How To - Doorbell Automation Hack
-
@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.

So got my doorbell up and working. Here's the details: I used the mini RBoard and it's working out great.
I soldered the cap directly onto the nrf board. Unfortunately, that board overhangs the A0 connections on the rboard (there's 2 pins there, one is the A0 pin and one is a ground). Thankfully, it only ACTUALLY covered the ground, so it was easy to work around. The brown wire in the photo is the wire I have connected to the A0 pin. The green wire is a temp wire I was connecting to the ground in the serial connections.
In the doorbell, I cut away one of the panels over one of the resonant chambers since I saw that the module would fit in there perfectly. I then wired it up and tucked it away. I did lose a little volume since the chamber is filled rather than resonating, but it's worth it to have the doorbell notifying my Vera system. That can flash lights and so forth to notify us other ways - we couldn't usually hear the doorbell when downstairs anyway.
Code wise, I used the original code above with just a couple minor changes. I set the doorbell_pin to A0, the relay_pin to 4, and the node_ID to auto. I also set it to act as a repeater since it's hardwired to power. Now that I have it working, I wish I'd changed the ringTime to a lower value since 7/10 of a second is way longer than the doorbell normally takes between the two notes, but it's not a big deal. Not worth pulling the board out, disconnecting it, reprogramming it, and reinstalling everything :-)

My wiring:
I discovered that they ran 4 conductor wire from the transformer in the basement to this location. So I plugged a phone charger in near the transformer, cut the end off a USB cable, and connected the 5V and gnd wires from that USB cable to the spare 2 wires in the cable. So then there's 6 wires coming into the doorbell as shown here: 2 for 16VAC from the transformer, 2 for 5VDC from the phone charger, and 2 from the doorbell button. I then connected the 5V pair to the top pair of screw terminals in the photo on the rboard. They're the blue and green wires. The white wire in the top terminal is one side of the button, connecting to ground there. The second side of the button is the red wire going into the grey wire nut. The brown wire coming out of the nut connects to the A0 pin on the board. Finally, the 2 16VAC wires are red and white. The red goes over to the right terminal on the plunger mechanism. The white goes to the common terminal on the rboard's relay connections. Finally, a black wire connects the NO from the relay to the other side of the plunger.
Hopefully that was all clear for anyone wanting to wire up their own!
