Dash Button DIY with ESP-01

I've been looking for a DIY dash button for my FHEM SmartHome system for a long time. Here on Thingiverse I found this [ESP8266 IoT Wifi] button (https://www.thingiverse.com/thing:2803769).

I really liked the design of the case as well as the possibility to operate it via MQTT.

Since I still had ESP-01 and CR2032 at home, I got down to work.

components:
