Mobile Networks: IoT Addon — 0.0.1 Alpha

First community testing build for Minecraft 1.21.1 and Mobile Networks 4.0.1.

Added

• IoT phone app: browse your devices and check their names, locations, signal and activity before opening their individual screens.
• Camera: live remote viewing, floor/wall/ceiling mounting and screwdriver-controlled angles. Uses the client's render distance up to 32 chunks, loads remote terrain and supports cross-dimension viewing when valid coverage is available at both ends.
• Miner: mining drone with Tunnel, Level and Mine modes, a 27-slot inventory, filters, return-home controls and physical delivery to a chest.
• Farmer: soil preparation, farmland repair, planting, harvesting and replanting for wheat, carrots, potatoes and beetroot, with supply and delivery chests.
• Animal Caretaker: automated feeding and breeding for cows, sheep, pigs and chickens, with configurable population limits.
• Storage Hub: combined chest inventory through IoT cables, item quantities, name/mod/tag search and normal cursor-based withdrawal/deposit.
• Storage Connector: links a separate cabled chest network to a main hub through valid cellular service.
• Item Exporter: maintains configured item quantities in an attached chest. Empty filters export nothing.
• Item Importer: imports matching items from an attached chest. Empty filters import all items; quantities are not configurable.
• Network Analyzer: handheld coverage map for the network selected on the player's phone.
• Guided area and chest selection using the original Mobile Networks screwdriver.
• Player-owned devices with names unique within each player's device list.

Behavior and compatibility

• Devices inherit the owner's phone operator and plan, including automatic operator changes.
• Remote access requires valid service and local signal. Suspended plans block connectivity; autonomous machines can continue existing tasks without remote control.
• Updated signal selection, plan limits, signal bars and underwater attenuation for Mobile Networks 4.0.1.
• Farmer and Animal Caretaker remain entities while active or waiting; Stop requests a safe return to block form.
• Machines move one block at a time with animated turns and movement.
• Survival and multiplayer support without requiring OP. Camera viewing keeps the player's physical position unchanged.

Fixes

• Fixed the Farmer becoming stuck when a crop grows in the block it occupies. It can harvest and replant that crop without moving away.
• Fixed missing or incorrect Farmer and Animal Caretaker models in camera feeds while they are entities.
• Improved camera opening by reducing synchronous terrain preparation and sharing neither the player's terrain cache nor its rendering workers.
• Improved Farmer handling of snow, grass, irrigation channels, farmland damage and replanting at high random tick speeds.

Requirements

• Minecraft Java Edition: 1.21.1.
• Java: 21.
• Loader: NeoForge 21.1.229 or later.
• Required base mod: exactly Mobile Networks 4.0.1, using the matching JAR.
• Simple Voice Chat: 1.21.1-2.6.22, used with the base mod.
• Install the same addon build and compatible dependencies on both client and server.

Testing notes

This is an early Alpha intended for community testing. Camera FPS and terrain loading depend on client hardware, connection and server performance. Farmer and Animal Caretaker routes require accessible terrain at their placement height.

Validation included 24 unit tests, 83 server GameTests and in-game camera tests at 1920×1080 with GUI Scale Auto, 12/32 chunks, repeated reopening and resource reloads. Natural crop growth in the Farmer's occupied block was tested with randomTickSpeed 2000.

Please include reproduction steps, mod versions and logs when reporting a bug. For camera or movement issues, include a short video.
