My doorbell, which I want to make smarter<\/figcaption><\/figure><\/div>\n\n\n\n

I live in tall and skinny house with a loft on the upper floor. I can’t hear the doorbell going off when I’m up there, especially if I have music playing. This post is about how I extended the range of my doorbell by hooking a sensor up to it that communicates over Wifi to my smart-home, which then plays a doorbell tone over my speakers throughout the house. <\/p>\n\n\n\n

I already have a reasonably capable smart home<\/a> based on Home Assistant<\/a>, so I challenged myself to do this in the cheapest, least intrusive way possible. In the end, I did this with a $7 part and without changing any of the wiring in my existing doorbell (I just had to connect 2 extra wires to the existing transformer).<\/p>\n\n\n\n

Here’s a preview of it working:<\/p>\n\n\n\n
