💬 Door, Window and Push-button Sensor

[skywatch]

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! :)

[mfalkvidd]

@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?

[skywatch]

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

[skywatch]

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?

[joseyapor]

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

[mfalkvidd]

@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.

[Ed1500]

@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? :(

[LastSamurai]

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)

[Euromir]

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.

[bluezr1]

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.

[skywatch]

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?

[Psilin]

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?

[Slimz]

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?
Thanks!
Jim

[Steve Hadley]

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

[rodaman]

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.

@rodaman

I fixed it for you.

[rodaman]

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

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

What is the purpose of the buttonPin-array?

E.g.

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...
