hi, i used the example sketch. i also changed from "delay" to "wait" in fade section. The problem: i can change the percentage for example 8 times and then the gateway crashes and reboots. In a other case it works 12 times and then the gateway crashes. All other nodes (Temp, Hum) works fine all the time.

Problem solved! The 3.3v Form arduino nano was too Bad for the nrf24l01j pa lna with PA_LEVEL MAX. NOW i usw an external regulator an everything is fine :-) sorry for this newbie fault :-D

Hi, I've noticed the V_DIMMER of the example is not (anymore?) available in https://www.mysensors.org/download/serial_api_20, am I wrong? Thanks

Dear Guys,
How can I control an RGB ledstrip with this config may I add more MOSFAT or how ?
Thank you very much.L

so this works now like a charm:
// Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 //#define MY_RADIO_RFM69 #define MY_NODE_ID 153 #include <SPI.h> #include <MySensors.h> #define SN "MultiDimmableLED" #define SV "1.1" #define noLEDs 3 const int LED_Pin[] = {3, 5, 6}; #define FADE_DELAY 25 // Delay in ms for each percentage fade up/down (10ms = 1s full-range dim) static int currentLevel = 0; // Current dim level... MyMessage dimmerMsg(noLEDs, V_DIMMER); MyMessage lightMsg(noLEDs, V_LIGHT); /*** * Dimmable LED initialization method */ void setup() { // not sure this works // 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 ); } } void presentation() { // Register the LED Dimmable Light with the gateway for (int sensor=1; sensor<=noLEDs; sensor++){ present(sensor, S_DIMMER); wait(2); } sendSketchInfo(SN, SV); } /*** * Dimmable LED main processing loop */ void loop() { } void receive(const MyMessage &message) { if (message.type == V_LIGHT || message.type == V_DIMMER) { // Retrieve the power or dim level from the incoming request message int requestedLevel = atoi( message.data ); // Adjust incoming level if this is a V_LIGHT variable update [0 == off, 1 == on] requestedLevel *= ( message.type == V_LIGHT ? 100 : 1 ); // Clip incoming level to valid range of 0 to 100 requestedLevel = requestedLevel > 100 ? 100 : requestedLevel; requestedLevel = requestedLevel < 0 ? 0 : requestedLevel; Serial.print( "Changing LED " ); Serial.print(message.sensor); Serial.print(", PIN " ); Serial.print( LED_Pin[message.sensor] ); Serial.print(" level to " ); Serial.print( requestedLevel ); Serial.print( ", from " ); Serial.println( currentLevel ); fadeToLevel( requestedLevel, message.sensor ); // Inform the gateway of the current DimmableLED's SwitchPower1 and LoadLevelStatus value... send(lightMsg.set(currentLevel > 0 ? 1 : 0)); // hek comment: Is this really nessesary? send( dimmerMsg.set(currentLevel) ); } } /*** * This method provides a graceful fade up/down effect */ void fadeToLevel( int toLevel, int ledid ) { int delta = ( toLevel - currentLevel ) < 0 ? -1 : 1; while ( currentLevel != toLevel ) { currentLevel += delta; analogWrite(LED_Pin[ledid-1], (int)(currentLevel / 100. * 255) ); wait( FADE_DELAY ); } }``` thank you :thumbsup: -
Ah I have just built a test bed with this setup however it appears the circuit diagram in the Fritizing is actually not 100% correct. The red wire from the protoboard is connected to the GND of the Pro Mini - this confused me as I was using the GND/RAW pins to identify the cable color. If you flip the red/blue connections on the Pro Mini it will be right. Small issue I know but I had to reference another image to get the circuit to work.

Hi Folks,
I have build this in combination with a ethernet gateway. Works perfect, however, when for whatever reason the network fails, I cannot control my lights anymore.
Is there a possibilty toi have it working also "stand alone" when the network fails?
Grtz.

Hi all!
I'm using OpenHAB 2, and I have some problems with the sketch code "DimmableLightWithRotaryEncoderButton".
- When the encoder button is pressed, the switch in OpenHAB does not respond.
- When you turn the encoder knob one step, the value changes in two steps.
Maybe you have encountered such a problem? Or maybe you can share a more modern sketch?

Does anyone use this sketch "DimmableLightWithRotaryEncoderButton"? I take it from the site (https://www.mysensors.org/build/dimmer) and it does not work with OpenHAB 2.

does anyone have working sketch -> DimmableLightWithRotaryEncoderButton.ino with Mysensor USB under DOMOTICZ + Arduino ? unfortunatelly phisical button dosn't work (no switch on / off) and there is no feedbeck from domoticz to Arduino to set level of dim. I have been straggling with the sketch for weeks, but haven't figured out , how to fix it. Mybe something has changed since lat update od sketch... and sorry for my english I'm not a native speaker:)

@hard-shovel I've already used this sketch, but still no feedback from domoticz to arduino (it does not dim) and the physical button doesn't work :( ehh...

Attached is a sketch that i have just tried with domoticz (running on a windows test machine) It works fine when used as a node with a gateway. Encoder/ Switch and webpage slider/switch operating.However when set up as a single gateway node as your sketch, only the encoder function works, you can vary the lamp level from the slider or the encoder, but the domaticz on/off or the button does not operate correctly. it seems to be the way the messages are acknowledged
I also find that when i change the led dimmer from the encoder the led changes quickly, but it take about ten seconds before the dormoticz web page updates to show each new slider position.
The following Sketch needs the #define OPENHAB2 defined for use with openhab and undefined for Dormoticz

@hard-shovel thanks a lot for you post and effort to test it!, I've tested also the version of sketch without rotary encoder and this one works fine.
