Someone can literally smash out a window and climb through unless there is a glass break sensor within 20ft?** A: Rather than buy glass break sensors for all of my windows, I have window sensors on all the windows and a motion detection sensor in each room. I have rooms with four and five windows. It saves money and does the same job. **Q: if I put it in my car a connect it then drive off and return within range, will it automatically reconnect to the home base?** A: You can disconnect and reconnect it by using the keypad. **Q: Will this work with only a wyze lightbulb? i need it to turn on the light automatically when i open my door. i do not have a base... only a lightbulb** A: No. I use sensor lights **Q: are these compatible with nest security systems** A: This is a simple magnetic switch that communicates with the Simplisafe base station. Not 100% sure but I suspect it is proprietary to the Simplisafe system. You might want to contact Nest with this question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect replacement *by M***L on 20 April 2026* ### ⭐⭐⭐⭐⭐ Works very well *by T***E on 1 May 2026* ### ⭐⭐⭐⭐⭐ A little bit safer! *by K***S on 18 March 2026* ## Frequently Bought Together - SimpliSafe Entry Sensor (Pack of 4) - Window and Door Protection - Compatible with The SimpliSafe Home Security System - Latest Gen - SimpliSafe Glassbreak Sensor - 20ft.
