Simulated RTU (Rooftop Unit) devices for VOLTTRON/AEMS testing. Exposes BACnet/IP and REST APIs to virtual HVAC equipment and a power meter.

make build
./bin/sim-rtu --config configs/default.yml

Or: make run / docker compose up

See docs/setup-guide.md for sim-rtu build/run instructions.

For full AEMS platform setup (connecting to aems-lib-fastapi with any device target), see the AEMS Platform Setup Guide.

Two driver modes for AEMS platform integration:

• NF REST (recommended) — simpler setup, no BACnet proxy needed
• Legacy BACnet — full BACnet/IP protocol, requires BACnet proxy agent

See docs/driver-switching.md for switching guide.

Helper scripts:

./scripts/switch-to-nf.sh /path/to/aems-lib-fastapi
./scripts/switch-to-bacnet.sh /path/to/aems-lib-fastapi
./scripts/start-all.sh

make build                # Build binary
make run                  # Build and run
make test                 # Unit tests with coverage
make coverage             # Coverage report
./scripts/test-integration.sh  # Full integration tests

Config files in configs/:

• default.yml — main simulator config (devices, thermal model, weather, ports)
• schneider.csv, openstat.csv, dent.csv — BACnet point registries
• aems-platform/ — AEMS config store files (README)

Bind to 0.0.0.0 in default.yml for Docker/remote access:

api:
  host: "0.0.0.0"
bacnet:
  interface: "0.0.0.0"
