## Questions & Answers

**Q: So these sensors are only motion based? 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.
