💬 Dimmable LED Actuator
-
It's a closet with two sliding doors and therefore two magnetic switches, and I want the LED to turn on when opening one of the doors, but also be able to turn it off remotely if we forgot to close it when leaving our home.

I would like to use this with a 48 Watt led which uses a constant-current power supply 54 - 87 VDC 600 ma output. This mosfet isn't high enough voltage rating, the IRF630MFP is rated at 200V 9amp, however I have questions about if the uC output will power the gate. The gate-source voltage is +/- 20. The VGS(th) gate threshold voltage is 2 to 4 volts with typ 3V. I would cut the negative from the power supply and connect to source, then connect the Led negative to drain, and connect the drain to ground on the uC? I need a reality check- does this sound possible or will I fry something?

Hi,
I'm new in MySensors and build this Dimmer - LED with and without the rotary encoder which works fine.
Now I would like to decouple the rotary encoder as a battery powered "standalone" sensor which is (in best case) connected directly to the LED-Dimmer. Furthermore the decoupled rotary encoder should be always in sleep mode until the rotary encoder awake the arduino.
Is that possible ? I'm just stuck to seperate the code for the rotary encoder from the led-dimmer code.
Thank you in advance. -
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:)
