easy-aso 0.1.8

Automated Supervisory Optimization (ASO) for BACnet building automation systems (BAS) and HVAC supervisory control

Easy ASO

Easy-to-follow Automated Supervisory Optimization (ASO) event-driven logic combined with an asyncio-first supervisory layer for BACnet building automation — lightweight BAS orchestration at the IoT edge with one BACnet/IP core, small agents, JSON-RPC, and room to grow without a full platform stack.

ASO made easy

Subclass EasyASO and implement on_start, on_step, and on_stop — same pattern for reads, writes, and releasing overrides:

import asyncio

from easy_aso import EasyASO


class CustomHvacAso(EasyASO):
    async def on_start(self):
        print("Custom ASO is deploying! Let's do something!")

    async def on_step(self):
        # BACnet read request
        sensor = await self.bacnet_read("192.168.0.122", "analog-input,1")

        # Custom step logic - BACnet write request
        override_valve = sensor + 5.0
        await self.bacnet_write("192.168.0.122", "analog-output,2", override_valve)

        print("Executing step actions... The system is being optimized!")
        await asyncio.sleep(60)

    async def on_stop(self):
        # Custom stop logic - BACnet release request
        await self.bacnet_write("192.168.0.122", "analog-output,2", "null")
        print("Executing stop actions... The system is released back to normal!")

Local security bootstrap

Generate local bearer tokens (diy JSON-RPC + supervisor API):

./scripts/bootstrap-secrets.sh
set -a && . ./.env.local && set +a

.\scripts\bootstrap-secrets.ps1
Get-Content .env.local | ForEach-Object { if ($_ -match '^(.*?)=(.*)$') { Set-Item -Path Env:\$($matches[1]) -Value $matches[2] } }

Then run your stack with:

• BACNET_RPC_API_KEY for outbound calls to diy-bacnet-server JSON-RPC
• SUPERVISOR_API_KEY for optional inbound auth on easy_aso.supervisor.app

Optional supervisor (Open-FDD-friendly default port):

pip install "easy-aso[platform]"
easy-aso-supervisor --host 0.0.0.0 --port 18090
