Bought 5 thermostats last year @ Aldi. Bought another this year -type Thermy from same company - looks the same. Saw & ordered the USB Bluetooth dongle. But it is not compatible with last years model! How shortsighted can marketing be? I will return both and get my money back! Proves your better off with a Brand that does not try to fool you. Could also not find the 'connect' button in the app.
