In my case i didn’t get any noise i have use 15 meter long wire you can use high quality cat6 wire which is outdoor rated. Or you can add a capacitor on power line of relay to filter out noise. Use external power supply for relay. And another separate supply for arduino. Check your arduino if it is working properly or try replacing your arduino.

I haven’t tried it with xlights so I don’t know if this will work with it or not.

Its already opened anyone can view it.

Some sensors or led won’t work with long wires due to voltage drop or fluctuations they are very sensitive to them. You can try to put a capacitor on power supply wires.

Help me brother

I didn’t understand what you’re trying to say can you elaborate it more.

I am using an old laptop with Pentium dual core processor 4 gigs ram, 128gb ssd - works smooth

Are going to implement esphome setup. In that case ESP devices are pretty reliable as soon as you configure them in a right way. Esp8266 had 8 GPIO pins but you cant use all of them there is a datasheet which tells you which pin you can use. If by mistake you used the wrong pin the whole device crashes and does not come online. I am using this setup for almost 10 months now. And it is pretty reliable as soon as I do not configure it wrong.

well the problem seems to be different, it seems like relays problem, when i was connected in the relay K1, I connected power on NO/NC thing of K1 the click sound got low (still clicking) but power was not stoping on switching (meaning device connected to relay still remains on), now when I shifted it to K7 relay same thing is happening again again K1 seems to be permanently damaged (low click sound, always remains on). For context I was trying to power my monitor using this relay which looks similar to yours. Is it something to with relay ?

If you have multiple arduinos each arduino will have its own COM port just name it differently in vixen for example: if you have two arduinos one controlling house front and second grass name them house front controller and grass controller. And if you want pixels on each arduino pin that is not possible because arduino have very less memory to barely controll 300 pixels.

I have used 5v relay you can use whatever you want. But give relay external power do not power them using arduino on board power supply.

I am unable to understand what you are trying to say and google translator does not helped much. If you can speak english please let me know.

Yes you need to make some changes to the code.
