Nice project. Even though some items are in a language I do not understand, the sketch provided me with a better understanding of the MySensors work. Thank you for making the connection of what I know and what I was having trouble understanding.
@OldSurferDude
yeah, 10 virgin nodes powered up at the same time is a bad idea I seem to remember reading somwewhere here warning aginst that.
If yu have node ID trust issues with Mysensors you should move your address to different locaion as 0x00 is used by Mysensors... just sayin..;)
@Paul-Scarbro There are multitude of solution, but since we are in MySensors Land, let's do a MySensors solution. You'll quickly see that doing that adds a lot of overhead.
We'll use an Arduino Nano or RF Nano if you're going to go whole hog. It can be run from 3.3V or 5V DC, not AC.
The reed switch would be connected to an input of the Nano and one of the outputs would drive a relay. The relay would drive the chime.
Your C++ program would be something like:
#define inputButton 2; // connect reed switch here
#define outputRelay 4; // connect relay to this pin see MySensors Relay example
#define RELAY_ON 1 // GPIO value to write to turn on attached relay
#define RELAY_OFF 0 // GPIO value to write to turn off attached relay
void setup() {
pinmode(inputButton,INPUT);
pinmode(outputRelay,OUTPUT);
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
if (digitalRead(inputButton) == 0) {
digitalWrite(outputRelay,RELAY_ON);
wait(2000); // wait 2 seconds
digitalWrite(outputRelay,RELAY_OFF);
// now wait for door to close
while(digitalRead(inputButton) == 0) ; //does nothing until reed switch opens
}
}
There are some subtleties that I may have glossed over, but this is the gist.
By looking at the MySensors Relay example, you'll see how to integrate this into a MySensors environment. That's where you'd want to get the RF Nano.
I've made the assumption you're familiar with the Arduino IDE and you've looked into the MySensors environment.
@OldSurferDude I use this. https://www.homedepot.com/p/Orbit-Solenoid-for-Battery-Operated-Timer-57861/203151515
Instead of having to hold the valve open, i can just pulse it. I use a simple motor controller to pulse it and when i need to close it, pulse it in "reverse". That way I could use a battery and if it only opens once or twice a day it's only a half a second or so of draw off the battery.
