For growers · 01
Agriculture
Root-zone sensing and closed-loop irrigation for indoor rooms, greenhouses, and outdoor blocks, with canopy temperature, humidity, VPD, and CO2 on the same loop, so a vent opens or a pulse waits on what the plant is in. The same climate map runs the spaces after harvest: drying rooms, barrel and cask rooms, curing and storage. Irrigate to what the substrate actually holds instead of to the calendar, and see the gradients your thermostat hides. Readings you can check by hand, and control that keeps running when the network doesn't.
The loop
Sense it. Decide it. Water it.
A closed loop that lives on your site, from probe to pump, and keeps running when the internet doesn't.
- Readings you can check
- Moisture, nutrient strength (EC), and temperature you can ground-truth yourself against pot weight, in your own medium. Built for salty hydro media and dry field soils, not only open-field row crops.
- Control that lives on-site
- Edge Server makes control decisions on-site. When the network drops, irrigation and automation keep running. The operation never needed a login.
- From source to valve
- One system from probe to pump. Sense, decide, and move water on the same platform, or hook into the irrigation, feeding, and building gear you already own.

Commercial buildings
The same Controller, pointed at the machinery instead of the crop. Power, water, and air on one RS-485 bus, speaking Modbus RTU and native BACnet to the building automation you already run. Find the pump that never shuts off, the compressor short-cycling all night, and the line that has been leaking since Friday. Those three quietly run up both bills.
- Indoor air, room by room
- Temperature, humidity, and CO2 in every occupied room, mechanical space, and cold room, on long-range wireless sensors that place anywhere and run years on a battery. Readings land in the BMS as ordinary points, so ventilation responds to conditions instead of a schedule, and a room short on fresh air shows up before anyone complains.
- Submetering
- kWh per tenant, per circuit, per machine. Modbus energy meters on the panel and the Power Meter Outlet on anything with a cord, metering at ±0.5% and switching over long-range wireless. Current is how each machine reports its own condition, so a compressor short-cycling or a motor pulling harder shows up before it fails.
- Leak detection and verified shutoff
- Leak sensors in boiler rooms, mechanical rooms, and under water heaters. The Controller closes the supply valve, confirms flow actually reached zero, and alarms if it didn't, so a valve that fails to seat is something you find out about before the flood.
- Automation
- When this, do that. Valve and relay outputs on the Controller, the Power Meter Outlet on the radio, and any reading in the system able to drive either. Sixteen schedules and every interlock run on site, so the building keeps operating through an internet outage. Bring us the sequence and we will say what it takes.
- 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 built to order and assembled in the USA. Almost all grow equipment is made overseas; ours is put together, tested, and shipped from here. The people who assemble your hardware are the people who answer your support email.
