How to Prevent a Flooded Basement with Home Assistant, Z-Wave, and Zigbee

A flooded basement is one of those home disasters that can sneak up on you fast. In this video, I walk through how I use Home Assistant, a Z-Wave heavy duty smart switch, and a Zigbee leak sensor to protect my basement and well pump from potential water damage.

What’s Covered

I go over how these two devices work together through Home Assistant to automatically detect a leak and take action before things get out of hand. Whether you have a well pump, a sump pump, or just want to monitor an area prone to water intrusion, this is a simple and affordable setup that can save you a lot of headaches.

Products Used

• Aeotec Heavy Duty Smart Switch — A Z-Wave smart outlet built to handle high-amperage loads like a well pump or sump pump.
• Third Reality Leak Sensor — A Zigbee water leak sensor that alerts Home Assistant the moment it detects moisture.

Both devices integrate directly with Home Assistant, keeping everything local with no cloud required.
