The Aero platform

One platform. Every layer of the building.

Aero is a complete building automation stack, with AeroNode at the edge, AeroServer on premises, AeroConnect in the cloud and AeroView everywhere, built on one shared core so every layer speaks the same language.

  • Edge-first
  • Outbound-only mTLS
  • BACnet + Metasys N2
  • HTML5 AeroView
  • No point licensing

Architecture

The edge does the work. Everything else adds visibility.

AeroNodes run the building on their own. Supervisors and the cloud connect through a stream that each node opens itself, so the building never has to let anything in.

  1. 1

    Operators

    Any browser, on site or remote. AeroView is pure HTML5, with no Java and no thick client.

  2. 2

    AeroServer · AeroConnect

    On-premises supervisor and optional cloud relay for remote access.

  3. 3

    Outbound mTLS

    Every node dials out over one mutual-TLS stream. No inbound firewall rules.

  4. 4

    AeroNode

    Supervisory controllers that run logic, schedules, trends and alarms locally.

  5. 5

    Field buses

    BACnet MS/TP, BACnet/IP and Metasys N2 devices, including AeroStat thermostats.

AeroView

One interface, in any browser.

AeroView is the HTML5 application every AeroNode serves over HTTPS, and the same interface AeroServer uses for the whole station. There's no Java, no thick client and no engineering-workstation license.

Capabilities

What every AeroNode does out of the box.

No add-on modules, no feature licenses. Every capability below ships in the standard firmware.

Driver framework

Each field protocol runs as its own supervised driver process, so a misbehaving device or a hung serial port can't take down the controller. Every serial port is driver-agnostic, and new protocols arrive as signed firmware updates.

Program sheets

Drag-and-wire control logic with live values: about 40 blocks including PID, formula, delay, edge detection and alarm blocks. Package proven sequences as versioned macros and reuse them across jobs.

Schedules

Weekly schedules with date-range exceptions and a month view. Device schedules stay in sync with BACnet Schedule objects, and node schedules command points at the priority you choose.

16-level priority arrays

True BACnet command arbitration on every writable point: timed overrides, relinquish defaults, and priorities that survive a reboot. Schedules, logic and operators coexist predictably.

Trending on the edge

Interval or change-of-value logging with per-point retention, stored on the node itself. Multi-point charts and CSV export in any browser.

Alarm management

Point limit and state alarms with delays and deadbands, device-offline alarms and logic-driven alarms, with a full acknowledge/clear lifecycle that writes acknowledgements back to BACnet devices.

Dashboards & equipment graphics

Build dashboards from gauges, trends, alarm lists, setpoint adjusters and floor plans. Generate equipment graphics from 11 templates (AHU, VAV, RTU, FCU, boiler, chiller and more).

BACnet server

Publish Aero points as BACnet/IP objects so an existing front end, whether Niagara, Metasys or another BACnet workstation, can read and command them during a phased migration.

AeroNet peering

Pair nodes directly with a one-time code. Share points, and view a peer's alarms, schedules and trends with no server required.

BACnet time sync

Opt-in time synchronization for field devices, and it will not push the time if the node's own clock isn't synchronized.

Signed firmware, automatic rollback

Every firmware release is cryptographically signed and verified before it installs. If a new version fails to start, the node automatically restores the previous one.

Secure by design

Encrypted access on every node, protection against repeated failed logins, and authenticated, encrypted connections to supervisors. Nodes only dial out, so there are no inbound firewall ports to defend.

Commissioning that respects your time

A guided setup wizard, network changes that roll back automatically if you lose contact, device discovery, and point managers built for bulk work.

AeroConnect

Remote access without the VPN.

AeroConnect is HBT's cloud relay. Because every node already dials out, remote access needs no VPN appliance, no jump box and no port forwarding, just a browser.

AeroConnect is an optional subscription service. AeroNode and AeroServer work fully without it.

Per-session authorization

Every remote session is individually authorized and limited to a single node.

The node still decides

Remote sessions land on the node's own login, so its users and permissions apply unchanged.

Built for contractors

Organize nodes by company, invite team members, and grant customers access to just their own buildings.

Portfolio at a glance

See which nodes are online, when they were last seen, and their open alarms across every site.

Security

Secure by design, not by add-on.

Building systems are infrastructure. Aero's security model starts from one rule: nothing gets to reach into the building.

Outbound-only connectivity

Nodes dial out to AeroServer and AeroConnect. No inbound firewall rules, no port forwarding, no exposed controllers.

Authenticated, encrypted connections

Every connection between a node and its supervisor is mutually authenticated and encrypted with industry-standard cryptography.

Controlled enrollment

A node joins a supervisor only through a one-time enrollment step authorized by an administrator.

Signed firmware

Firmware is cryptographically signed and verified before it installs, so only genuine Aero releases run on a node.

Automatic recovery

If a new firmware version fails to start, the node restores the previous version on its own.

Encrypted access, protected logins

AeroView is served over HTTPS, with protection against repeated failed login attempts.

Protocols & drivers

Open protocols at the field level.

Every AeroNode serial port is driver-agnostic. Our goal is to support the open RS-485 and RS-232 protocols found in buildings through Aero drivers, delivered to installed controllers as signed firmware updates.

BACnet/IP

Full client: discovery, polling and COV, priority writes, foreign-device registration, device alarms and schedules.

Shipping

BACnet MS/TP

Native RS-485 trunks on every AeroNode, with a frame log for troubleshooting.

Shipping

Metasys N2

N2 Open supervision: address scan discovery, point reads, and output overrides with release.

Shipping

BACnet server

Selected points published as BACnet/IP objects, plus global schedules as BACnet Schedule objects.

Shipping

On the driver roadmap

  • Modbus RTU (RS-485) and Modbus TCP
  • RS-232 serial device drivers
  • Additional open RS-485 protocols
  • BACnet Secure Connect (BACnet/SC) transport
