Smart Building Software That Works With the Hardware You Already Own

Adam Hepworth

The short answer: you don't need to rip out working equipment to get a smart building. Smart building software designed as an operating layer connects the access control, smart locks, intercoms, thermostats, sensors and Wi-Fi you already own, ties them to your property management system (PMS), and runs the same workflows across buildings with different hardware brands. Equipment is replaced only where it genuinely can't be supported.

Why hardware flexibility matters

Most apartment portfolios are mixed. One property has one lock brand, another has a different access control system, a third was acquired with its own intercom. A platform that only runs its own devices forces a choice: replace working equipment, or run each building differently. Neither is good for the owner.

A hardware-flexible platform lets you standardize the operating layer, not necessarily every piece of hardware.

What can smart building software connect?

  • Property management systems: Yardi, Entrata, RealPage, AppFolio and ResMan.
  • Access control and intercoms: for example PDK, ICT, Mircom, LiftMaster myQ and ButterflyMX.
  • Smart locks: for example Salto, dormakaba, Yale, ASSA ABLOY and Kwikset.
  • Thermostats: for example Honeywell, Interel and UEI.
  • Leak detection and sensors: for example NEXT, frient and Ecolink.
  • Networks: for example RUCKUS, Cambium Networks and TP-Link.
  • Cameras, parcels, EV charging and payments.

The full list of systems that work with Della OS is on the integrations page.

How does it work across different vendors?

The platform normalizes each category. A "door" is a door whether it is opened by one lock brand or another, so a move-in workflow can say "give this resident their unit, the front entrance and the gym" without caring which hardware sits behind each door. That is what lets one operating standard run across a mixed portfolio.

What should you ask before you buy?

  • Which of our exact models are supported today, and which would need replacing, and why?
  • Can the same workflow run at a property with different hardware?
  • What happens when a network path fails? Do doors still work offline?
  • Who confirms compatibility before installation, and who supports it locally?
  • How much of the platform works with no new hardware at all?

Start with software, add devices over time

About 60% of what Della OS does needs no new hardware: PMS sync, the resident app, messaging, amenity booking, packages and maintenance. Smart locks, thermostats and sensors can be connected one building or one category at a time, and each joins the same standard.

Where Della OS fits

Della OS is a smart building and smart apartment platform built to sit above the hardware owners already have. A certified integration partner reviews each property's equipment before deployment and recommends replacement only where it can't be supported. Your PMS runs the business. Della runs the building.

Frequently asked questions

Is there smart building software that works with different hardware vendors?

Yes. Platforms designed as an operating layer, such as Della OS, connect supported systems from many vendors and run the same workflows across them.

Do I have to replace my smart locks to use a new platform?

Not necessarily. Compatibility is confirmed model by model, and locks are replaced only where they can't be supported.

Can one platform manage buildings with different access control systems?

Yes. The operating layer treats doors, credentials and permissions the same way regardless of the brand behind them.

How much works without new hardware?

With Della OS, about 60% of capabilities, including PMS sync, the resident app, messaging, amenities, packages and maintenance.
