So the GUI is auto updating or is hosted on the internet? I don’t like the idea that I can’t use my device if something outside my network is not accessible.
Since conception, the OpenSprinkler has used Javascript files hosted on the Internet to render the UI. Version 2.x supported hosting those files on the SD card. This protects against the network going down since files are hosted locally. This also address your secondary point (discussed below) since the files can’t update unless you update them.

In general, I don’t want my tools updating with my direct approval.
I understand your point here but understand the UI is simply a front-end. The code executing your programs on the Arduino does not change unless you plug in via USB and update the firmware. Using the online method, you benefit for incremental updates and bug fixes.
