Homeassistant Entity: Spacebutton
Homeassistant Sensors: 
Primary Button -> Big Button 
Secondary Button -> Small Button
To reconfigure pins, change them in the Tasmota interface. It's important to set them to "Switch".
Tasmota by default tries to link relays to the switches, to decouple use 
Setoption 114
By default, the Off point on the big switch (and the down pointing of the little switch) are interpreted as on, and vice versa. To change that, use 
SwitchMode1 2 and 
SwitchMode2 2 respectively.
