Hi there, @ihor! You’ve reached the Ring Community, a public neighbor to neighbor forum. While there are Community team members and neighbors here to provide suggestions or guidance, our support teams do not monitor this platform.
Check out our Community post, for helpful tips on the the Retrofit Alarm Kit.
To reach our support team, please give our support team a call at one of the numbers available here. 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 to see how to contact support. I hope this helps!
