+# lockserver
+
+_better Z-Wave Lock management for Home Assistant_
+
+## Status
+
+This is a work in progress. I have some ideas of where I want it to go, but I'm mostly experimenting with my own needs.
+
+## Install
+
+To add to Home Assistant, add my hassio-addons repo by clicking the button below, then search for and install the "LockServer" addon.
+
+[![Add to Home Assistant.](https://my.home-assistant.io/badges/supervisor_add_addon_repository.svg)](https://my.home-assistant.io/redirect/supervisor_add_addon_repository/?repository_url=https%3A%2F%2Fgit.janky.solutions%2Ffinn%2Fhassio-addons)
+
+
+## Usage
+
+When you open the addon's web UI, it will show a list of Z-Wave locks. Clicking a lock shows all codes slots for that lock. Clicking edit on each slot allows changing the code, changing the name, enabling or disabling the slot, and seeing a log of recent uses of that code.
