Depending on the use case, the controls for the lights or doors can be switched on and off. For the individual lights and doors, the corresponding theme as well as the message can be set.

Verdict
The clearest difference is update cadence: CoreConnect IOT at every 2 days against MQTT's every 11 months. CoreConnect IOT also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
