**This software is part of a DIY solution and is not a product, but
requires YOU to read, learn and understand the system and how to use it.
You alone are responsible for what you do with it.**
Hardware requirements:
- A Roche Accu-Chek Combo (any firmware, they all work)
2017-11-21 10:53:47 +01:00
- A Smartpix or Realtyme device together with the 360 Configuration
Software to configure the pump.
Roche sends these out free of charge to their customers upon request.
2017-11-22 22:16:24 +01:00
- A compatible phone: An Android phone with a phone running LineageOS 14.1
(formerly CyanogenMod), or possibly stock Android >= 8.1 in the future.
- To build AndroidAPS with Combo support you need the lastet Android Studio 3 version

Limitations:
2017-11-06 23:15:36 +01:00
- Extended bolus and multiwave bolus are not supported.
2017-11-22 15:20:07 +01:00
- Only one basal profile is supported.
- Setting a basal profile other than 1 on the pump, or delivering extended boluses or multiwave
boluses from the pump will disable the loop functionality for 6h as the the loop can't run
safely under those conditions.
2017-11-21 10:53:47 +01:00
- If multiple boluses are given within a single minute, only one might
be recognized. This is due to the Combo saving history records with
minute-precision only. However, this case is only possible for very
small boluses and is unlikely to occur in non-testing scenarios
(e.g. bolusing from the pump and then immediately bolusing from AAPS).
2017-11-22 15:20:07 +01:00
- If a TBR is set on the pump, AAPS will cancel it. This is because it's not possible to determine
the start point of a TBR until it is finished or was cancelled at which point a record in the
2017-11-23 20:53:58 +01:00
pump's history is created. Before that, there is none and it's simply not possible to determine
2017-11-22 15:20:07 +01:00
the TBRs influence on IOB. Set TBR using AAPS instead.
- It's currently not possible to set the time and date on the pump (only reading the time - but
not the date - is supported raises a warning in AAPS to update the pump clock manually).
Thus, the pump's clock must be updated manually when the clocks are turned forward/backward
for daylight saving time.
Setup v2:
- Configure pump using 360 config software.
2017-11-23 20:53:58 +01:00
- Set/leave the menu configuration as "Standard", this will show only the supported
menus/actions on the pump and hide those which are unsupported (extended/multiwave bolus,
multiple basal rates), which cause the loop functionality to be disabled when used because
it's not possible to run the loop in a safe manner when used.
2017-11-22 15:20:07 +01:00
- Set maximum TBR to 500%
- Disable end of TBR alert
- Set low cartridge alarm to your licking
- Enable keylock (can also be set on the pump directly, see usage section on reasoning)
- Get Android Studio 3
2017-11-22 15:20:07 +01:00
- Get ruffy from https://github.com/jotomo/ruffy (branch `combo-scripter-v2`)
- Pair the pump, if it doesn't work, switch to the `pairing` branch, pair,
then switch back the original branch. If the pump is already paired and
can be controlled via ruffy, installing the above version is sufficient.
If AAPS is already installed, switch to the MDI plugin to avoid the Combo
plugin from interfering with ruffy during the pairing process.
2017-11-22 15:20:07 +01:00
- Get AndroidAPS from https://gitlab.com/jotomo/KEF (Branch `combo-scripter-v2`)
- Before enabling the Combo plugin in AAPS make sure you're profile is set up
correctly and your basal profile is up to date as AAPS will sync the basal profile
to the pump.
- There might be minor glitches around enabling/disabling the Combo plugi, requiring
to restart AAPS by force-closing it.

Usage:
- This is not a product, esp. in the beginning the user needs to monitor and understand the system,
its limitations and how it can fail. It is strongly advised NOT to use this system when the person
using is not able to fully understand the system.
- The integration of the Combo with AndroidAPS is designed with the assumption that all inputs are
made via AndroidAPS. While there are checks that will detected boluses entered directly on the
pump, which will be added to the history and be included in IOB calulations, there are delays
until AAPS becomes aware of those bolusus (up to 15m). It is therefore strongly adviced
to only bolus via AndroidAPS (it's also only possible to enter carbs via AndroidAPS, required for
advanced loop functionality).
- It's recommended to enable key lock on the pump to prevent bolusing from the pump, esp. when the
pump was used before and quick bolusing was a habit.
Also, with keylock enabled, accidentally pressing a key will NOT interrupt a running command
2017-11-22 15:20:07 +01:00
- When a BOLUS/TBR CANCELLED alert starts on the pump during bolusing or setting a TBR, this is
caused by a disconnect between pump and phone. The app will try to reconnect and confirm the alert
and then retry the last action (boluses are NOT retried for safety reasons). Therefore,
such an alarm shall be ignored (cancelling it is not a big issue, but will lead to the currently
active action to have to wait till the pump's display turns off before it can reconnect to the
pump). If the pump's alarm continues, the last action might have failed, in which case the user
needs to confirm the alarm.
- When a low cartridge or low battery alarm is raised during a bolus, they are confirmed and shown
as a notification in AAPS. If they occur while no connection is open to the pump, going to the
combo tab and hitting the Refresh button will take over those alerts by confirming them and
showing a notification in AAPS.
- For all other alerts raised by the pump: connecting to the pump will show the alert message in
the Combo tab, e.g. "State: E4: Occlusion" as well as showing a notification on the main screen.
An error will raise an urgent notification.
- After pairing, ruffy should not be used directly (AAPS will start in the background as needed),
since using ruffy at AAPS at the same time is not supported.
- If AAPS crashes (or is stopped from the debugger) while AAPS and the pump were comunicating (using
ruffy), it might be necessary to force close ruffy. Restarting AAPS will start ruffy again.
- Read the documentation on the wiki as well as the docs at https://openaps.org
- Don't press any buttons on the pump while AAPS communicates with the pump (Bluetooth logo is
shown on the pump).
- If the loop requests a running TBR to be cancelled the Combo will set a TBR of 90% or 110%
for 15 minutes instead. This is because cancelling a TBR causes an alert on the pump which
causes a lot of vibrations.
- Long press the Refresh button on the Combo tab to force a re-read of all pump data

Reporting bugs:
- Note the precise time the problem occurred and describe the circumstances and steps that caused
the problem
- Note the Build version (found in the About dialog in the app, when pressing the three dots in the
upper-right corner).
- Attach the app's log files, which can be found on the phone in
