First and foremost the Pulse Hub still maintains all the data tracking and notification features that our customers have come to love. Every pulse product will work together within the Pulse Grow application.

The new Pulse Hub is a modular and customizable system for monitoring all your critical parameters on one platform. It supports a wide range of up to 12 sensors per hub (with controllers in development), allowing you to scale up your output and increase yields while improving quality and consistency.

But most importantly, you choose the sensors you need.

Pulse Hub Roadmap

Built to last.
Pulse Hub is designed to withstand the extreme conditions that occur during cultivation, it uses waterproof marine-style cabling, making it easy to connect and place sensors in the harshest environments. The cabling design enables branching off of the main cable line to connect sensors (daisy-chaining), rather than requiring all individual sensor cables to lead back to the Hub. This streamlines setup, minimizes cable clutter, and simplifies sensor network management.

As mentioned, Pulse Hub offers remarkable adaptability with our cabling design. We've made a few sketches so you can get an idea of the possible setups.

Covering multiple grow spaces using a single Hub

You can use a variety of sensors in multiple grow spaces connected to a single Hub

Monitoring VWC across a large room

If you run a larger facility, you can track the VWC, soil EC, and soil temp with up to 12 sensors per Hub

What's available?

Hub (Base) + THV-1 (Air Temp, Humidity, VPD)

Hub (Base) + VWC-1 (Soil Moisture, Temp, EC)

Hub (Base) + PH-1/EC-1 (submersible pH and EC sensor)

*You're able to have up to 12 of the same or different sensors connected to a single Hub, so you can buy additional sensors later on even after you've purchased a kit*

How many T connectors do I need?

The number of T connectors required depends on your specific setup and the number of sensors you have. It's important to note that when daisy-chaining, each connector will always occupy at least one slot. The 3-Way Connector can support up to 2 sensors, while the 6-Way Connector can support up to 5 sensors, depending on how you configure it. Below, you will find example diagrams showcasing the optimal configurations for both the 3 and 6-way connectors.

  4. Select the Pulse Hub logo

  5. Press and hold the reset button for 5 seconds (Hub will start blinking blue)

  6. Press the “Search” button after light code starts

  7. Select your Hub

  8. Select your desired network & enter your password (2.4GHz only network required, if you don't see your network then it is not 2.4GHz only)

  9. If successful, you will be prompted that your device is configuring. After configuration your new device will appear on your dashboard.

Supported Sensor Setup

  1. Press the blue “+” in the bottom right

  2. Select “Pulse Hub Sensors”

  3. Plug your desired sensor into the setup port (⚙️) Press next once finished

  4. Scan the QR codes on your Hub and Sensor (Make sure the QR code stickers are not blurry and flat)

  5. You'll be prompted that the sensor was added successfully, and asked if you'd like to add another. If you wish to setup another sensor, redo same process.

Ideal Placement: The preferred is a horizontal installation into the sidewall of the rock wool block with the waveguide in a flat orientation and the insertion point between the 1/3 and 2/3 point up the sidewall. Note that with a horizontal installation into the sidewall that the reported water content will depend heavily upon the vertical position in the sidewall where the sensor is installed. If installing into the sidewall be sure to always use a consistent elevation on the sidewall for the sensor insertion. Otherwise the shift in the data will result in confused control of irrigation.

Error connecting to your WIFI? Confirm your network is 2.4GHz ONLY. If your network is dual-band or 5GHz exclusive, you will need to change your network band to 2.4GHz only via your router settings or contact your Internet Service Provider (ISP).

Device disconnected and won’t reconnect? Try restarting your router and going through the initial setup process again. If you’ve recently experienced an outage, then it’s recommended to restart your router to prevent any possible connectivity issues.

Frequently Asked Questions (FAQ)

How is the Hub different from the Pulse One & Pro?

Yes - The Hub is IP67 rated.

What type of sensors can the Hub support?

Any SDI-12 or Modbus sensors are compatible with the Hub, but they need to be officially supported. We will continue to add support for new sensor types and different vendors as needed. Send suggestions to

Can I use ___ sensor?

Maybe - We are able to support any sensor that uses Modbus or SDI-12 communication protocols, but it does require new firmware development for each sensor. Send suggestions to

Will sensors purchased elsewhere work with the Hub?

No - Sensors need to be purchased from us due the custom connector type and firmware.
