 You can choose to set up autotune as part of the oref0-setup script, and have it run nightly and adjust a new autotune profile.  It is important to realize that when autotune is enabled in your loop to run automatically, changes to your basal profile within the pump during the middle of the day will NOT cause an immediate change to the basal profile the loop is using.  The loop will continue to use your autotune-generated profile until a new one is updated just after midnight each night.  Each autotune nightly run will pull the current pump profile as its baseline for being able to make adjustments.  If you have reason to want a want a mid-day change to your basal program immediately (e.g., steroid medication started), you may have to temporarily suspend autotune to allow loop to use your pump's adjusted basal program.  
 
+If you set up multiple rigs and would like to start the autotune results on the additional rig(s) to match an earlier rig, you will need to copy these files to the new rig(s): <your_openaps_dir>/autotune/profile.json, <your_openaps_dir>/autotune/profile.pump.json, and <your_openaps_dir>/settings/autotune.json. If your new rig hasn't been looping you may also want to copy <your_openaps_dir>/settings/pumpprofile.json to get the latest pump settings from a looping rig. (You can use a command like scp to copy files between rigs, e.g,. "scp root@192.168.1.109:/root/myopenaps/autotune/profile.json profile.json.fromRigSteve".)

 As with all new and advanced features, this is a friendly reminder that this is DIY, not approved anywhere by anyone, and bears watching to see what it does with your numbers and to decide whether you want to keep running this feature over time, vs. running it as a one-off as needed to check tuning.
