Hi @Murphy0Wesley. The Retrofit Kit is not compatible with any wireless sensors, as it's designed to allow you to use existing hardwired alarm sensors with the Ring Alarm system. You can find all of the information we have on the Retrofit Kit in our Help Center Article [here](https://support.ring.com/hc/en-us/articles/360032456492-Welcome-to-the-Ring-Retrofit-Alarm-Kit), which should answer any questions you have. You can also reach out to our support team at one of the numbers available [here](https://support.ring.com/hc/en-us/articles/213608406) for any further questions. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 [here](https://support.ring.com/hc/en-gb/articles/360041597471) to see how to contact support. :)
