Growbud connects the equipment floor to your IT systems. Sensors, meters, valves, chillers, and PLCs join over Modbus, BACnet, CANopen, and LoRaWAN. Your BMS, apps, and data tools read them back as BACnet/IP points, REST endpoints, and Home Assistant entities. Build monitoring and control for a greenhouse, an office building, a walk-in cooler, or anything you can wire up.

02 / OT to IT
Operational technology (OT) speaks Modbus, BACnet MS/TP, and LoRaWAN. IT speaks IP, REST, and BACnet/IP. The Growbud Controller and Edge Server sit between them, so the same reading from a substrate probe, a tenant meter, or a walk-in lands in your BMS, your app, and Home Assistant without a second gateway.

Connect the equipment floor
LoRaWAN and Bluetooth sensors across the site. Modbus RTU and BACnet MS/TP on RS-485, and CANopen, in the equipment room. Valves, relays, leak and flow inputs on the Controller.
02 · Build
Any reading can drive any output
Rules, schedules, and interlocks run on the Controller and the Edge Server, so a valve still closes when the internet is down. If a Modbus or CANopen device is missing, we usually add its profile in days.
03 · IT out
Hand it to the systems you run
BACnet/IP and REST on your own subnet, a Home Assistant integration, and a documented cloud API. Isolated VLANs and air-gapped sites are supported. No vendor lock-in.
Where Growbud runs today
The same sensors, Controller, and Edge Server run all three. If your site is something else, the parts are the same. Tell us what you want to connect.

Integrations
Growbud does not ask you to replace your BMS, your network, or your dashboards. Every reading and every output is available on the IT side in the form those systems expect.
Start here
Every kit uses the same parts as a full site. Add sensors, meters, and Controller outputs later without replacing anything.
Software
The Growbud platform connects sensing, control, monitoring, and automation, with a free app for Growbud hardware owners. It watches the site while you are away and tells you early when something drifts. Growbud AI extends that foundation with Vision, Digital Twin, AR/VR, and AI fusion algorithms.
Free app
Pair a single sensor, review live readings, and add gateways and controllers when the site needs continuous monitoring or automation. Monitor sensors, configure alerts, and analyze trends from any device. Free for all Growbud hardware owners, on mobile and web.
Run the hardware from Home Assistant, join the sensors to your own LoRaWAN network, and pull Growbud data into third-party applications through a documented REST API. No vendor lock-in.
Available on mobile & web
Premium platform
In developmentGrowbud AI extends the Growbud platform with Vision, Digital Twin, AR/VR, and AI fusion algorithms. Connect scheduled imagery to sensor readings and equipment actions in a live spatial model you can explore on screen or in AR/VR.
Greenhouses, CEA and commercial properties on the same platform. Connect offices, warehouses and post-harvest storage, or greenhouses and controlled-environment agriculture.
In active development. Run it on your own hardware with data kept on site, or choose managed cloud hosting. Your data is not used to train AI models unless you explicitly agree.
