Acaia's _H2O_ feature

Yesterday evening, mr Rex Tseng, CEO of Acaia, manufacturer of highly specialized scales for baristas, came to visit. We enjoyed some espressos from Cameroon Boyo washed Asuchuf village java arabica beans that I roasted on the Coffee-Tech FZ-94 last week and we chatted about  lot of developments in the coffee arena. 

Mr Tseng showed the prototype of a scale they are developing for the Sanremo Opera espresso machine. On the three group machine, each brew group has its own device that exactly fits into the drip tray and each one communicates wireless with the electronics inside the linked brew group.

One other device he showed is a setup for pour-over coffee which is basically a Lunar scale tracing what's being extracted into the cup over time, with the pour-over device including the filter and the Lunar sitting on the larger Pearl scale and a new Acaia app that communicates with both scales at the same time, showing exactly what's happening in a way that has not been monitored before. In one realtime graph on screen you can log how much water is poured on and also what flow profile it generates into the cup and how much water remains inside the filter, soaked into the grinds.

There's even more (another very nifty app) but that will be published in due time.

In the video that I made, you can see how the Acaia "Lunar" scale and the prototype of its upcoming cousin/big brother (designed for the Sanremo Opera espresso machine) have a feature that tells the user when the reading may be momentarily off due to flooding. The internal mechanics and electronics won't be damaged but in worst case (if the H2O message keeps appearing) you might need to keep the scale in a dry room overnight. In this short spontaneous video I made when mr Rex Tseng of Acaia visited my coffee place, he demonstrates how/when this H2O message might briefly appear. He also demonstrates how the new scale is heat/water resistant, with a skin on top of the scale that allows the water to quickly disperse.
