I can see why they don't make a bed presence sensor like this for sale as the sensor strips are so thin and fragile feeling and getting them setup appropriately will be different for each mattress, but I think this is going to be my favorite sensor yet. I've been able to automate a lot of things that had been time based previously to occur only when we go to bed or wake up now like our bedroom shades opening 5 minutes after we get up (so they don't open in the middle of the night if we both get up at the same time to go to the bathroom) rather than at a certain time on weekdays and another on weekends. Since we don't always get up at the same time it's nice to not have the sun suddenly hitting our faces at a certain time in the morning. I still have them opening on time when the mode is away though so it still looks like we're home.
It also arms to night mode, turns off all the lights, verifies the doors are locked and the garage door is closed, and others when we go to bed and it triggers Alexa to tell the forecast in the morning using a virtual motion device and Alexa routine. I also had to take into consideration that we are sleeping when we're both in bed and both home or when one of us is bed if the other is not present (traveling, not that that's happening with Covid but maybe next year).
