By default, the latest Psensor doesn’t start automatically when you login (unless you’ve upgraded from an older version). If you do want it to run on startup, in its Preferences (not Sensor Preferences!), click on the Startup tab and then enable “Launch on session startup“. If you don’t want the Psensor window to be displayed on startup (for instance, you only want the indicator to start automatically – you can manually open the Psensor window later on), also enable “Hide window on startup“.
