Upgrading Old Roller Blinds – Any Good Motor Kits?

Hi everyone, I have quite old roller blinds in the living room and bedroom. They still work manually but I’m really tired of pulling cords every morning. I want to make them motorized without buying completely new shades. Has anyone tried any retrofit kits recently? Looking for something simple, not too expensive, that can connect to smart home. Would love to control them with phone or voice. Any recommendations or warnings? Thanks!
