@iamtheghost have you checked this: https://www.mysensors.org/controller
What about this
http://mycontroller.org/

@strangeoptics I've created a simple python file just to connect to an ethernet MySensors gateway and monitor all output:
https://github.com/dirkclemens/myssniffer.py/blob/master/myssniffer.py
If you want to use it with a serial gateway you have to make some changes in the main() routine to grab data from the usb port instead the ethernet port.

@ZenBlizzard , yes thanks, thats the point. How to deal with smartSleep() and battery lifetime.

Hi all,
has anyone yet implemented some kind of multi tap button with MySensors?
Such as single-click, double-click, long-press, ... ?

I think, I cannot work with interrupts, as I can get a HIGH/LOW once only and cannot count for long-press? Correct? And a battery mode node cannot be used either (with smartSleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR_2),...) because I have to check for e.g. a long-press which might last some seconds ...

Thanks in advance for any comment or code example?

@terence-faul any solution so far?

I found this:

create a file, e.g. mysensors_bootloader_130_8Mhz.json and save it to ~/.platformio/boards/

{
  "build": {
    "core": "arduino",
    "extra_flags": "-DARDUINO_ARCH_AVR -DARDUINO_AVR_PRO",
    "f_cpu": "8000000L",
    "mcu": "atmega328p",
    "variant": "standard"
  },
  "frameworks": [
    "arduino"
  ],
  "fuses": {
    "efuse": "0xFE",
    "hfuse": "0xD2",
    "lfuse": "0xE2",
    "lock": "0x0F",
    "unlock": "0x3F"
  },
  "name": "MySensorsBootloader 1.3.0 (Atmega328P@8M,3.3V)",
  "upload": {
    "maximum_ram_size": 2048,
    "maximum_size": 30720,
    "protocol": "arduino",
    "require_upload_port": true,
    "speed": 57600
  },
  "url": "http://www.mysensors.org",
  "vendor": "MySensors"
}

the platformio.ini should look like this:

[env:mysensors_bootloader_130_8Mhz]
platform = atmelavr
framework = arduino
board = MYSBootloader_8MHz.hex
src_build_flags = -I/Users/dirk/Arduino/libraries/MySensors

lib_deps =
  # Using a library name

but I do not know where to store the MYSBootloader_8MHz.hex

@mfalkvidd said in Atmega328 internal temperature sensor (yes it exists!):

hwCPUTemperature()

sorry, stupid question maybe, but with my 328p based sensors hwCPUTemperature() is not automatically callable using just
#include <MySensors.h> --> neither with 2.2.0 nor with 2.3.0

Do I have to include /hal/architecture/AVR/MyHwAVR.h ?
Cannot compile it, what path should I use in the #include statement?

@terxw all files from https://www.openhardware.io/view/562/simple-MySensors-MultiSensor-Board were sufficient, when I ordered my boards at allpcb. But you can create them with eagle on your own.

I always suggest to use caps wherever you power the board, because it "levels" or "balances" the current so it has more "stability". The resistor connected to reset is always needed as "pull-up", without that, the processor will either reboot or be unstable.

@thucar what display do you use and where did you buy it? What library did you use?

@ostoja look at this video with an explanation of this topic and how to handle the IDs
https://forum.mysensors.org/post/26597

@ostoja said in Multiple Relays + Motion sketch, fully customizable, optional timer, manual override:

// Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }

  // Register all sensors to gw (they will be created as child devices)
  for (int sensor = 1; sensor <= NUMBER_OF_RELAYS; sensor++) {
    present(sensor, S_BINARY, "Relay", ack);
  }

With this two "for" loops you set present(n) multiple times. in the first for() you start with 0 until MAX_ATTACHED_DS18B20-1, in the second for() you start with 1 until NUMBER_OF_RELAYS-1, so this will assign the sensors with identical IDs as the relays.
I have not checked the internal code of this method, but I would think that you should better user a different range in the second for() loop starting at least with MAX_ATTACHED_DS18B20+1.

Thanks, @tekka, but unfortunately I am still using the wrong code. I tried every combination, but as I am not sure what am doing here, I doubt to make progress.

set MOSI,SCLK,CE,CSN to OUTPUT -> SPI_DDR = _BV(SPI_MOSI) | _BV(SPI_SCLK) | _BV(CE_PIN) | _BV(CSN_PIN)
set PB2 to OUTPUT -> | _BV(PB2)
set MISO to INPUT -> | ~_BV(SPI_MISO)
and set CSN to output -> CSN_DDR = _BV(CSN_PIN);

The controller still doesn't recognize the node, so I cannot use OTA. But when I flash the sketch (with the CE and CSN pin defined to 8 and 9) with a programmer to an atmega328p with a standard bootloader it works, so my PCB seems ok.

#elif defined(SPI_PINS_CSN9_CE8)
	// set pin mode: MOSI,SCLK,CE,CSN = OUTPUT, MISO = INPUT
	// PB2 is SS pin has to be defined as OUTPUT, else SPI goes to slave mode
	SPI_DDR = _BV(SPI_MOSI) | _BV(SPI_SCLK) | _BV(CE_PIN)  | _BV(CSN_PIN) | _BV(PB2) | ~_BV(SPI_MISO);
	// set CSN = output
	CSN_DDR = _BV(CSN_PIN);
#endif

Looking to other bootloaders was no success, e.g. optiboot.

Thanks in advance for any hint or better some sample code.
