bacbus

BacBus puts a BACnet/IP and Modbus/TCP toolkit in your pocket.

Whether you're commissioning a new install, troubleshooting a rooftop unit, or verifying a controller in the field, BacBus connects you to your building network in seconds — no laptop, no proprietary gateway, no clunky
software.

DISCOVER
Scan your network and find BACnet/IP devices instantly. BacBus reads the objects other tools miss — where some scanners come back empty, BacBus pulls the full object list so you can see exactly what's on the wire.

READ
Poll live values from any point. Watch present-value, status flags, units, and object names update in real time. Read is always free.

CONTROL (Pro)
Write to points and command overrides right from your phone. Test a damper, force a setpoint, or verify a sequence on site — no truck roll back to the laptop.

MODBUS/TCP
Connect to any Modbus/TCP device, scan registers, and read or write coils and holding registers. Works with sparse and non-standard register maps.

BUILT FOR THE FIELD
• Fast, native interface that works on cellular or site Wi-Fi
• No account required to start scanning and reading
• Handles real-world devices from major manufacturers
• Designed by a controls integrator, for controls integrators

FREE TO START
Scan and read as much as you want, free. Unlock point control (writes and overrides) with a single one-time purchase — no subscription.
