How to get a replacement for a broken sensor

How do I get a replacement for a broken sensor. I have one window/door sensor that eats trough a whole battery in just a couple of days.

ps. Why is it that you can only call or post a topic here; no email nor live chat?

Hi @quintant. To get a replacement, you’ll have to contact our support team and run through a few short diagnostics to verify it functionality. 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.
