How does it work and when is it available?
3. Is it secure?
The system was introduced not too long before hundreds of thousands of spam emails were sent out by an internet-connected fridge, TVs and home entertainment centres, highlighting risks of the Internet of Things (IoT).
Roberta Bigliani, associate VP and head of IDC’s energy’s insights, told CBR: "We have recently seen cyber attacks via home-related devices. And we all know that consumers are not very good at setting things in an accurate way to prevent this.
"But this is nothing different to home banking, mobile phones etc, so it is an important issue which will not stop the roll-out in consumers’ world."
She added: "Major actions will need to be undertaken by companies. I mean they need to prevent hackers from penetrating their systems via consumer devices.
LG joins as the market for home automation with smart devices grows increasingly competitive. Smart home services sales are set to hit $71bn by 2018, up from $33bn in 2013, according to research from Juniper Research.
Samsung unveiled another smart home system at CES, which uses a single app that home owners can access to control Samsung-branded appliances using their smartphone, tablets and other devices.
Automation startup firm Revolv also launched an app at the end of last year that connects and consolidates home automation devices within your home, and Piper launched its own smart home and security device in January.
Bigliani said: "The connected home space is quite crowded with many tech providers positioning on it. I think one to look at is Google. And also utilities, for instance RWE in Germany, DT and Telco, are looking for their space."
5. What else should you know?
According to Jacob Kastrenakes from The Verge, HomeChat doesn’t understand typos or less-than-perfect wording.
"It also had some trouble connecting to appliances when we saw it at LG’s CES booth, but the service is still just a prototype and those kinks could be worked out," he wrote in January 2014.
Another issue facing the smart system is interoperability between brands, according to Bigliani.
She said: "I personally believe that the most important thing in the entire story is to have a standard platform for IoT connectivity (or few). This is the only condition to create mass market products."
