Hi @shirleymac Sounds like you have been getting some good suggestions here! In our case we, too, used a simple baby monitor for my wife. I got one at a garage sale for $5.00. I also put an old fashioned shop bell on the bedroom door. If the door was opened it jangled and the noise was enough to wake me, especially once I got attuned to it.

Now I have gone a bit more high tech and spent a bit more and bought a Nest camera. It sends an alert to my phone each time it 'sees' anything move. It also has a microphone so I can listen or talk, too. No monitoring expense, just their free app once you buy any Nest product. I went with Nest because I had installed one of their remote thermostats.

Just my ideas of what worked and works for us.

Strength, courage, and peace!
