    Re-Did my home security with these all over. Easy to install easy to use and easy to access the battery when they need replacing in 3-4 years. Definitely worth it if you use ring/Alexa for the rest of your home.

    They work with gen1. We bought the alarm system quite awhile back. We needed to add sensors. I don't have the alarm monitored. We need a text alert not an email.
