Introducing Our Sonoff-Based CO2 Monitoring & Control Kit

For years, growers who wanted to automate CO2 in a grow room or tent had to accept one frustrating reality: CO2 control was expensive. Even if the rest of the room was automated, CO2 was often the missing piece. Lights, fans, extraction, irrigation, heating, humidification and dehumidification could all be automated — but proper CO2 control usually meant buying a separate controller system at a premium price.

That is exactly why this kit matters. Our Sonoff-based CO2 Monitoring & Control Kit brings true app-based CO2 automation into a price range that makes sense for hobby growers, serious home growers and commercial growers alike.

Why This Product Matters?

Until now, a dedicated CO2 monitor and controller setup has usually been one of the more expensive environmental upgrades in a grow room. A typical setup often meant paying around R4000 to R5000 for a monitor/controller, about R1200 for a regulator, and then extra for switching or automation hardware.
In real terms, many growers were looking at R5000 to R6000 or more just to automate CO2 properly.

By using the Sonoff AirGuard CO2 monitor together with a compatible Sonoff smart switch and a complete regulator setup, we are able to offer a full CO2 monitoring and control kit for only R3399. That pricing is genuinely disruptive in this category. It opens the door for many growers who have wanted CO2 automation for years but simply could not justify the cost.

Why Sonoff Changes Everything?

The real breakthrough is not just the price — it is the ecosystem. This kit is Sonoff-based, which means it is not just a standalone CO2 controller. It becomes part of a much bigger smart grow room system.

With Sonoff, your CO2 system can live inside the same control environment as the rest of your grow room. Instead of having one device for CO2, another for humidity, another for temperature, another for timing and another for switching, you can start building one connected smart system. In other words, you are not just buying a CO2 controller. You are buying into a smarter way of running the entire room.

More Than CO2: A Complete Grow Room Control Platform

One of the biggest advantages of a Sonoff-based system is that it can be expanded far beyond CO2. Using Sonoff smart switches, sensors, relays, plugs and scene automation, growers can build a grow room where multiple pieces of equipment work together intelligently.

Depending on the room and how far the grower wants to go, Sonoff can be used to control or automate extraction fans, intake fans, circulation fans, heaters, humidifiers, dehumidifiers, irrigation pumps, solenoid valves, lighting schedules, exhaust triggers, timed devices, alarms and environment-based response actions.
That means the system is not only measuring conditions — it can actively respond to them. If temperature rises too high, extraction can be triggered. If humidity climbs too high, dehumidification can switch on. If CO2 drops below target, the regulator can activate.

If conditions move out of range, push notifications can be sent to the phone. CO2 is no longer isolated. It becomes part of a bigger environmental control strategy.

A Huge Advantage Over Traditional CO2 Controllers

Traditional CO2 controllers in the grow industry are often expensive, limited and closed-off. Many only do one job: measure CO2 and turn a regulator on or off. That may work, but it does not give the grower much flexibility.

By contrast, this Sonoff-based system offers app-based monitoring, history tracking, push alerts, temperature and humidity monitoring, scene-based automation and easy expansion with other Sonoff devices. It is not just cheaper — it is smarter.

App-Based Control Makes a Big Difference

Using the eWeLink app, growers can view live readings, connect devices, create automation scenes and manage the system from their phone. That means you can check CO2 levels remotely, view temperature and humidity at the same time, receive alerts when values move outside target ranges, build custom automations using simple if/then logic and monitor historical environmental trends.

That is a major upgrade over older-style controllers that only display readings on the wall and offer limited flexibility.

Smart Scene Automation Makes It Practical

One of the best parts of the system is the ability to create simple scene automation. For example, a grower can set: If CO2 drops below 900 ppm, turn the regulator on. If CO2 rises above 1200 ppm, turn the regulator off.

That kind of logic allows the system to maintain a target CO2 band automatically. But the real benefit comes when growers start thinking bigger. Because the system is Sonoff-based, scenes can be used creatively across the room, linking CO2, temperature, humidity and switching into one practical automation flow.

Why the Price Is So Groundbreaking?

R3399 for a complete app-based CO2 monitoring and control kit is genuinely groundbreaking. For years, growers have paid a premium for CO2 control because there were so few practical options in the market. Dedicated horticultural controllers have held their pricing because growers had little alternative.

This kit changes that by using a smart, connected automation ecosystem in a serious grow-room application. The result is a solution that is more affordable, more flexible, easier to expand, easier to monitor and easier to integrate into a full room-automation strategy.

The Bottom Line

This product is about more than just saving money on one controller. It is about giving growers access to a smarter, more connected way of running a grow room. With Sonoff at the core, CO2 automation becomes part of a complete control platform — one that can grow with the room, integrate with other devices and make advanced environmental control far more accessible than it has ever been before.

For growers who have been waiting for an affordable way to automate CO2 without sacrificing smart functionality, this kit is a genuine step forward.
