Hi - I’m wanting to install a smart device to measure the power usage of my air conditioner. It uses 15A to cool but 20A to heat. Is there a Shelly device that would work for this device? Thanks

This is a great little relay. Replaced 8 Fibaro dimmers that were flashing with the Ausgrid Ripple control. Really easy to install. Nice little web interface for initial setup whilst installing. Will use more of these.
