@AWI Thanx for the advice! i will try it as soon as i get the chance. Great work!! thanx.
@Cliff-Karlsson Afaik, the numPixels correspond to the total number of leds combined with up/down or left/right. So 16 will make it an 8x8 wall light and 2 would make it a 1 by 1, 72 would make it 36x36. As far as the triggers in Domoticz, i am also new at this. I did manage to get the alarm running and the patterns through the dimmer function, but am unable to set up the patterns on a switch. Domoticz won't let me somehow. Will try to give this more prio.
Keep trying! and posting please

Hey @AWI
I have some trouble using this with MqTT messages.
I can get alarm to go off by sending a payload of '1' to 'InMQTT/62/4/1/0/2' and subsequently turn it off with any other value.But I can't get the rest of your functions to work!
If I read your code correct, to set a solid color I would have to send several MqTT messages to the children?
Ex, I would have to send 'InMQTT/62/1/1/0/40' and payload ex 'Candle' first.
Then 'InMQTT/62/1/1/0/2' with payload of '1' to turn it on?
I was looking at the serial protocol and do not find what V_Dimmer is for type. (https://www.mysensors.org/download/serial_api_20#variable-types)Anyways, i cant get it to work properly, maybe you could shed some light (pun not intended :+1: ) )?

If someone still needs it, I managed to control it via mqtt (node-red). I am about to integrate it into the openhab, it might be easier to start that but I wanted to have good control over it (and understand mqtt a bit better).
In sketch I had to change} else if (message.type == V_DIMMER) { // if DIMMER type, adjust brightnessto V_PERCENTAGE for latest api/mqtt
and I am still struggling a bit to turn all LEDs off completely. Only way I could achieve this was to set color to black (000000). code as it is always leaves my LEDs to 1% or something. But that might be due to node-red implementation, as I do not have response from node-red on "questions" from the node (at some point in code node will ask controller about some values (color if I remember correctly), but I just send the color and brightness manually via injectors). I guess this can be fixed on the controller side, and most likely works with openhab implementation.
Here are the triggers in node-red
Here is the node-red code

Hello all, many thanks to @AWI for this great sketch - it performs very well and is my 'go to' for a WS28XX interface with Mysensors and Openhab.
I am however, starting to experience problems introduced with the FastLED 'wait' commands and the radio receiving a command - essentially, if I command the node to a pattern that is particularly blocking - I cant them command it to off, solid colour or another pattern.
Anyone solved this problem - or able to point me in the direction of solving. I'd be happy to refresh the sketch and re-share.

Morning all, apologies for waking up an old thread, but it's pertinent to this chain of thought:
I'd like to build on this code and introduce a few more LED settings according to the percentage figure sent in the RGB dimmer.
Can anyone explain which part looks at the percentage and translates it out to the pattern?
How would I go about adding a new pattern to a chosen percentage value?Many thanks

Hi @adds666 . I think it is this bit in the receive() function near the bottom of the code. It gets the value from the V_PERCENTAGE message and maps into the setPattern value:
case RGB_NextPatternChild: // next pattern if (message.type == V_PERCENTAGE) { // Percentage indicates the pattern setPattern = map(message.getInt(), 0, 100, 0, 15) % lastPatternIdx ; // mapper dimmer value to state 0..9 and wrap setLightPattern((setPattern), 500 ); Sprint("Pattern: ") ; Sprintln(setPattern) ; } else if (message.type == V_STATUS){ // if off switch pattern to default == 0 setPattern = 0 ; setLightPattern((setPattern), 500 ); Sprint("Pattern: ") ; Sprintln(setPattern) ; } break ; -
Hi @nagelc , thanks for coming back to me - Apologies I didn't realise you'd replied nearer the time.
Am I right in thinking, so long as I define the new patterns function later on in the sketch - I can include it in the switch of function updateLightPattern, and it will be added to the mapping?
How do we know what definitive figures the 0 to 100 percentage map to in 0 to 15? Or is that basic arithmetic and each switch state will be called in each 'chunk'. I also only count 10 items in the switch state. Does that mean we can add 5 more? and if wanting more than 15 simply change our mapping size to have more?
Appreciate the help.
void updateLightPattern(){ // global: curPattern, updatePatternDelay, lastPatternUpdate unsigned long now = millis() ; if (now > lastPatternUpdate + updatePatternDelay){ // check if time for update switch (curPattern) { case pAlarm: // flash light patternAlarm(); break ; case pFire: // wild fire patternFire(); break ; case pFire2: // cosy fire patternFire2(); break ; case pCandle: // flame patternCandle(); break ; case pCircle: // flame patternCircle(); break ; case pRainbow: // rotating rainbow patternRainbow(); break ; case pSinelon: // rotating rainbow patternSinelon(); break ; case pSolid: // do nothing fall through case pOff: case pOn: default : // def break ; } lastPatternUpdate = now ; } } -

It'd about 10 steps. That's why I'm not sure if you can add more patterns. Unless you indeed change it to a percentage. Hope it helps
