Doorbell not auto reconnecting to wifi after power outage

Every time there's a power cut the doorbell is not reconnecting to the wifi. I have to press the orange button and redo the setup of connecting back the doorbell to the wifi and then it's working fine until the next power cut. Is this normal ? I think the doorbell should reconnect by itself to the wifi. If I'm loosing power at night the bell will ring once every couple of second until the orange button is pressed again. I like this doorbell but I will have to replace it by something else. Thank you for your answer.
