How To - Doorbell Automation Hack
-
Hi @hek
I'm not too sure I understand what you are referring to. If you are referring to the buttons themselves outside being wireless, I thought about it but wasn't too sure how long a battery would last and didn't want to be changing batteries. The way I plan to do this now, I can use the existing wiring for the doorbells that are already there, and splice into the power for the door bell to power the MySensors node.
Plus, both chimes are in the same spot, one relay sets off one set of the three contacts (Wtih a common ground I believe) and the other will chime the second.

Ahh. nice. Thought you might have to run some new wires around the house.

@drock1985 Nice! Does your doorbell use DC so you can steal power from it? I wish mine did. That would have made things easier for me. Mine uses 16VAC... :(

Hey @petewill
They vary. Some of the more expensive ones I've noticed use DC (ex play custom songs/tones), while the cheaper ones use AC.
I built the project around the idea the wife would want something more elaborate than a simple ding sound, but I was wrong lol. So I picked up one that she looked last night, and I believe it uses AC, so I will be making a slight change to my design.
I'll end up putting in one of these I figure, just haven't quite figured out what size smoothing capacitor I will need.
Also, I'm not 100% sure yet (at work, hard to do research) but I may be able to get away with a simple 5v regulator once the power is converted to DC, in lieu of a variable buck converter.

@BulldogLowell Haha, I just took the easy way out and ran a 5V line :)

Yeah, that's happened to me as well on other projects :)

Add a cap .1uf input side of the 5V regulator and a 47-220uf on the regulated 5V . High freq and a low freq ripple.
That should do the trick same thing I was planning on doing. I bought the Ring Doorbell but still want to be notified of the actual ring into HA.

Hi @petewill
I finally got the parts in to do the project. I've been working on the code, but I seem to be running into an issue. I have the four devices show up in Domoticz, but I'm not getting any feedback from the sensor. Would you mind looking at the code for me please? This is the first program I have ever worked on, and not much of a programmer mentality yet.

debouncer.attach(DOORBELL1_PIN); debouncer.attach(DOORBELL2_PIN);do this instead:
//... Bounce debouncePin1 = Bounce(); Bounce debouncePin2 = Bounce(); //... void setup() { //... debouncePin1.attach(DOORBELL1_PIN); debouncePin1.interval(5); debouncePin2.attach(DOORBELL2_PIN); debouncePin2.interval(5); //... }and update the state with:
debouncerPin1.update();get it?
alternatively you could use an array:
Bounce debouncer[2] = Bounce();it would make your code a lot easier, but you have to understand arrays and Classes or you will be a little lost.

Haha, I just took the easy way out and ran a 5V line
that may be the easy way, but not as fun :(
-
I did take a look at my doorbell last night. I have a transformer down in the basement that's outputting 16VAC. Then the doorbell upstairs, with no convenient place to get power from. The wires from both the doorbell button and the transformer come to the doorbell "box" on the wall.
At first I was looking for a way to convert the 16VAC to 5VDC. Then as I was looking at the space in the doorbell to mount the board, I saw two more wires not connected to anything. They ran 4 conductor wire from the transformer to the bell! Sweet! So now I'll put a 5V source (probably phone charger to USB cable with the end cut off) in the basement, connect that to the other unused pair of wires, and have my power where I need it.
Is there any issue with running the 5V DC power and the 16VAC power alongside each other? It's not like either is carrying data, so I don't think there would be...

Hi,
Just a quick question. I'm trying the original code for the doorbell, and I have it registering in Domoticz just great,. I have two lights, one to turn off the relay and the other, not sure of (thought it would turn on if doorbell was tripped). Anyways, did I miss something or did domoticz register it as the wrong item?
Thanks,

@drock1985 I have mine registered as a motion sensor. So when the button is pressed it shows tripped. It will only show tripped for one second though so maybe the Domoticz UI isn't updating fast enough?
-
Been looking into this, not sure what the problem is. I changed over the motion sensor settings in Domoticz so that it would stay on for 5 seconds after being tripped, but it never registers the change. I can turn the chime itself on and off no problem, just no alert.
This is the output from serial monitor in Arduino with the doorbell sensor. The sensor acknowledges the change in switch state (for muting the chime) but doesn't for the action of the button being pushed. Doesn't appear to be a message being sent out either.

Well, I got it to work. Had to add a gw.send command to the code. The below is for the original 1 door chime that @petewill has created. I have added the code to make this compatible with Domoticz.
