I mean, the network instructions should really not be able to do anything the buttons on the front couldn’t, but I see your point all the same.

They have a failsafe via a pressure relief, 2 of them, so I wouldn’t worry too much.

Even as a sighted cook, I do rely on the noise a pressure cooker makes when relieving pressure at the red line. There is usually a visual pressure indicator, but on most models it is rather "binary" anyways, either the knob is out or in.

Agreed for a gas-heated pressure cooker, electric would be fine.
