I don't think it's a member only deal, either. This set is wireless and has the ability to check temperature in your house and using the outdoor probe, any outdoor temperature, from anywhere in the world through the app.
You can also set up temperature alerts (both indoor and outdoor temp) through the app.
You also get free NWS forecasts straight to the station, maybe this matters to you.
This is a great set that retails for $42 on Amazon and more expensive elsewhere:
