A law was passed two years ago to allow certain types of OTC hearing aids. From the FDA’s website…
To increase the public’s access to hearing aids and improve hearing, the FDA established a new category of over-the-counter (OTC) hearing aids for adults 18 years of age and older with perceived mild to moderate hearing loss that went into effect on October 17, 2022.
Glad you got it to work eventually. I never liked smart bulbs. I use smart switches instead (Meross works really well with HomeKit). Set the lamp’s on/off switch to the on position and plug it into the smart switch. The smart switch can be connected to HomeKit anywhere in the house. You can set it up in the kitchen, then move it to your daughter’s room.
