Thanks! I was shocked by how easy it was to get up and running so massive props to the Nabu Casa team that created the ESPHome framework (and Home Assistant!). Once I get this cleaned up a bit and successfully 3D print the case, I'll throw all of this on Gitlab so others can make their own smart e-nail.
I'm hoping to also design a PCB so that all these components can just be dropped into place with minimal soldering required and I want to move to a bigger screen / touchscreen
Any z-wave or ZigBee lock like those from Schlage are great. You can then integrate it into Home Assistant where there are great integrations like keymaster that make it super simple to do management like what you've mentioned
