The idea was that you'd have a fancy app that would let you "register" guests and the doormen would receive notifications about this with information about the guests (privacy concerns anyone?!).
In practice all of the following happened:
- Nobody used the app. I believe that nobody in that building even knows _how_ to use the app, including staff. My landlord had no idea, the doormen had no idea, etc. What ended up happening is that the concierge desk got a "blessed" landline phone and anyone who knew that phone number was implicitly "authorised" to allow them to let anyone in. Some doormen didn't even bother and just let anyone in who looked like they wanted to enter.
- Unannounced visitors had absolutely no way to make themselves known to you if they didn't have another way to contact you (e.g. technicians showing up). This actually happened to me once with a delivery driver who somehow didn't get my phone number, and got stuck in "doorman limbo" until I realised that something was off and went downstairs to ask the doorman if he'd seen anyone, and found the poor guy hanging out in the lobby.
- On the off chance that somebody would have figured out how to use the app, it's likely it wouldn't have worked because I don't think any of the workflows of anyone there involved looking at whatever/wherever the app was supposed to do its thing.
This is just the most recent example of this kind of crap for me. Sometime earlier I had an experience with a similar building in Oslo, where I ended up being the only person who could get into the building during a power outage because I absolutely insisted on having a physical key for the front door.
Internet connected "things" just suck.
