Z-Wave Light Switches

Evida/U-Fairy Z-Wave 3-gang light switch

One of the most common things you’ll want to or expect to do with a home automation system is to control your lights. While there are many types of light switches available, choosing the right one seems to be constrained by existing physical wiring, unless you don’t mind rewiring your home.

Shopping With Just My Phone

Android Pay on Nexus 6P

Since the launch of Android Pay in Singapore, I’ve been seizing every opportunity to pay with my smartphone. I know it’s still a long time before we can leave our physical wallets and purses at home, but I’m happy that we’re taking steps in that direction.
