For B&Bs and guest houses that want to avoid lights left on in empty rooms. The Aqara FP1E presence sensor detects whether anyone is in the room, even sitting still, and the T1 relay module switches the light off when the guest leaves. A sensor measures temperature and humidity. Everything goes through the M100 hub and is managed in the Aqara Home app.
What it does
- The FP1E sensor detects presence by radar, including someone sitting or lying down, not just movement.
- When the room stays empty for the time set, the T1 relay module switches the main light off.
- The switch in the room keeps working: the T1 module is wired behind the existing switch insert.
- The T1 temperature and humidity sensor reports in the app whether the room is too hot, too cold or too damp, between one guest and the next as well.
- In the app you see which rooms are occupied and which lights are on, useful for turnarounds and the evening check.

Before you order
Do you need a hub?
Yes, and it is included: the Aqara M100 hub brings the presence sensor, the relay module and the climate sensor into the app and runs the automations. One hub covers the whole place as long as the rooms are within its range; for larger buildings get in touch through the contact page.
How does it differ from an ordinary motion sensor?
A motion sensor switches the light off if the guest sits still reading or falls asleep. The FP1E sensor uses radar that picks up even small movements such as breathing, so it knows someone is there even when they are still and only switches off when the room really is empty.
Do you need an electrician?
Yes, for the relay module: it wires into 230V behind the switch, with live and neutral. The connections must be made by qualified personnel, with the installation isolated. The hub, the presence sensor and the climate sensor, on the other hand, you can fit yourself, on a USB supply or batteries.
What if there is no neutral in the box?
The T1 module in this kit needs a neutral. If only line and lamp return reach the back of the switch, you need a no-neutral module or a neutral pulled into the box: get in touch through the contact page and we will tell you which version fits.
Does it work with Alexa, Google Home or Apple Home?
Everything is managed in the Aqara Home app. The M100 hub supports Matter, so the devices connected to it can also appear in Apple Home, Alexa or Google Home where the manufacturer supports it. The light can always be controlled from the wall switch as well.
What happens if there is no internet?
The switch in the room always switches the light on and off. Automations between Aqara devices paired with the same hub can run locally, so switch-off on absence keeps working; you get no notifications and cannot see the status remotely until the line is back.
Can I extend the kit to other rooms?
Yes: each extra room needs a presence sensor, a relay module and, if you want one, a climate sensor, all paired to the same hub. Get in touch through the contact page with the number of rooms and we will put the configuration together.
What if a product is out of stock on Amazon?
An item can sell out or change version. Get in touch through the contact page quoting the kit code: we will point you to an alternative that works with the other devices and with the same app, so you keep a combination we have checked and you do not have to go back over anything yourself.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon, as with any other order: 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 needed to fit them.
