LightAutomation for Hytale

What this mod does

LightAutomation is a server plugin that turns street lamps on at dusk and off at dawn. It works out the timing from the sunlight factor and only automates outdoor lights: indoor and cave lights stay as they are.

How it works

• It registers the lights players place and keeps them between restarts.
• Depending on the DefaultLogic setting, each new light is either included in the automation or not; within 10 seconds of placing it, interacting with it once flips that choice. The author admits it’s a workaround, because the API doesn’t expose the lights’ state.
• Torches aren’t turned off by default: the author figures nobody expects an outdoor torch to go out on its own.

Configuration

It’s installed in the server’s mods/ folder, which generates the config on startup: EnableLightAutomation, DefaultLogic, LoggingLevel, DawnThreshold and DuskThreshold (sunlight percentages between 0 and 1), and the ToggleableLightTypes and StaticLightTypes lists. The /lightautomation command has subcommands to reload, list and count lights, save or clear.

Update 7

Version 1.8.0 (October 12, 2026) is updated for server 0.7.0. Known issue: the API reports zero sunlight well before sunset, so the author suggests a DuskThreshold of about 0.004. No dependencies. More ideas for your server in server plugins.

How to install it

2. Copy the .jar into the server's mods folder (for a local world, into %APPDATA%\Hytale\UserData\Mods and enable it in the world settings).
3. Start the server so the config file gets generated.
