Grandma is understimulated in assisted living, and while Mom is looking into ways to either bunk with her, or drag her back to our place, I'm exploring other options. Her apartment does have wireless internet, so we could set up some sort of telepresence or video calling device, but even something as simple as a Relay or a KC2 isn't great, because it loses power, and needs to be explained to her.

I'm thinking that we might have better luck with a Tablet or a PC solution, and I do have a Kindle Fire (5th Gen?) and an off brand Windows 10 tablet around, and I am open to a Pi Project or speciality devices, but it has to be simple enough to plug and play, and the dream would be if it could start a video chat without the receiver having to pick up, or at least as simple as a nurse being able to come in and start a call. Any suggestions?
