Mineqtt
by OddHero
Mineqtt lets Minecraft talk to IoT devices over the MQTT protocol, so a lever or redstone signal can switch real-world hardware such as smart lights.
What it does
The mod connects a Minecraft world to an MQTT broker, with username and password authentication. Topics for senders and receivers are configured through a GUI, and redstone signal strength can be sent and received. Redstone contraptions can control physical devices, display sensor values, or pass signals wirelessly between worlds that share the same broker, including single-player worlds and online servers.
Required dependencies are Architectury API and Fabric API. Flan is an optional dependency. Mineqtt runs on client and server, so both the server and every player need it. It is released under the GNU Lesser General Public License v3.0 or later, and its source code and issue tracker are public. Files are published for Fabric and NeoForge, for 1.21.8 and 26.2, with version 0.8.0 as the latest build for 26.2.
Key features
MQTT broker connection
Connects to an MQTT broker with a username and password, so devices on the network can exchange messages with the game.
Topic configuration GUI
Senders and receivers are set up per topic through an in-game screen, without editing files by hand.
Redstone signal bridging
Redstone signal strength is sent to and received from topics, letting circuits drive or read external devices.
Portable topic debugger
A handheld Cyberdeck item subscribes to and publishes topics, for testing a setup in the field.

Use cases
Smart lighting
A lever or circuit in the game switches smart lights on the real network.
Wireless redstone across servers
Several servers connected to the same broker can pass redstone signals between them.
Who it’s for: Players who run automation with real hardware, and server owners who want an MQTT link between their world and an external network.
How it compares
Wireless Redstone Signals is a Fabric mod for 1.21.4 – 26.3, open source under the MIT License, that works on client and server. Simple Wireless Redstone is Fabric-only for 1.21.10 – 1.21.11, under a Creative Commons Attribution Non Commercial 4.0 license and not open source. Simple Redstone Remote is NeoForge-only for 26.1.2, client-side only and under All rights reserved. Mineqtt is different from each in that it bridges to MQTT devices instead of only sending signals between Minecraft blocks.
