homecore-plugin-example

Example WASM plugin for the HOMECORE plugin system (ADR-128 P2).

Demonstrates the complete ADR-128 host ABI round-trip:

• plugin_setup — subscribes to sensor.test_temp state changes
• plugin_handle_state_changed — sets binary_sensor.test_alert to on when temp > 25, off when temp < 20

Build

# Ensure the wasm32 target is installed (once)
rustup target add wasm32-unknown-unknown

# Build the example plugin (from this directory)
cargo build --target wasm32-unknown-unknown --release -p homecore-plugin-example

Output: target/wasm32-unknown-unknown/release/homecore_plugin_example.wasm

Run the integration test

# From v2/
cargo test -p homecore-plugins --features wasmtime
