Roller blinds from scratch

[Sylus]

Howdy, looking for a driver for roller shutters, I came across a product SUPL lif rediscount-01, I would assume such a driver at home in the blinds but I have a few questions:
1. Do you really choose this product? (It is currently on the market is something better)
2. Is there any option in the application that will close all blinds at once? because I have 12 windows and a lime tree to be all in turn
3. Will the blinds not open in the event of losing the Internet or electricity?
4. Is there any product in the form of, for example, a "tablet" that I could hang on the wall and close all the blinds at the exit? (As there is, please let me know ) https://trackeasy.fun/usps/ https://showbox.tools/
5. Can the applications be installed at the same time by e.g. 6 people and there will be no clutter ?

1. This is the SUPLA forum. The answer to this point will not be objective;) There is no better.
2. You can create a group of roller shutters. There is a limit of 10 shutters in a group, but we can change this limit for free.
3. The roller shutter will not open automatically. In the absence of internet, it can be closed / opened from the button on the wall.
4. Any iOS or Android tablet
5. You can install the application on 200 smartphones simultaneously using the same account.
