Instructions suggest setting up port forwarding for remote access, but no further security details are listed.
If I use port forwarding and login from the a web browser or the iOS app, is the login password encrypted?
Is https used for security or is port forwarding just exposing the regular http/webui to the internet?
My initial impression is that I should not use port forwarding and just use a secure VPN to connect to the local lan remotely instead.
I have also found instructions on reverse proxy ( http://rayshobby.net/mediawiki/index.php?title=Secure_Remote_Access ) but this seems to only support the PI or Beagle versions of Open Sprinkler, not the commercial version.
