Signal
An API for adding redstone-like blocks.
About this Mod
Signal is an API for adding redstone-like blocks. It abstracts the concept of 'redstone power' and handles interactions between different signal types. This makes it easier for different mods to add entirely new redstone-like systems while remaining compatible with each other.
Information for mod developers
Check out the documentation on GitHub for information on how to use the Signal API in your mods.

Signal server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.19.4). You can switch loaders with one click in the panel.
Is Signal compatible with fabric?
Signal officially supports fabric for Minecraft 1.19.4, 1.19.3, 1.19.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Signal – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Signal consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
