Oh Wow! This just made my cheap home automation even cheaper.. This is my rig: a 2x $30 pack of 5 RF outlets and a $50 Hook that converts these outlets into smart outlets, with a $49 echo dot now i can control all my lamps and appliances in my home all under $200 with my Voice and my phone.. Loving it!
Photographs and portraits professionally enhanced and framed. You may take them for granted but old people don't like looking at pictures on phones.
I blew up a black and white picture of my parents when they just married and coupled it with a more recent image of them before my father died. I also enhanced and enlarged some portraits of my father in his navy uniform, put it in a nice frame and my mother goes nuts for that stuff.
On the more practical side, my mother is physically disabled so I hooked up all her lights and her portable heater to a cheap wireless remote control system so she doesn't have to hunt around and end up stumbling in the dark.
It's also not too late to get them a tablet. My mom always scoffed at people who looked at their phones all the time and since I got her a big screen tablet with an adjustable stand to hold it, she spends hours on it.
