On test, the 93db siren built into the hub went off without a delay when anything triggered the window, door or motion sensors – as alerts are beamed to your smartphone. Like most of the kits on our list, installation is easy and mostly wireless, although the hub pairs via the ethernet port on your home wifi router to enable a secure connection. The latter are pricier when you buy for the first time, but you won't have to factor in the expense of replacement battery costs. A smart alarm is a wireless system that uses your home’s wifi network to connect the different components, which is why they are affordable and you may be able to install one yourself.

You will often receive more notifications with a motion sensor than you would from a window sensor – and if you receive too many, it’s tempting to shut down the whole system, which rather misses the point.

Many Wi-Fi-enabled devices still require a control hub, which usually connects to your router using an Ethernet cable. If you’ve already connected a voice assistant, smart heating and other wired devices, and run out of ports, don’t panic. With an inexpensive network switch, sometimes sold as an “Ethernet hub”, you can add up to 48 additional ports, each of which will behave as though it was a native part of your router. Netgear produces a reliable and easy-to-use range of switches for both home and office use.
