I am a professional software developer. I also play with ESP32, Raspberry PI & the like.
I have an elderly relative, who is too far away for me to visit, and it is also difficult for family who are nearer.
I am thinking of some tele-monitoring.
I can imagine making a ring-doorbell clime with an 2 and FOSS face recognition Software for $15, so that they don't have to go to the door to see who is there.
there are FitBit clones, also about $15, which can measure heart rate (sleep, maybe temperature), and also let me know if they are mobile.
In short, I would like to find as many affordably devices as I can to remotely me=monitor a family member's health .... maybe some way of checking that pills are taken, even that he fridge or food cupboard door is opened.
However, most S.E sited have a "closed for being too broad" option. Is there any way to formulate such a Question to be on topic? The problem is that if I knew exactly what devices I wanted, then I could ask a bunch of separate questions, but I really want input for others to tell me what I haven't even considered yet.
