Two Ways to Add Capability
Option 1: Buy Pre‑Configured (Recommended)
Get BluNODE with expansion boards already installed—factory tested and ready to deploy.
BluNODE CL — Includes CL board pre‑installed for 4‑20mA analog sensors
BluNODE DP — Includes DP board pre‑installed with 4× differential pressure sensors
See BluNODE CL | See BluNODE DP
Option 2: Add Expansion Boards Later
Start with BluNODE base and add expansion boards when you need them—customer‑installed.
CL Expansion Board — Add 4‑20mA analog capability
DP Expansion Board — Add differential pressure sensors
Why Buy Pre‑Configured?
Same total price, pre‑installed and factory tested, no installation required, ready to deploy immediately.
Need Both Capabilities?
Combine any BluNODE model with expansion boards:
BluNODE CL + DP Board (analog + differential pressure)
BluNODE DP + CL Board (differential pressure + analog)
Talk to Our Team for help configuring your ideal setup.
Flexible. Scalable. Expandable.
Standalone Operation Deploy BluNODE as an independent data logger for targeted monitoring—zone‑level systems, individual equipment, or temporary studies.
Networked with BluCORE Connect multiple BluNODE devices to BluCORE for centralized data aggregation, analysis, and facility‑wide intelligence.
Integrated with BluPULSE Add BluPULSE pulse readers to extend your pulse metering capability beyond the four built‑in inputs.
Mixed Deployment Combine BluNODE base units with BluNODE CL and BluNODE DP devices across your facility to optimize costs and capabilities.

FAQs
What sensors does BluNODE support out of the box?
1
BluNODE includes 20 temperature inputs, 4 pulse inputs, 4 current transformer inputs, and 40 Modbus sensor connections—covering most building monitoring applications without expansion boards.
Can I add expansion boards later?
2
Yes! You can add the CL board (4‑20mA analog) or DP board (differential pressure) anytime—at purchase or in the field. Boards are customer‑installed with detailed instructions provided.
Can BluNODE operate without BluCORE?
5
Yes. BluNODE functions as a standalone data logger with local storage and processing. BluCORE integration is optional for centralized monitoring.
Can I move BluNODE between locations?
6
Absolutely. BluNODE's compact design and flexible mounting options make it ideal for temporary installations or redeployment as monitoring needs change.
Does BluNODE require an internet connection?
7
No. BluNODE operates independently with local data storage. Connectivity (Wi‑Fi, cellular, LoRaWAN) is optional for remote access and data transmission.
We offer three support plans—The Starter, The Pro Setup, and The Expert Edge—covering everything from initial setup to ongoing optimization.
What support is available after purchase?
8
Most applications work fine with the base BluNODE. Add CL if you need industrial 4‑20mA sensors (pressure transducers, flow meters). Add DP if you need HVAC differential pressure monitoring.
Do I need expansion boards?
3
Can I add both CL and DP boards?
4
Yes! BluNODE supports both expansion boards simultaneously for complete monitoring capability.
