You are right. Mysensors based on NRF is dead. I started my adventure with home automation based on mysensors but gradually I replaced all my sensor with Wemos. Now everything work fine. Sorry mysensors...

After 3 years of using RADIO_RF24 i replaced my all sensors with espeasy. It was just big battle with lost transmissions, disconnections, every day problems. Now for many days silence...Everything works.I still use mysensors in diferrent setup but NRF Radio is asking for trouble.

Hi,
Here is a sketch for multi buttons (no relays, no repeated parts of code for each buttons) just enter number of buttons and first digital pin where buttons are attached.
Thanks to @hek for help...

/**
   The MySensors Arduino library handles the wireless radio link and protocol
   between your home built sensors/actuators and HA controller of choice.
   The sensors forms a self healing radio network with optional repeaters. Each
   repeater and gateway builds a routing tables in EEPROM which keeps track of the
   network topology allowing messages to be routed to nodes.

@hek said in 💬 Door, Window and Push-button Sensor:

pinMode(i + FIRST_PIN, INPUT_PULLUP);

Big Thanks!
I have changed all array parts in setup in the same manner like above and it works :-)

@hek
I have changed

pinMode(buttonPin[i + FIRST_PIN], INPUT_PULLUP);

to

pinMode(buttonPin[i + FIRST_PIN], INPUT);

thanks, but sadlly still does not work...

@hek
That part was in original sketch for establish internal pullup as I understand. I used array to do it for each pins.

@mfalkvidd
thank you, i hope will be good soul who fix my sketch itself to work... :-)

Hi,
I rewrite sketch for doors/window/buttons to work with multiple buttons (no rellays) .It shows up in Domoticz but it did not change status buttons if pressed.
Can someone look for the skech what I am doing wrong

@palande-vaibhav
Sorry for the dumb question. How do you achieved different #numbering in Values? I have all my Ds18b20 sensors with #1 number.
