Having trouble explaining how to use the smart control component to our Grandmother

She was confused with the touchscreen & she didn’t assume what all those buttons were supposed to be.

I don’t assume what our cousin was thinking about getting our Grandmother a pricey touchscreen control component for her birthday. She still had an old dial control component on the wall & our cousin was saying she would appreciate the lower energy bills & all… Of course, our cousin didn’t offer to help install the thing. My Grandmother doesn’t like trying to mess with modern technology. She refuses to use smart PCs, so I wondered how our cousin thought she would use a smart control unit. I was the a single who ended up helping her install the thing. While I thought she would never want to use the modern control unit, I had to disclose that it would save her cash on the energy bills & I tried to explain that to her. She said if I wanted to install it, I could. So I did & I showed her how to work the thing. She was confused with the touchscreen & she didn’t assume what all those buttons were supposed to be. I wished our cousin would have gotten her something more practical like a nest control component that works something like a dial control unit. At least with something like that our Grandmother wouldn’t be so confused. I ended up just telling our Grandmother to let myself and others access the control component with our PC & I’d adjust the temperature control settings to what she wanted. She was even more confused then because she didn’t assume how I could adjust the temperature control settings with a telephone! She was acting like I was losing our mind, & I realized it was impossible to explain this technology to her.
