The Doorbell Modernizr is a device that can transform your ordinary doorbell into a "smart" wifi connected doorbell. Whenever someone presses your doorbell, the Doorbell Modernizr can send a signal to your home automation system (currently supported: Home assistant, Domoticz and Openhab).
With this signal you can create automations to, for instance, send a notification to your phone, take a snapshot with a camera, or anything else you can think of.
The inspiration for this device came from the Home assistant community, especially from the circuit thought out by user TisGoud, available in the documentation link below.
The Doorbell Modernizr comes assembled and pre-programmed with a 3D printed housing, or you can choose to assemble it yourself. The Doorbell Modernizr needs a 5V 1A power supply with a 5.5mm barrel jack, you can order it as a optional extra here, but the price is a bit high because of the shipping costs, you might be better of ordering one here
The device should be connected in parallel with your existing doorbell
Most doorbell transformers use AC, so it doesn't mater how you connect the wires of the doorbell to the board, there are however some cases in which the doorbell does use DC. In that case you need to make sure the + wire of the doorbell is connected to the left side of the screw terminal and the - to the right side.
All instructions can be found in the manual
There are a few different versions around, the current version I sell is version 2.0
Version | changes | flaws |
---|---|---|
1.0 | none | |
1.1 | Slightly updated version with protection for different adapter polarity | none |
1.2 | Changed optocoupler pin to 16 , added header for I2C devices/sensors, added button for resetting wifimanager settings | Pins on the I2c header for SDA/SCL are the wrong way around. Pin 16 does not have a internal pull-up resistor, therefore a thru hole resistor needs to be soldered on the back of the board between the octocoupler and vcc. I will include the resistor in the kits and fully assembled versions |
1.2a | Changed optocoupler pin to 14 , resolved issue of the I2c header | none |
2.0 | Same as 1.2a, but now professionally assembled | none |
The Doorbell Modernizr is based upon the popular ESP8266 microprocessor. If you like, you can program it yourself with your own software, for instance with the Arduino IDE. To program the module, you need an FTDI module to program it through USB. There’s a header on the board to plug the module into. On the board you can find a small “program” switch. To program the module, plug in the FTDI module, set the switch to “on” and apply power.
to program the board, you will need a FTDI module, like this one
If you click on "source code" at the bottom of this page, you'll find a sample where the board is used to send on/off mqtt messages to home assistant.
The Doorbell Modernizr is open source, you can find the Arduino source code, STL files for the housing and gerber files for the board on github
