I like the programmable grey target idea 👍
Got any input on the meaning of those audible cues? Utilizing the audible facet is wise.
And the analog look is nice to have as an option.

Good ears!
The audible notifcations can be individually turned on/off.
They are for "Preheated", "Shot Start" and "Shot Complete".
>> With the pressure sensor and the balance connected
Automatically starts when
* The pressure reaches the program starting pressure.
Automatically stops at two minutes, or earlier when
* The shot timer exceeds ½ the program duration, and
* The pressure returns to the program ending pressure, and
* The mass exceeds ½ the program target mass, and
* The flow rate is less than 0.01g/s.
Automatically resets
* One minute after the shot stops.
>> With just the pressor sensor connected
Automatically starts when
* The pressure reaches the program starting pressure.
Automatically stops at two minutes, or earlier when
* The shot timer exceeds ½ the program duration, and
* The pressure returns to the program ending pressure.
Automatically resets
* One minute after the shot stops.
>> With just the balance connected
Automatically starts when
* The mass exceeds 0.1g.
Automatically stops at two minutes, or earlier when
* The shot timer exceeds ½ the program duration, and
* The mass exceeds ½ the program target mass, and
* The flow rate is less than 0.01g/s.
Automatically resets
* One minute after the shot stops.
>> Notifications (sound)
At the start and end of a shot
When the temperature reaches the preheat temperature of the current program.
* It will only sound again if the temperature first drops 10°C below the preheat temperature.

talking to an acai scale and measuring yeild could be perfect touch xD

[@JohnMichaelHauck]

The app already does that, and also the decent scale. I'll post a video soon.

[@JohnMichaelHauck]

I just posted a video with the acaia pyxis scale.

How do you get your handle to move up and down so easily? Mine always gets so stiff. I've never found a cure.

[@JohnMichaelHauck]

By taking the piston out of the group head and lubricating or replacing the gaskets. Look for a food safe high temperature lubricant.

@@JohnMichaelHauck mmm, that is quite a maintenance schedule. And although I've just ordered some silicon grease, can't say I'm thrilled at the thought of it coming into contact with the water for my coffee.
