After you have been using Loop for a while, there's a potential that you will run across a behavior or issue that you wonder if it is normal or intended. When that happens, there are a few things that we'd recommend doing to resolve the issue.
Check the Docs⌁
The Loop docs are updated regularly. If you built your Loop app awhile ago, chances are good that more information has been updated and changed since you first read them. Please can the topics and look for a section that may be applicable. For example, if your Nightscout isn't working, try looking at the docs there. A good read of ALL the pages at the beginning of using Loop is encouraged. Many FAQs from new Loop users are covered in the docs.
Take a screenshot of your Loop main display screen, or other screens (such as Tuning results of RileyLink) that may help troubleshooters better understand your issue. A lot of times a picture is worth a thousand words. Being able to see recent Loop basal adjustments, predicted BG curve, and carb entries really help fill in the full story of the current Loop status. If you didn't manage to get a screenshot when the issue was happening, you can also go to Nightscout and scroll back over the previous 48 hours to obtain much of the same information. Try to capture a Nightscout screen from the time period in question.
Under the Loop app settings, there is a selection called
Issue Report. Within the Issue Report are important information about your Loop's actions and status that can be very useful for troubleshooters...particularly with unexplained behaviors. The upper right corner of the Issue Report includes a button so that you can email the Issue Report to yourself (or others). If you are seeing something unusual in your Loop, capture an Issue Report while it is happening and save it. A troubleshooter may want to see that information.
Check the current list of GitHub Loop Issues for known issues. Many times other users have noticed the same issue previously and opened an Issue so that more information can be added to help develop a solution. If you see your same issue has already been reported, please add to the open issue instead of creating a new one.
Zulipchat and Facebook⌁
Ask for Help⌁
If you can't find any information in the Loop docs, GitHub Issues, Zulipchat, or Facebook...PLEASE post and ask for help. GitHub Issues list is an EXCELLENT place to post issues of unexpected Loop behavior (that you believe are errant or need improvement). However, if you are just seeking clarifications on Loop, but don't necessarily expect that there's a problem with the underlying code, then Facebook and Gitter would be a good place. For example, Zulipchat and Facebook are great for asking about bolus strategies or exercise target use...those aren't really code issues.
When you post, provide a description along with any screenshots of the issue you are having. You don't necessarily have to tag any particular person, the community is fairly active in replying to messages.
