<p>This doorbell housing fits a 30mm <i>Momentary Reset Short Metal Push Button </i>such as the one I used from this <a href="https://www.aliexpress.com/item/4000310874353.html?spm=a2g0o.order_list.0.0.6ef01802MIGp6L">AliExpress link</a>. Print the model face down and then apply multiple coats of spray paint for weather resilience. Wire the button using some cable (I used some CAT5e), then run it to the microcontroller of your choice, I used a <a href="https://www.wemos.cc/en/latest/d1/d1_mini.html">Wemos D1 Mini</a> and <a href="https://esphome.io/index.html">ESPHome</a>.
