Can be linked to Homey and Apple Home

I was looking for a reliable and smart lock. After extensive research, I ultimately chose the Bold Elite. It's easy to install and integrate into my smart home (matter). It works with Apple Home and Homey, allowing me to trigger all sorts of smart actions when the door opens or closes.
