Growlink LINKS HUB Communication Hub Controller — 8-Port 24VDC Ethernet or WiFi

The Central Communication Point for Your Growlink LINKS Devices

The Growlink LINKS HUB is the backbone of a LINKS-based automation system, serving as the central point that connects and coordinates sensors, controllers, and other automation modules through one Growlink OS interface. With 8 ports and dual-mode connectivity via Ethernet or Wi-Fi, it brings environmental data and device control together for real-time management across a grow operation.

Running on 24VDC at up to 1A, the LINKS HUB scales from a single-room grow to a large multi-zone commercial facility, either as a standalone controller or as one of several hubs deployed across a larger site.

Key Features & Benefits

• 8-Port Connectivity: Supports up to 8 simultaneous LINKS device connections in a single grow zone or room.
• Ethernet and Wi-Fi Support: Flexible dual-mode connectivity for wired or wireless facility layouts.
• 24VDC / 1A Operation: Low-voltage power delivery built for continuous cultivation-environment operation.
• Universal LINKS Compatibility: Integrates ClimaLINK, TerraLINK, LightLINK, RelayLINK, QuadLINK, and more.
• Scalable Architecture: Additional HUBs can be deployed across rooms, all managed within the same Growlink OS account.

Who Should Use This

Any grower building out a Growlink LINKS automation system needs at least one LINKS HUB, and it is especially valuable in commercial facilities where centralized, remote management of environmental controls across multiple zones is required.

About Growlink

Growlink's LINKS hardware line, developed since the company's founding in 2015, is built to serve as the communication backbone of a cultivation facility's automation network.

Frequently Asked Questions

How many LINKS devices can connect to one HUB?

The LINKS HUB has 8 ports, supporting up to 8 simultaneous device connections. Operations needing more connections in a single space can deploy multiple HUBs managed within the same Growlink OS account.

Does the HUB require a wired Ethernet connection?

No, the LINKS HUB supports both Ethernet and Wi-Fi connectivity, so you can choose wired or wireless infrastructure based on your facility layout. Wired Ethernet is generally the more reliable option in facilities with heavy electromagnetic interference from HVAC or lighting equipment.

Which Growlink LINKS devices are compatible with the HUB?

The HUB is compatible with the full range of Growlink LINKS modules, including ClimaLINK, CanopyLINK, TerraLINK, LightLINK, RelayLINK, QuadLINK, HVACLINK, and TankLINK systems. Any combination of these devices can connect to the same HUB, up to its 8-port capacity.

Can I manage multiple HUBs from a single Growlink account?

Yes, multiple LINKS HUBs across different rooms or zones can connect to the same Growlink OS account, giving you one centralized dashboard for the whole facility. This scales cleanly as a cultivation operation adds rooms, since each new HUB simply joins the existing account rather than requiring a separate login.
