Need Help Making My Armored Front Door Smart (Zigbee + Physical Key Backup)

Hello everyone, I want to make my front door smarter because it’s located at the bottom of a staircase. Currently, I have to walk downstairs every time I need to open it. I’d like to install a smart lock that integrates with Home Assistant (via phone/app control), but I have specific requirements: Physical key backup: Must support traditional key entry as a fail-safe (e.g., for dead batteries or system failures). Zigbee support: Needs to work with Zigbee—not Wi-Fi—to integrate into my existing smart home setup. (but I can live also with a Non-Zigbee device if it is difficult to find!) Compatibility with armored door: My door has 4 locking cylinders (see photos below). Photos of my door: https://preview.redd.it/moh7xn5ypp6f1.jpg?width=924&format=pjpg&auto=webp&s=9e4c3860ee8e492294439d07b12ddc886ab147ae https://preview.redd.it/5fey8zm0qp6f1.jpg?width=924&format=pjpg&auto=webp&s=3a227eef620e7d51e996b60104433ffb25e29e31 Questions: Which smart lock models would meet these requirements? Has anyone installed a smart lock on a similar armored door, can you give me some suggestions? Do I need special tools or modifications for installation? I’d appreciate advice from those with firsthand experience! Thanks in advance. submitted by /u/Caesar1989 [link] [comments]

Hello everyone,

I want to make my front door smarter because it’s located at the bottom of a staircase. Currently, I have to walk downstairs every time I need to open it. I’d like to install a smart lock that integrates with Home Assistant (via phone/app control), but I have specific requirements:

Physical key backup: Must support traditional key entry as a fail-safe (e.g., for dead batteries or system failures).
Zigbee support: Needs to work with Zigbee—not Wi-Fi—to integrate into my existing smart home setup. (but I can live also with a Non-Zigbee device if it is difficult to find!)
Compatibility with armored door: My door has 4 locking cylinders (see photos below).

Questions:

Which smart lock models would meet these requirements?
Has anyone installed a smart lock on a similar armored door, can you give me some suggestions?
Do I need special tools or modifications for installation?

I’d appreciate advice from those with firsthand experience!
Thanks in advance.
