Nightscout

What

Nightscout (CGM in the Cloud) is an open source, DIY project that allows real time access to a CGM data via an HTTP REST API. It is used for secure remote viewing of blood sugar data from anywhere...including Oh My Posh segments on the command line!

Sample Configuration

This example is using mg/dl by default because the Nightscout API sends the sugar glucose value (.Sgv) in mg/dl format. Below is also a template for displaying the glucose value in mmol/L. When using different color ranges you should multiply your high and low range glucose values by 18 and use these values in the templates. You'll also want to think about your background and foreground colors. Don't use white text on a yellow background, for example.

The foreground_templates example below could be set to just a single color, if that color is visible against any of your backgrounds.

Or display in mmol/l (instead of the default mg/dl) with the following template:

"template": "\ue2a1 {{ if eq (mod .Sgv 18) 0 }}{{divf .Sgv 18}}.0{{ else }} {{ round (divf .Sgv 18) 1 }}{{ end }}{{ .TrendIcon }}"

Properties

Name	Type	Default	Description
url	string		Your Nightscout URL, including the full path to entries.json AND count=1 AND token. Example above. You'll know this works if you can curl it yourself and get a single value
headers	map[string]string		A key, value map of Headers to send with the request
http_timeout	int	500	in milliseconds - how long do you want to wait before you want to see your prompt more than your sugar? I figure a half second is a good default
cache_timeout	int	5	in minutes - how long do you want your numbers cached?

info

You can change the icons for trend, put the trend elsewhere, add text, however you like! Make sure your NerdFont has the glyph you want or search for one.
