I’ve got this setup: Two of those flat contact sensors that are designed to go under a mat, connected to an ESP32 running ESP Home. Some people use leak sensors with screw terminals instead of the ESP32 and attach the contact sensor that way. My use case is that we’ve got cats and motion sensors, so when everyone is in bed, the lights don’t react to the motion. Also, alarm system goes into night mode, any reminders before going to bed also fire. There are a set of rules about whether the doorbell can be heard in the bedroom, and also the light comes on in the night if someone gets up.
