The previous de1app version was released in October. Here's what's new in this version:
New workflow for bluetooth scales
when the DE1 is put to sleep, the de1app auto-disconnects from your scale, so you can power it off. This greatly extends the battery life of your scale.
When you wake your DE1 from sleep, it will auto-connect, so it's good to power the scale on before or soon after waking your DE1.
If you have a Decent Half Decent Scale or full height Decent Scale v1.2, the scale it automatically powered off when the DE1 goes to sleep
if you want the de1app to stay connected, even if the DE1 is sleeping, go to Settings->App->Misc and enable “keep scale connected”
Stop-at-weight won't get triggered during preinfusion steps
allowing you to move your cup placement during preinfusion
Also: the word “tare” in a profile's step message, will retare the scale to 0g at that point in espresso making. This allows a profile to allow a cup to to be placed on the scale after the espresso has been started. However, most profiles have not been rewritten to allow this feature, as it's unclear how needed it is (ie, you started espresso before putting a cup on the scale)
App Auto-update
If your DE1 is asleep in the middle of the night, and you're connected to wifi, de1app software updates are auto-downloaded, and will be applied the next time you tap OK in the Settings page.
You can disable this in Settings->App->Misc.
Your stable/beta/nightly setting (in Settings->App->Misc) determines which app updates you are getting.
All the original 3 stage profiles that had ~4ml/s preinfusion, have now been changed to be 8ml/s
A consensus has been arrived at, that slower preinfusion tends to cause more channeling and worse shots.
Added support for more bluetooth scales: “Eclair” scale by Atomheart (Taobao link), Solo Barista scale LSJ-001, Varia AKU scale.
Allowunusual screen resolutions of Samsung tablets to be set using Settings->App->Resolution.
Specifically: the “a7 lite” is 1340x800, the “a9+” is 1920x1200, the “s9 ultra” is 2560x1848.
Two new espresso profiles: Damian's “Q” (best for medium-light roasts) and John Weiss' “Advanced Spring Lever”
Many Streamline skin v1.0 bugs fixed, it is now considered “fit for general use”.
And new in v1.46.1
This is mostly a “small usage improvements” and “bug fixes” release to the stable version of the de1app.
General Improvements:
SAV (stop at volume) is disabled if a scale is connected, and SAW (stop at weight) is then exclusively used.
Previously SAV would stay active even if a scale was present, which could cause an early shot ending.
Cool-down screen saver changes from allowing “disabled to up to 2 hours” to “1 minute up to 8 hours”
screen burn in has been observed on some tablets that disable the screen saver, so people should not disable their screen savers.
When the app exits automatically after SETTINGS OK button is pressed, due to an app update pending**, a message “The app is being updated.”** is now displayed, to make the reason for this exit clear.
Settings: the two fields in LIMITS for advanced shots, that define volumetric stopping, have changed their wording, to be clearer that they define when preinfusion ends in a shot.
The new fields are: “Preinfusion ends after:” and “After Preinfusion, stop the shot at”
Samsung tablets now do a one-time-one default setting for fonts and resolution when the de1app detects itself running on the tablet for the first time.
Using Samsung a9+ tablet automatically sets de1app to its correct resolution, and defaults to font scale of 0.65, allowing user to set font scale between 0.6 to 0.8, resetting to 0.65 if out of those bounds.
Streamline improvements:
profiles now save Grinder Setting and Grinder Dose.
show scale weight of water dispensed while dispensing hot water
if the steam heater is disabled by you (or still heating, and under 120ºC) steaming is cancelled and a message displayed. If under 135ºC but over 120ºC, then a “please wait”message is displayed.
General bugs fixed:
fix bluetooth connectivity issues for older Acaia Lunar scale
DYE: fix bug where OK button in history viewer didn't work, causing you to have to kill the de1app to get out.
Settings: profile listbox should always be left-aligned, even in Arabic. Doing otherwise causes bugs.
Fixed the broken stop-on-weight for hot water dispensing
Improve starting estimate for DiFluid and avoid cross-scale contamination of period estimation
DSX: added files for 1340x800 tablet resolution
Streamline bugs fixed:
First time using Streamline skin could cause an error
if the “your steam is too hot” message appeared when using Streamline skin, then a grey page followed and you'd have to force quit the app to continue.
Double-tap on a profile to edit it, now works correctly with DFLOW and AFLOW profiles
Fix error message with DYE running with Streamline skin
Hot water feature was showing the setting for hot water, but not the actual output
You were previously allowed to enter a 0ºC brew temp, which the DE1 does not recognize as valid. Now, you can enter in 1º but no lower. This effectively turns off the brew heater, so you can make room temperature espresso, if you want to.
