## Configuring Automatic Sensitivity Mode

For more information review https://github.com/openaps/oref0/issues/58

1)	Ensure to get the latest dev branch
```
cd
cd src
cd oref0
git pull
git checkout dev
sudo npm install -g
```
Make sure you run the last line to install the tools

2)	Next in order to properly execute the new auto-sensitivity module, you need to have at least 24 hour worth of pump history data and enough bg readings (past 24 hours).
In your openaps.ini apply the following changes:
```
[report "[Your Path]/glucose.json"]
device = cgm
use = iter_glucose
reporter = JSON
count = 288
```

Note: If using Nightscout add count=288 to your entries.json API call as a querystring parameter
For NS it will look something like this depending on how you implement it (note the ?count=288)  that is what you have to add
```
[device "curl"]
fields = 
cmd = bash
vendor = openaps.vendors.process
args = -c "curl -s https://[Your URL]/api/v1/entries.json?count=288 | json -e 'this.glucose = this.sgv'"
```


If your [glucose.json] does not have enough entries you will see a warning when running your auto-sens.json report "Error: not enough glucose data to calculate autosens."

3)	After applying the above change you need to add a new device and report as follow:
```
[device "auto-sens"]
vendor = openaps.vendors.process
extra = auto-sens.ini
```
and your auto-sens.ini should look like this:
```
[device "auto-sens"]
fields = glucose pumphistory insulin_sensitivities basal_profile profile
cmd = oref0
args = detect-sensitivity
```

4) Next create this report
```
[report "[Your Path]/auto-sens.json"]
profile = [Your Path]/profile.json
use = shell
reporter = text
json_default = True
pumphistory = [Your Path]/pump-history-zoned.json
basal_profile = [Your Path]/active-basal-profile.json
insulin_sensitivities = [Your Path]/insulin-sensitivities.json
glucose = [Your Path]/ns-glucose.json
device = auto-sens
remainder = []
```

5) Next we need to pass auto-sens.json to oref0-determine-basal.json, in openaps.ini add a new input simillar to folowing example below:
```
[device "oref0-determine-basal"]
fields = iob current-temps glucose profile auto-sens meal
cmd = oref0-determine-basal
vendor = openaps.vendors.process
args = 

[report "enact/suggested.json"]
profile = [Your Path]/profile.json
use = shell
reporter = text
current-temps = [Your Path]/temp-basal-status.json
device = oref0-determine-basal
iob = [Your Path]/iob.json
glucose = [Your Path]/glucose.json
meal = [Your Path]/meal.json
auto-sens = [Your Path]/auto-sens.json
```

6) Next you have to make sure you pull 28 hours (24h + DIA) of pump history.  Change the hours to 24, so your pump history report should look like this:
```
[report "[Your Path]/pump-history.json"]
device = pump
hours = 28
use = iter_pump_hours
reporter = JSON
```
Note. Your loop should run without auto-sens.json report but if you don't pass that as an input you will see the following message while executing oref0-determine-basal.js:

Optional feature Auto Sensitivity not enabled:  { [Error: ENOENT: no such file or directory, open 'online'] errno: -2, code: 'ENOENT', syscall: 'open', path: 'online' }

Here is an example of running the loop with Auto Sensitivity feature enabled:
