The S1 Cafe - Helping Your Espresso Dreams Become Reality

12 1/2 years later I finally have done this! :) Thanks to bgour for the support. Settled on an esp8266 + relay, which per this thread was soldered to the pins on the back of the button board. Perhaps ~2 hours build/install time if you move efficiently. I used the example Wemos relay code to start an...

Teflon tape acceptable? Didn't seem like there was any on it from the factory circa 2006

Long time owner and S1Cafe person, just not active. Had to replace the pump and motor due to the dreaded leak and corrosion issues.

Hey folks, long time owner of an original S1 V1 but haven't been on the forum in a long time.
