Turning a garage roller shutter smart

We have a simple roller shutter for our back yard. It uses a fob with an up button to raise it, and a down button to lower it. It has a sensor built in already so it knows when it reaches the floor and stops.

Any advice for a device that could make this “smart.” I tried a “meross” smart garage door opener - but I found out it requires an additional sensor to be installed - I do not want to do this as it will just add in too many elements. I essentially want just a smart garage fob, that I can activate via my phone to function in the same way as the regular fobs do.

TIA
