hello,
I just deleted the eeprom but I still have the problem.

hello,
I have problems with my 1-wire node, so I used two buses (pin2 and pin3).
all my temperatures are visible but some have the same id.

*******************************
*
* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on serial which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or receive crc error

for me the first 2 lines and the last two are different probes but with the same id.
how can I have a single id ?
thanks

I am using domoticz and I would need a virtual switch to change a time base in mysensors
I have the virtual switch in domoticz but whether or not I activate the switch, the time base never changes .
I have another question: is it possible to send a pressure in bars and not in hpa ?
thanks
