Automate my 4-plex: Poke holes in my plan? Other suggestions?

[Richard S.]

I own and self-manage a 4-plex in a neighborhood about 30 minutes from my house, 5 minutes from my place of employment. I plan to purchase an internet plan for the site and install a mesh wireless router system to boost the signal to all 4 tenants. Here is why I want to do this:

1. Use this as an optional revenue stream in providing WIFI to the tenants at a low cost.

2. Run security cameras in the laundry room (had a few issues with theft), boiler room, and the outside of the building for tenant security/general monitoring. Also can use to watch irrigation system and ensure it is running on time.

3. Install water sensors in all leak prone areas of the apartment and set up the automated alert system.

4. Use leak sensors (Yolink WIFI water sensors)  to close a mainline water shutoff valve, either automatically or from the app upon notification.

5. Control and monitor the irrigation system over WIFI with an Orbit Bhyve controller (ROI: can rain delay to save water automatically).

6. Use WIFI controlled door locks on front hallway and boiler room to allow access to contractors when I am unable to be there (not access to resident units - I will always be there when contractors are there).

Much of this likely seems like overkill, but my experience has been that installing these systems provides significant peace of mind and allows for further automation (Example: water leak: Open maintenance ticket and dispatch automatically). Any changes you would make here? Equipment suggestions? Automation hacks or podcasts/blogs I should read about this? 

Thanks for your input and time!
