Zigbee device needs to be added again after power cut

Hello there! I have several BTicino product connected to Home Assistant (shutter controls K4027C and light switches K4003C). They are recognized via ZigBee Coordinator deCONZ on a raspberry pi. The integration works OK, but it is not perfect. Indeed every time there is a power cut I have to repair most of them. Home assistant seems to find them immediately and remembers the names I have them (not the area though).

Is this a behavior to be expected? Is there a way to make these pairing (more) permanent?

Best
