What if I don't have the button "set" on my controller?

Is there a WIFI model which can safely replace the FUT038S ?

I have a problem with this controller, I connected everything, paired it with the remote control, with the application on my phone and everything works very well. However, after several power cycles, off/on, the controller itself goes into pairing mode and the LEDs flash red. I do not turn it on and off consecutively, but even after several days, but the controller goes into pairing mode and flashes red, how to solve this problem? At this point, the device is disqualified by the fact that when you turn it on, the LEDs flash red, it makes no sense.

Can i connect led strip light ? And how many feet can i connect with this controller?

I would like to attach the miboxer under a stretch ceiling, which means I can't get to it later, for example to press the button. If I have learned the part on the WiFi and later change the WiFi password on the router, do I have to turn to the miboxer and reset the device with the button? or is that changed via the app? would be stupid if I had to press the button, since I won't be able to get to it anymore and you change the wifi password from time to time... (I also have fut089 remote control for 7 Miboxers) thanks for your great help in advance

This model is compatible with fut 007 for drive CCT strips?
