@aivaredze Great project. Absolutely great video! Love it. One question: how did you manage to hide the cables between your shield and the led strips? Maybe some pictures?

Great video!!!!

@mar.conte A shot in the dark but have you tried to pull down pin 3 in order to prevent this pin is floating? Connect pin 3 to ground with a 10K resistor.

@mar-conte
What happens if you change your sleep function like this:

sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), HIGH,0);

Domoticz > Settings > uncheck "Accept new Hardware Devices". Don't forget to click Apply Settings.

I think the sketch you need is here .

@tekka Yes! This works. Thanks for your help. I'm still confused why my test script worked with 2.0.0. and not with 2.1.1. Thanks again.

@Yveaux I'm using my own pcb's. Nothing special. It has the ATMEGA328p (8 Mhz) and the nrf radio. The hardware worked with MyS library 2.0.0. Using Arduino 1.8.1. Board UNO 8 Mhz 3.3v.

After upgrading the MySensors library from 2.0.0 to 2.1.1 I noticed that the sleep function with interrupts was working different than before. Have a look at the simple test sketch below . In 2.0.0 the loop is called only once after an interrupt. In 2.1.1 the loop is called twice before the sleep function becomes active. Below you have the serial log for 2.0.0 and 2.1.1. for 2 interrupts. Is this a bug or do I need to change some settings or use a different code?

//Test sleep function and interrupt in library 2.1.1 and 2.0.0

#define MY_DEBUG 

#include <SPI.h>
#define MY_RADIO_NRF24
#include <MySensors.h>
byte countInterrupt;
void isr() {}
                                                                                  
void setup(void) {
  pinMode(3, INPUT_PULLUP); // intterupt 1
  attachInterrupt(digitalPinToInterrupt(3), isr,FALLING); 
}

void loop() {
  sleep(1,FALLING,0);
  Serial.print("interrupt ");
  Serial.println(countInterrupt++);
  wait(1000);
}

Serial log 2.0.0 (this one works ok).

@gohan Maybe this one?

@RaPo You can zip your .brd and .sch files and upload the zip file.

@Raghavendra-Prasad Looks like interference between the radio module and and the pcb. Could also be a GROUND problem with your pcb (it works when you're touching the antenna).

First: remove the nrf from your pcb and reconnect with some jumper wires. Make sure the radio module is outside the pcb. If it works you have to redesign your pcb in such a way that the antenna is outside the pcb.

You could also try to shield your nrf (search the forum).

If it's still not working could you post your EAGLE files? (board and circuit file).

Success

@lozzer65 I'm very curious where you bought the radio with the proper IC and components!

I have used seeedstudio.com for PCB's and laser cutting. They also do 3D printing. No complaints so far.

@mfalkvidd
When you open YouTube itself then look at the uppper right corner where you should see 3 dots. Tapping these dots will give you the all available options.

@mfalkvidd
In Youtube you have an option to enable/disable Youtube links to open in Chrome.

@mfalkvidd
Use Chrome on your iPad and your problem is solved!

@Lee-Groom

Have a look at MyConfig.h. If you have "#define WITH_LEDS_BLINKING" then D4, D5 and D6 are used for blinking the status led's. Could maybe explain your problem.

@sundberg84 , @jlehtinen

I've solved this problem with a LUA script in Domoticz. The script copies the values of temperature and humidity to a TEXT sensor (as a string). In the Arduino sketch (you need the MySensors development branch) the string is split in 2 separate values (Strings). Works like a charm.

LUA script:

   tempString = ""
   stringReturn = ""
   sensor = '103OutsideTempHum'
   tempString = otherdevices_svalues[sensor]

   sep = ";"
   i=1

   for str in string.gmatch(tempString, "([^"..sep.."]+)") do
      stringReturn = stringReturn .. str .. "#"
      i = i + 1
   end

commandArray = {}

   time = os.date("*t")
   if ((time.min % 5)==0) then--run script every 5 minutes
   commandArray[1] = {['UpdateDevice'] = 77 .. '|0|' .. tostring(stringReturn)} -- 77 = idx of TEXT sensor in Domoticz
   end

return commandArray
