GrowMore Hub Universal Controller

Product Description

The GrowMore Hub Universal Controller is the first open-source networked 0-10v controller for the "Grower", agriculture, HVAC, and lighting applications. The GrowMore Hub is an ESP32-S3 based controller for temperature and humidity monitoring and control of 0-10v Electronically Commutated (EC) in-line fans, grow lights, and other related devices. This HUB features the powerful ESP32-S3 processor from Expressif, with integrated WiFi and Bluetooth functionality (BR/EDR/BLE).

Don’t be tied to one fan or lighting manufacturer’s devices or limited controller solutions, and especially not their non-networked or APP based controllers. The GrowMore Hub is versatile, flexible, and software customizable when required in an easy programming environment.

Interfaces

The GrowMore Hub has four flexible individually controlled 0-10V ports, outputting either a 0-10v PWM digital signal or 0-10v analog signals, supporting a wide range of devices from numerous manufacturers that support this common standard. It has the ability to set the PWM or analog signal in 65536 steps unlike the 5 or 6 steps other controllers have. It also has the flexibility to output any maximum voltage level from 5v to 14v. It also monitors fan speed or other device outputs related to each of those device ports.

The GrowMore ports can also be used as DACs outputting 0.15 millivolt resolution at up to 20kHz.

It allows monitoring of temperature, humidity, and even pressure from multiple sensors, zone located, to allow you the flexibility for accurate control of temperature, humidity, and lighting condition for optimal plant growth.

Open Source, Open Protocols

Whether you are using the GrowMore Hub for a small grow tent, grow room, greenhouse, or many in an entire facility, the GrowMore Hub is the perfect solution for you. Moreover, since it implements open protocols for control and monitoring, whether you are using one or one hundred, you can control and monitor your installation through one interface.

Besides each Hub having its own webserver though WiFi, accessible from any browser, it supports the ubiquitous MQTT communications protocol and integrates into popular automation software like Home Assistant, Node-Red, ThingsBoard, and many others as well as popular voice assistant interfaces like Amazon Alexa and Google Home.

Versions

The GrowMore Hub comes in two versions, first the GrowMore Display Hub with a 2.4” LCD display and touchscreen, that allows device local monitoring and control through the touchscreen, and the second a headless GrowMore Standard Hub for remote control configurations. Moreover, you will be able to control and monitor any headless GrowMore Standard Hub, from one GrowMore Display Hub as well as the locally attached devices and sensors (currently in Beta).

Software

The GrowMore Hub allows manual setting of fan speeds or lighting intensity setting though its LCD display, or remotely via the network with the webserver interface, HTTP API, MQTT or HA API. You can also access temperature/humidity/pressure (depending on attached sensors) reading through the same interfaces, allowing easy integration into your own control system and algorithms.

Or in the alternative set one or all of the GrowMore Hub’s ports to “Auto Mode”, in which it will use its built-in PID algorithms to maintain a target temperature or humidity and automatically turn on, turn off, or set a devices levels based on a programmed schedule. Over-temperature or under-temperature alarms are also available as well as performance monitoring and detection of failed devices.

Cases

Both versions of the GrowMore Hub come in custom cases that can be attached to surfaces with two M3 screws or by its magnet base to ferrous metal surfaces.

Highly Customizable

The GrowMore Hub utilizes the ESPhome system software which provides an open-source environment and that allows sophisticated customers complete control over the operation of the device and integration into environments we may not currently support. The graphical user interface is programmed in LVGL for easy modifications.

For this, the GrowMore Hub has a USB-C interface for downloading firmware and power during development. Or if you are doing small modifications or updates to firmware, use its remote Over-the-Air update feature.

Supported Devices

The GrowMore Hub uses four (4) 3.5mm TRRS connectors to attach devices under control (at least one of the devices must provide power like a TerraBloom EC in-line fan). It supports any fan, lighting, or other device that uses the 0-10v control standard either PWM or analog controlled, such as the TerraBloom ECMF Series and the AC Infinity UIC Platform Series devices such as the Cloudline fan series, humidifiers, heaters, and grow lights (UIC adaptor cable require).

For environmental sensor inputs the GrowMore Hub has both a One-Wire port and three I2C ports which interface to a variety of One-Wire and I2C sensors.

The One-Wire port allows for a virtually unlimited (limit by total cable length) number of temperature sensors. We provide those sensors here that are factory calibrated with your controller. We also can provide sensor multiplier cables and sensor extension cables to facilitate their remote placement.
