@Andrea269 , I understand about the cell phone. My late mother-in-law lived to be 93 but was only comfortable with control devices that featured physical rotating knobs/dials and actual push buttons where each button did only one action. She was very confused by cellphones, let alone smart phones.
A simple Widex remote control sounds suitable; it also avoids the vagaries of Bluetooth connections.
