It still works via live mode or a custom scene on the latest Mobius app version - Im not in front of my tank to create a video as a demonstration but i currently switch my pumps off (4 MP40's on one tank & 1 on another) by clicking one button - A custom scene i created in Mobius that sits on the home screen.
You need to create a new scene via the Edit button next to the word SCENES on the landing screen (home screen of Mobius). Select EDIT - (+) - then CUSTOM, not FEED MODE, we want them off, not just low.
Set the time duration to 24 hours, or any long length of time (well be turning them on and off on the click of a button anyway regardless). You then select your pumps as a group inside this custom scene and select feed mode to the off postion. Once this is set up correctly you will have a custom SCENE on the home screen of the app that on one press can shut down all of your pumps together.
This video is a poor example as it doesnt show exactly what needs choosing, the best i can do away from my tank but towards the end it shows a custom scene setting for the Vortechs - Do the same but instead of CONSTANT mode that they choose - scroll across to feed mode and pull below the bottom of the bar.
Its not very well documentated and this is the problem with Mobius in my opinion. Its capable of very good things, but most are a little iffy to experiment with it to find out what it can do and rightly so on living tanks to be fair.
So sorry, you are correct. The mistake I made is NOT swiping over to the FEED profile when setting up the new scene. It defaulted to "CONSTANT SPEED" and I was using that. Dumb mistake. Thanks for sticking with me. Hopefully this will help others
To summarize, if you want to stop pumps on demand in Mobius, do the following:
1) From HOME page, click "EDIT" button
2) From Scenes page, click "+" button and select "Custom" scene
3) A new Custom scene is created with a default name at bottom of list, select it to edit it.
4) In the Edit page for this new scene select "VORTECH".
5) Use displayed scroll bar to change speed . WARNING: Pump profile will default to "Constant Speed" option. Swipe left until you see "Feed"
6) Using the slide bar, slide down on the slide bar past the bottom. A countdown will begin. Continue to hold until prompted with warning. Press "Okay", Press "Done"
7) Press Home icon and you are back to home page and have a new scene. If you don't see it then you must have more than 6 scenes created already. Swipe left to see next page of scenes
It seems to work. Of course, a built-in dedicated STOP button would seem to make more sense, but what do I know, I only design software and GUI's for a living LOL
