Smart Switch with power meters

A Shelly A Smart Switch with a power meter (often labeled as “PM” in the Shelly lineup) is a smart relay that does two jobs at once: it acts as a remote-controlled switch and a digital energy monitor.

While a standard smart switch only turns power on or off, the version with a power meter includes internal sensors that measure the flow of electricity in real-time.

Note: Whilst the Shelly configuration is mostly DIY, any electrical work must be done by a registered electrical contractor and we recommend Straton Electrical.
