For the serious home espresso brewer, the Automatic Shot Timer from Luminaire Coffee Equipment in Seattle is a revelation.⁠⁠
⁠⁠
This timer automatically starts when you start the shot brewing on your espresso machine and stops when the shot finishes. It can be retrofitted to almost any espresso machine that uses an AC Solenoid Valve to control water flow to the coffee group. ⁠⁠
⁠⁠
For the home espresso aficionados, this includes the following domestic machines:⁠⁠
⁠⁠
1. La Marzocco Linea Mini 
2. La Marzocco Linea Micra 
3. Rancilio Silvia
