+[HomeSeer](https://homeseer.com/) is a member of the Works with Home Assistant partner program for their Z-Wave products. Despite offering their own Home Automation software HomeSeer is committed to making sure their products are up-to-date and ready to use in Home Assistant.
+
+HomeSeer products are all Z-Wave Plus certified. Their wall switches and dimmers offer convenient additional status LEDs that can signal events happening in your home and double-tap actions for triggering automations and scenes. Their water valves will stop the water flow when leaks are detected and notify you.
+
+HomeSeer Z-Wave devices work locally and integrate seamlessly with the Z-Wave integration in Home Assistant (Z-Wave stick required). As all connectivity is happening locally, status updates and controlling your devices happen instantly in Home Assistant.
+
+### Firmware updates
+
+HomeSeer periodically releases new firmware with additional features and functionality which can be sent to devices via an encrypted OTA (Over-The-Air) update process. In Home Assistant, you can navigate to your device page and use the Update Device Firmware option to upload the firmware from HomeSeer for your device.
