Add-on from my repository (GitHub - fuatakgun/eufy_security_addon) is archived and not updated anymore. As called out in README file on integration, you need to use this repository (GitHub - bropat/hassio-eufy-security-ws: Official eufy-security-ws Home Assistant add-on repository)
Not sure if smart safes are supposed to be unlock remotely. I would create an issue to bropat’s repository, share the device and get support. If any new service is needed on home assistant end, I can help.
