function does ? should I always comment it/ delete ? or there are some reasons for using that ?
Thanks in advance.
