No, don’t worry: it’s not another terrible mouse design from Apple. This is the Tempo from UK-based Blue Maestro, and it’s a smart Bluetooth thermometer disguised as a pebble.
It’s actually a pretty cool-sounding device. It is weatherproof and durable (even the screws for the battery cover – 2xAA – are made from brass), and disguised so that you can leave it outside without tempting some drunken teenagers to steal it from your garden. It uses low-power Bluetooth to communicate with the free Tempo app, so you can just leave it outside until you need to check the temperature.
Right now I achieve the same thing by opening up my bedroom door and stepping out onto the balcony, checking to see whether I’ll need three wooly layers or four before venturing out into the East German winter. With Tempo I could do the same thing form bed.
The pebble will also keep a record of the temperature for the past 24 hours, so you can pick up the history whenever you check in. And of course you can also use it indoors, or use a clutch of the things to monitor different spaces.
The cost is just £29, or $48, and it comes in a range of natural colors.
