I chose to go with Delfin for my office. Being one of the premier automation companies in Chennai, they were referred to me by a friend. I was sceptical about hiring them for the entirety of it and initially planned with the automated lighting systems alone. Once the work was done, it mesmerised me and was convincing enough to get them to do the rest as well. With their safety and security systems installed, we are able to breathe easy. I would recommend them for home automation in Chennai as well. They maintain good work ethics and understand things easy.
