In the bedroom one Sonoff AirGuard monitor measures CO2, a second monitor measures PM2.5 and PM10 fine particulates, and a Sonoff Wi-Fi socket switches a purifier or a dehumidifier on when needed. The eWeLink app shows the night's air quality and lets you set automatic switching on the thresholds.
What it does
- The Sonoff AirGuard measures CO2 in the bedroom: at night, with the door and window shut, it shows when the air goes stale.
- The PM2.5/PM10 monitor measures fine particulates and tells you when it is worth switching the purifier on.
- The Sonoff S60TPF socket switches the purifier or the dehumidifier on when a threshold is passed and off when the readings are back to normal.
- The socket meters the consumption of whatever is plugged into it.
- The overnight history in the eWeLink app helps you work out when to open the window or adjust the ventilation.

Before you order
Do you need a hub?
No. The monitor and the plug connect straight to the home Wi-Fi and are managed from the eWeLink app. All you need is a router with 2.4GHz Wi-Fi covering the bedroom.
Does it work with any air purifier or dehumidifier?
It works with appliances that switch themselves on as soon as they get power, for example those with a mechanical switch or last-state memory. If the appliance only has touch buttons and comes back off, the socket is not enough. Check the manual first.
Do you need an electrician?
No. The monitor sits on a cabinet and the plug goes into the wall socket. There is nothing to wire into the electrical installation: the wall socket simply has to suit the power of the appliance connected.
Does it work with Alexa and Google?
Yes, through the eWeLink integration: the socket shows up in the assistant and switches on by voice, and the readings may be visible depending on what the assistant supports. The automatic thresholds are set in the eWeLink app.
What happens if there is no internet?
The monitors keep measuring and the plug stays in its last state, or can be switched with its own button. Scenes between monitors and plug, and the notifications, depend on the connection and on the manufacturer's functions, and resume when the line is back.
Does the CO2 monitor tell me the temperature as well?
The kit is built for CO2 and particulates. Whether the monitor also shows other readings depends on the model, as stated by the manufacturer. For accurate temperature and humidity control in the room, get in touch through the contact page and we will tell you which Sonoff sensor to add.
Can I add devices?
Yes: more Sonoff sockets for a second appliance, more monitors for the other bedrooms, or Sonoff temperature and humidity sensors. They appear in the same app and work in the same scenes.
What if a product is out of stock on Amazon?
Get in touch through the contact page quoting the kit code: we will point you to an alternative that works with the rest of the set, so you do not have to hunt for an equivalent model yourself and risk buying a part that will not talk to the other devices in the kit.
Why buy on Amazon?
Purchase, delivery, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon when you buy. The kit is our own work: we picked parts that work together, plus the accessories you actually need to fit it.
