One operations view
for every site you run.
Greenhouses, CEA and commercial properties on the same platform. Growbud monitors the zones and equipment that drive water and energy, runs control on site, and keeps one live model of the facility. Use it for a greenhouse, an office building, a cold store, or all of them.

02 / Site operations
Greenhouses, CEA and commercial properties. Same sensors, same controls, same view.
A substrate probe and a current clamp report to the same on-site controller and show up in the same model. Run one kind of site, or both.

Every asset that costs money
Substrate, air, water and power on one bus. LoRaWAN across the site, RS-485 and Modbus in the equipment room. Readings you can verify on site.
02 · Decide
Control runs on site
Setpoints, schedules and rules run on the Growbud Edge appliance, so a valve still closes and a damper still opens when the internet is down. No subscription to keep it running.

Controller drives the equipment
Valves, pumps, dosers, vents and fans. Dampers, VFDs and shutoffs. Modbus RTU and native BACnet to the automation you already run.

- Free US and Canada shipping on orders of $200 or more
- 90-day returns, no questions asked
- 1-year limited warranty

- Shipping and returns
- Every price is published
- Sensors, controllers, and gateways are listed with their prices on this site. No quote form, no dealer, no discovery call before you can work out whether it pencils out for your operation.
- Your data is not the product
- Readings live on your site and speak Modbus RTU, native BACnet, CANopen, and a full REST API, so your history exports whenever you want in formats your other tools already read. Edge runs the loop locally and keeps running with the internet unplugged. We sell you equipment, not access to your own numbers.
- Assembled in the USA
- Dro, Vero, and the Controller are assembled in the USA. Almost all equipment is made overseas. The people who assemble your hardware are the people who answer your support email.
Integrations
Run it from Home Assistant.
Run the Controller from the Home Assistant you already have. Valves, switches, lights, fans, and levels arrive as native entities, ready for your automations. Plug an RS-485 to Ethernet adapter into the same LAN as your Home Assistant box and add the integration. No Growbud account, no cloud.

Software
Every sensor has somewhere to report.
The Growbud platform connects sensing, control, monitoring, and automation, with a free app for Growbud hardware owners. Growbud AI extends that foundation with Vision, Digital Twin, AR/VR, and AI fusion algorithms.
Free app
growbud.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.

Premium platform
In developmentgrowbud.ai
Growbud 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.
