What wireless power monitoring device are you using for your electricity smart meter in Melbourne?

We have a smart meter with Powercor and are keen to start monitoring our power usage. I have seen several devices that connect to the meter wirelessly and have a device in the house with a screen. Doesn't need to be super complicated.

Couldn't see anywhere else appropriate to ask this question, but if this is not the place let me know. Otherwise, would appreciate feedback on the wireless device you have connected to your smart meter and the functionality it gives you.
