The 47th annual Consumer Electronics Show in Las Vegas hasnt even officially begun yet, but that hasnt stopped tech companies from unveiling their latest innovations to the audience of journalists, exhibitors and industry experts already assembled in the city.

Connectivity and the Internet of Things look to be the watchwords for this years show, with many devices boasting features that learn user patterns, or connect with other technology to provide analytics, feedback or simply extra utility.

Among the products on show at the CES Unveiled preview night on Sunday were Roost smart batteries, which use built-in wi-fi antennas to transform existing smoke detectors into smart devices, replacing the conventional 9-volt battery with an alternative that alerts your smartphone when it is running low on charge.

Parrot, largely known for drone and headphone technology, introduced two new devices, Pot and H2O, aimed at bringing the Internet of Things to green-fingered consumers. Pot, a smart planter for house plants and gardens, contains sensors that measure soil moisture, fertiliser, ambient temperature and light, notifying you via your smartphone on how best to care for your plant, while H20 is a smart spigot that can be placed into soil with a screw-top water bottle attached, watering your plants when they require it for up to three weeks on its own.

Even pets are now able to get in on the activity tracking trend, with the Tagg GPS Plus, a wearable tech device for dogs which features built-in GPS tracking for finding lost pets, activity monitoring capabilities to make sure your dog is getting enough exercise, and an ambient air temperature sensor which alerts owners when dogs are too hot or cold.

In addition to Internet of Things devices, CES is expected to provide consumers with a glimpse at the latest in drones, smartwatches, 3D printers and home robotics, as well as more traditional technology like televisions, stereos and cameras. Well continue to provide you with news from Las Vegas, which you can find under the CES 2015 tag.
