+The oref0-setup option for `xdrip-js` installs Logger by default. However, you should be aware that Logger has it's own configuration settings (see [this Github page](https://github.com/xdrip-js/Logger) for more info) that the oref0-setup may not get correct. In particular, Logger does not currently support token-based authentication with Nightscout and so could be misconfigured if you select that option during set up.
 
    * **Lookout** - this application runs on your rig and uses the xdrip-js library to read from the G5 or G6 transmitter directly. It uses the transmitter's built-in calibration algorithm, and you can enter BG calibrations either from the receiver or from a browser on your phone or computer, when connected to a web server that Lookout manages on your rig. The Lookout web pages also allow you to view CGM, pump, and OpenAPS status. Regardless of whether you use the receiver or Lookout to enter calibrations, they will be sent to the transmitter and both devices will report the same resulting BG values (though they may take a reading or two to 'catch up' after a calibration). Depending on your phone's hotspot capabilities, you may be able to access the Lookout web server even when cellular data is not available. Lookout will read Dexcom transmitter BG data and update OpenAPS locally (via xDripAPS), so your rig will continue to loop while offline, as well as send to Nightscout when your rig is online. Since Lookout uses the official transmitter calibration algorithm, it still requires sensor restarts every 7 days, with 2-hour warmups, and cannot be used with transmitters that have reached the Dexcom expiration (105-112 days from their first use).
