💬 Door, Window and Push-button Sensor

  • My sketch have 2 binary switches. Working very good.

  • what is "debouncer" for? I removed it from my sketch and it still works...

  • Mod

    @siod when a switch is pressed it can bounce, which can look like several presses to the mcu. More information is available at http://www.allaboutcircuits.com/textbook/digital/chpt-4/contact-bounce/

  • Hardware Contributor

    I did just build a similar sensor based on my small sensor node. I think the example code here isn't really perfect though (although its very basic, perhaps that was the only goal).

    As I wanted to use this with batteries I used an interrupt and sleep(). The deboucing library isn't really need, a short gw.wait(50); did it for me too.
    Here is my code (not yet updated to mysensors 2). Any comments? Perhaps we could update the example code too.

  • Dont forget to add a 10K resistor between GND and your PIN (in this example pin3)

  • Hardware Contributor

    @janvier123 Do you really need that? Shouldn't the internal pullups be enough?

    // Activate internal pull-up

  • for some reason the value was always "1" untill i "pushed the button" => then i got "0"
    however ive added an 10K resistors between the pin and gnd, and now it works fine 🙂

    maybe because its not an official UNO board?

  • i don't why, but debouncer.read(); always return 1, i was never able to send the status of the door, however, digitalRead(BUTTON_PIN) returns the actual value.

    since i am using this for reed switch, i believe i don't need the debouncing functionality do i ?

    yes you can get rid of the debouncing stuff for your reed switch (or any physical switch) if you are sleeping and waking up on interrupt, just add a little wait before you read the value to let the switch settle.
    If you are running at 1MHz then the time to wake up from sleep is longer (45ms if I remember well) and you don't even need the sleep.

  • What is the way to put the sketch on a sensebender with battery powered ?

  • Is the BinarySwitchSleepSensor a good answer ?

  • @Meshx86

    I have the same problem, when I use the bounce library to read my reed switch I always read "1". If I use digitalRead I get an bounce error.
    I have an arduino compatible, configure it for 1Mhz, 1M resistor for the reed switch and 2 AA battery.
    Someone has a similar one working?

  • @Jic i was wondering what's the purpose of the 1 M resistor on the reed switch ?
    i used 2 x AA battery, digitalRead, 8 MHz stock clock and no resistor, i know this might not be the most optimized power consumption setup

  • Nuub here..
    Thinking about building this in my mailbox..
    AND if possible set a green light diode to start light when box is opened and stop when its opened again.

    That way i would see when i come home if someone has opened the mailbox or not.. Sure push notifications work aswell but it would be a nice touch for the wifey

  • Hardware Contributor

    @meanmrgreen if you use a led it will draw a few mA when on and battery life will be poor.
    At best you could wake up every few seconds and flash it briefly (like 100ms or less). In that case use a low value current limiting resistor to have an intense flash, and probably a red LED is better.
    To stop the blinking why not use a button (or touch button, check TTP223 in AliExpress) inside the mailbox ?

  • Mod

    Not sure if it more battery friendly, but maybe sending a bluetooth low energy beacon is better than a led? Higher nerd factor for sure, but maybe less spouse friendly (depending on how good the ble app on the phone is).

    Seems like it would be possible by using an extra nrf24: https://github.com/floe/BTLE/blob/master/examples/send/send.ino

    On the other hand, if a smartphone is required you might as well open the app for your controller and check the status there 🙂

    Maybe use a battery-friendly PIR and only light/blink the led when motion is detected?

  • You lost me at bluetooth beacon? 🙂

    Me personally is using the app but wifey and kids ain't really as interested as i am 😉

    So therefore I would need a indicator of some sorts around the mailbox that is about 30 meters from the house in the road up to the house.

    Maybe a solar led light or similar to light up? Or a flag on a servo?

    Will start with building the switch and figure out the indicator later.

  • Hi Everyone
    Be carefull a newby here... 🙂

    I have ordered all the parts for my sensor network. My plan is to have battery powered sensor sensing the following: Door/window status AND temp/humidity. Doing all this in a low power fashion.

    My question is: Would these code in the build section be easily combined (dooe switch and temp/hum) in a way that it measures the temp/hum regurarly (every 15-30 min) and if during the sleep a door event happens it sends the door event to the gateway (and probably since we are awake do a temp/hum measurement as well)?

    Every piece of direction, advice is appreciated.


  • Like I said..newby here. Hold back your horses for a moment, I did a deep search and found some interesting forum topics here 🙂

  • Mod

    @Atesz very welcome to the MySensors community!
    "easily" is in the eye of the beholder, but I'd say yes. https://forum.mysensors.org/topic/2597/combining-mysensors-examples is a great starting poing for combining sketches.

  • @mfalkvidd Thank you very much, it is almost what I've been looking for !

  • Goodevening,
    I am new to mysensors (newby) i wil make 3 sensors on my mini pro can some one help me with the sketch.
    I am working a hole day but i can't get it writh help is very use vol.
    One switch (reed contact) is working.

  • Admin

    Hi Ton,

    You have to give us a little bit more information here (and please start a new thread for your project).

    Normally good to give information about:

    1. What are you trying to accomplish?
    2. What is working?
    3. What is not working?
    4. What did you try yourself before posting?
    5. What is the expected result?
    6. Logs from the sensor/gateway/controller.

  • I had big problems getting this one to work in Domoticz... But then I downgraded the Arduino IDE to IDE 1.6.7 (https://forum.mysensors.org/topic/5164/ethernet-gw-w5100-can-not-connect-to-domoticz/2) and then it worked!

  • @hek,

    Thanks for the reply.

    What are you trying to accomplish?
    I want to try 3 reed/door contacts on one mini-pro on pin 3,4 and 5

    What is working?
    One reed/door contact is working

    What is not working?
    I don't no how i must make a second reed/door contact in the sketch (door/window push button)
    I am new to programming arduino and don't undertsand how to do that, ik look for a hint how i can implement a second reed/door switch in the sketch

    What did you try yourself before posting?
    I look many sketches on internet and try to copy a copple of line in the working sketch but i don't get a second reed/switch in domoticz. I am trying this a hole day (i am with pension).

    What is the expected result? a second, thirth reed/sensor in domoticz i see here only the first sensor.

    Logs from the sensor/gateway/controller.
    The log for the first reed/door switch i see and it is working in domoticz, that is not the problem.

    Sorry for the bad English.

  • @ Svante

    Thanks for the reply but is is working well with one reed switch. So that is not the problem I want on the mini/pro a second and thirt switch.

  • Hi, New here but stumbled across this.
    I am planning on re-using an old wired alarm system that has door and window sensors all over my house terminating under my stairs. Can I combine one sketch into multiple door reed switches on one arduino. That seems to have been asked before but there doesn't seem to be an answer. It would be quite annoying to have 8 arduinos next to each other in order to do so.

  • Hardware Contributor

    @nickgosling - no problem if you have 1 wire for each reedswitch you could just add it to different input/pins and have 1 arduno check which pins is high or low.

  • Thanks for the response. OK I'm fine with assigning a pin as an input but how would I change the code to reflect this .thanks.

  • Hardware Contributor

    @nickgosling - take the sketch and add one child for each sensor. Define one input for each sensor and in the loop check each pin for a statechange. With a if you can then send the status for each changed pin.

  • Thank you I'll give that a go.

  • Hi,
    Maybe it is a little off-topic here, but maybe you could point me to the right direction: I want to build nice wall switch, and from technological point of view it is not that difficult using mysensors, this part is clear, including battery powering or making some kind of power conversion from AC to DC (in openhardware there are quite a few examples on that). What is bothering me is the switch "enclosure". I have one example from TKB Home:
    that I have bought to try with smarttnings controller (which is not intended to work with, now I know), but what it has - it is the enclosure: it is nice switch with 2 micro switches inside (4 in total, since it is dual wall switch), that are not locking in the pressed position - you press up and it clicks one button/switch and returns back to its initial "neutral" position, you press down - again, click and back to "neutral".
    I think the similar are are in aliexpress, that are called like wall wireless remote switch Transmitter, but I'm not sure about that, since I didn't bought one to disassemble.
    Maybe some one have met something similar for making some nice RF controlled wall switches?

    Thanks in advance!

  • Hardware Contributor

    @Justas Hello, please check the dedicated category, if you don't find your hapiness please post there 🙂


  • I tried this today and it wouldn't find a parent.

    Adding #define MY_NODE_ID 1 seems to have solved the problem, so maybe this (and other) examples need to be updated with this info?

    Thanks for the work on this project though, I think it will be a lort of fun when I get it all working! 🙂

  • Mod

    @skywatch that shouldn't bee needed. Would it be possible for you to post the entire log from when the node was unable to find parent?

  • I'll see if I can replicate it ...been nusy trying to sork out a controller now Heheh.....Not fun!

  • I just uploaded the sketch again without the define and it is working - I didn't clear the eeprom before uploading so maybe that would have made a difference? Is there a list of what is held in eeprom anywhere?

  • Hi instead of using a arduino nano can i use esp8266 for a sensor

  • Mod

    @joseyapor yes you can but the esp8266 has very few usable io pins so connecting a radio and sensor at the same time might be difficult.

  • @joseyapor Yes no problem. 8 digital I/O. One of them a bit problematic as input (used for program mode)

  • Another newbie sorry.
    Trying to use this as a simple doorbell, just to send a trigger to Domoticz.

    I connect doorbell button to digital pin 3, the Node appears in Domoticz ok as a "security sensor" but shows as state "ON". However pressing the button appears to do nothing sadly, switch status stays as on, and log shows no activity at all?

    Using a Uno (clone) and wondering if somethings up with it? 😞

  • Hardware Contributor

    What does the nodes and/or the gateways log say?
    It might not change in domoticz if you just send on but no off signals but it should still be visible in the nodes log (arduino and in domotizc)

  • Hold that thought, embarrassingly it might just be a bad connection! Oops
    Just took it all apart in frustration, had a cuppa and put it back together.
    And something is triggering now, need to play some more, but first hurdle looks like possibly a simply connection maybe.
    I'll let you know.

  • Not sure what I'm doing wrong but I tried to add more than one sensor and didn't get very far. Was hoping to do a motion and a door sensor from the same arduino.

  • As doors and windows are usually not near power sources would it not be better to have this sketch with a SLEEP function and trigger on interupt?

  • what is the logic of the variable "V_TRIPPED"to use? I just messed a little with the MyController application, and by using the V_TRIPPED the value changes from off to on,and stays on,even if the button is released? ( simular to close an opened door)
    Should the variable not be of a binary type with according sensor type?

  • Hi,
    I have my sensor working well, Arduino pro mini with an Ethernet gateway using Home Assistant. .This is the first sensor I'm actually using a battery, so I've never really needed it, I see the battery level in HA as 0, how do I turn that on and use the battery level? Any pointers?

  • Dumb question, but how would I set this sketch to have an array of 5 switches? I’ve tried a couple of things but I’m lost

  • 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

      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.

    I fixed it for you.

  • @mfalkvidd
    thank you, i hope will be good soul who fix my sketch itself to work... 🙂

  • Admin

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

    What is the purpose of the buttonPin-array?


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

    This will fetch a random (probably 0-initialised) value from the array and set pinmode on that value...

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

  • @hek
    I have changed

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


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

    thanks, but sadlly still does not work...

  • Admin

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


    I don't get the buttonPin array thing at all?

    Why not just:
    pinMode(i + FIRST_PIN, INPUT_PULLUP);

  • Mod

    @hek if the array was initialized, it could be used to set arbitrary pins. So pin 4,5,6,7,8,A0,A1,A2,A3 could be used for example (to avoid conflicts with the standard nrf24 wiring but still allow a lot of buttons). But as you mentioned before, without initializing the array the behavior will be strange.

  • @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 🙂

  • @rodaman
    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...

  • Mod

    Could these reed switches be used in the NC configuration for door/window sensor to save more battery?

  • Hardware Contributor

    yes exactly.
    i made a nrf5 board using this principle.

  • Mod

    did you use those with 3 pins?

  • Hardware Contributor

    yes no-nc reed, connect them to IOs of your mcu and switch between input and output

  • Hardware Contributor

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

    did you use those with 3 pins?

    I use them, with one wire connected to each interrupt pin (I only activate the one that's not connected) and they work fine.
    Else you can cheat with a basic reed switch, you just need an additional magnet on the other side of your switch that's weaker than the door magnet, and turn your reed 180°.
    You make the weak magnet close the reed when door is opened and far from the strong door magnet. When you close the door the strong magnet will open the reed switch.

  • Mod

    given the low price, I think it is not worth the extra work to "mod" the normal reed switches 😄

  • Plugin Developer

    I'd like to go even simpler:

    • Window is closed - magnet pulls reed switch so that no power flows to the NRF5.
    • Window is opened - The NRF5 now gets power, boots, connects to the MySensors network, and sends a "window is open" message every 10 minutes.
    • Window is closed again - NRF5 loses power.

    Seems to me that this would be quite energy efficient?

    Perhaps build it into this case:
    (runs on 2 AAA batteries)

  • Hardware Contributor

    I would say this technique is efficient depending on the usecase.
    For example, for basic ambiant sensors not needing any security why not. On other side, for main doors which could benefit security, I prefer to use hearbeat with less interval time, so it's possible to know if the sensor is offline. else controller wouldn't know this if the sensor only update when door state change.

  • Plugin Developer

    Totally true.

    I was wondering what the state of Attiny85 support is. For absolute beginners (in workshops) it might be easier to connect the radio to a digispark.

    // cancel that. It could never support encryption.

  • I have some troubles with this device.
    Sometimes it does not respond to the first click, sometimes it remains switched on after first click until second click

    When I press the button once - I see the LED on my gateway blinks always 3 times
    1 RX TX
    2 RX ERR
    3 RX ERR

    Device powered with CR2032 and running on 1Mhz@1.8V (internal clock)
    Button input pulled to GND with resistor 47K and waking up if VCC connected through the button
    Also have a 10uF tantal capacitor on power supply pins +several 0,1uF ceramic capacitors

    Then it continue works as before

    Actually I have problems only with fu@ing button, most simplest device. Several month I can't to start use it.
    All other devices are working properly even on 2.3.0 ver. 😜

  • Mod

    Have you tried with a debouce? Just in case...

  • This post is deleted!

  • @gohan the default sketch with debounce library works better, but now i see my primary problem.
    Occasionally I have an ACK errors

    I tried to icrease the time ack on my controller - it does not help
    Ithink that I need to ckeck ack state on the node and send the message again, but have no idea how to do

  • Mod

    you are at the limit of the radio range I'd say so randomly it looses a message, so you need to either increase power or get a better antenna (I hope you aren't using any buck/boost converter as power supply)

  • @gohan how you know?
    Id 21 from range 0..255. Are you sure that is limit?

    Same with any different IDs, I tried sending message 3 times, this guarantees delivery of payload, but it using too much power

    Now I use power supply with 1117

    But my other nodes powered by CR2032 with boost 0.8-3.3V dc/dc with inductor coil on the NRF24 supply pin without any troubles

    He means radio range (distance) not ID of node 😉

  • @nca78 oke, undestood
    Problem stiil not resolved. I want to send message again to the gateway if NACK but dont know how to do it.

    send(msg.set(value == HIGH), true); 

    in this case i have additional ack log in the serial debug, nothing more

  • Mod

    The send function returns a value, so you can check if it was successfully sent or not and in case retry

  • Plugin Developer

    A quick ACK example:

            static boolean tryAgainLater = false; // should we resend?
              Serial.println(F("Received ACK"));
              tryAgainLater = false;
            }else {
              Serial.println(F("Connection problem, try again"));
              tryAgainLater = true;

  • Mod

    There is no need to set the second parameter to send() to true. That parameter is unrelated to the return value (except very unfortunate similar naming). More info: https://github.com/mysensors/MySensors/issues/1103

  • Plugin Developer

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


    Ah, thanks. So ACK basically always happens?

    in that case, do you have any better example code on how to check if the ACK is received?

  • Mod

    @alowhum on nrf24, "hardware" ack is always on. "Software" ack is controlled by the second parameter in the send() function. Read https://forum.mysensors.org/post/34267 for an attempt to sort out the details. It is still quite confusing for me.

  • What will happen if i cut the power OFF of the radio after each transmission? is it needed to be initialize again before next transmission?

  • Mod

    @tiana yes.

    But don't cut the power. Use transportDisable and transportReInitialize instead.

  • Do you know how much will be power usage in transportDisable mode?

  • Mod

    @tiana depends on which transport you are using, and if using genuine or clone chips. The nrf24 is rated for 900nA.

  • Thanks for fast reply, actually 900nA is to big number and i prefer to use xxx_POWER_PIN to cut the power of the NRF module.
    I am building switch powered with CR2032 battery and i want to extend battery live as much as possible, for a switch is not needed to keep radio alive, i need it ON only when transmit signal

  • Mod

    @tiana 900nA on a cr2032 is 27.9 years battery life. The self discharge of a cr2032 is around 250nA.
    But yes, use the power pin setting if you want to.

    Would be interesting to see how long sleep times are needed to make up for the extra time needed to wake up the radio from power off compared to sleep. The mcu and the radio will need to be awake for 100ms longer time when starting from power off than when starting from sleep.

  • Hi I notice that there is not sleep in this sketch. Is it not required for this build

  • Mod

    @terence-faul the sketch will work as-is, as long as the node has a constant power supply. If you want a battery-powered node, you'll need sleep. See earlier discussions in this thread for ways to add sleep.

  • Hi
    Can i connect two sensor contact to this arduino ? First to pin 3 second to pin 4 ? But how modified this sketch to support two sensor contact ?

  • @pepson If you need the node to sleep or want to use interrupts then only digital pins 2 and 3 will do this for uno/promini.

    So otherwise 2 options really.

    If you just need to know that one of the sensors triggered (but not which one) then you can add sensors in series (for normally 'closed' sensors) or parallel (for normally 'open' sensors).

    To use interrupt and know which sensor triggered you'd have to connect both sensor to interrupt pin with blocking diodes to digital pins as well and then on interrupt you can check which digital pin activated the isr.

  • I need connect two contact sensor. And i want to know from two sensor his status...
    I need use one to door but second to door garage.
