Control4 vs Savant vs Crestron vs Home Assistant
Four approaches to home automation, with different ownership and support requirements. Compare the configured system, the features you need, and who will maintain it before choosing a platform.
Plan for Ownership and Support
Before choosing an integrated system, establish what you can change yourself, what requires a specialist, and how support transfers if your provider changes. Owner controls and programming access differ by platform, version, and configuration.
Dealer-Dependent Systems
- Confirm which changes the owner can make and which require a specialist
- Request current licence, remote-service, and maintenance terms
- Proprietary hardware with limited device compatibility
- Ask how another qualified provider can take over support
Open Platform (Home Assistant)
- Full control to modify your system at any time
- Budget for hardware upkeep and any connected services
- Check exact device integrations and supported features
- Choose self-management or a qualified support provider
Key takeaway: Ask for the full ownership picture before you sign: installation, licences, remote access, programming changes, support, and hardware replacement. An open platform changes how support is arranged; it does not make maintenance disappear.
The Contenders
Four smart home platforms, from open-source to ultra-luxury. Each one handles automation, pricing, and ownership differently.
Control4 (Snap One)
Professionally integrated controls. Confirm the exact devices, owner tools, and support arrangement in a current proposal.
Savant
Integrated home controls and interfaces. Evaluate supported equipment and ongoing ownership with the proposed installer.
Crestron
Control and AV systems with requirements that vary by platform and project. Scope the necessary specialist work before comparing prices.
Home Assistant
Open-source automation with a broad integration ecosystem. Hardware, supported features, and local versus cloud behaviour need to be checked for the exact devices in your home.
Head-to-Head Comparison
Use this checklist when comparing current proposals. Platform features and licences change; ask the provider to confirm the exact hardware, software, services, and access included in your system.

Prices are approximate for professionally installed systems as of February 2026. Costs vary significantly by home size, device count, and dealer region.
Control4
Mid-Market, Dealer-Installed
Control4 is a professionally integrated automation platform. Evaluate the proposed equipment, owner controls, supported integrations, and service arrangement. A demonstration of your required functions is more useful than a broad brand ranking.
Professionally integrated controls. Confirm the exact devices, owner tools, and support arrangement in a current proposal.
Ask which routine changes the homeowner can make and which require a dealer or specialist tools. Verify current connected-service terms, access to documentation, and the process for changing support providers.
Best For
Consider this approach if the demonstrated controls, equipment compatibility, and available professional support fit your requirements. Compare like-for-like proposals rather than assuming a platform always costs more or less.
Savant
Luxury-Tier, Design-Forward
Savant offers an integrated approach to home control. If the physical remotes and interfaces matter to you, try them with the required functions and ask what is supported in the proposed configuration.
A Savant proposal should identify equipment, supported integrations, programming, licences, and any ongoing services. Review both the initial scope and the terms for future changes instead of relying on a broad installed-price range.
Discuss long-term support with the proposed installer. Ask who holds the system documentation, how another qualified provider takes over, and what happens if a controller or connected service becomes unavailable.
Best For
Consider this approach when a demonstrated interface and integrated experience fit the household. Assess the proposal against required functions, usability, maintenance, and budget.
Crestron
Commercial-Grade, Ultra-Luxury
Crestron offers control and AV products for residential and commercial applications. For a home, distinguish the specific platform and equipment proposed, because configuration, programming, and support requirements vary.
For a Crestron project, define the required audio and video routing, control interfaces, lighting, and other functions. Obtain a scope from the appropriate specialist that identifies the platform, equipment, programming work, and handoff.
Ask how future changes are priced, what project files or backups can be provided, and which services require ongoing payment. Compare a dedicated AV design with a general-purpose automation design only when both meet the same requirements.
Best For
Consider a specialist AV approach when the routing, synchronisation, interfaces, or support requirements call for it. Simple household routines may need a different scope from a dedicated cinema or multi-room distribution system.
Home Assistant
Open-Source, No Dealer Required
Home Assistant is an open-source automation platform that runs on hardware you manage. Supported local integrations can operate without the internet; cloud-connected devices and services retain their external dependencies. Review the exact integrations and test the required functions.
Home Assistant can be installed on dedicated local hardware and connected to supported devices. Total cost depends on what you retain, what needs replacing, and how much integration and testing is required. The software does not require a dealer, but ongoing maintenance and connected services still need to be budgeted.
Home Assistant requires a deliberate interface and maintenance plan. Check the supported features for each device and voice service, keep physical controls usable, and test backups and recovery. A professional setup should include clear documentation and ownership.
Best For
Consider Home Assistant when ownership and flexibility fit your needs and you can support the maintenance involved. Test your required device functions and recovery process. Our smart home guide covers planning and handoff.
Key takeaway: Choose by required functions, usability, and ownership. Home Assistant offers flexibility; specialist platforms may suit different control or AV requirements. Compare complete proposals and demonstrate the everyday experience before deciding.
Winner by Use Case
There is no single "best" platform. The right choice depends on what you prioritize most.
Best for Budget
Winner: Home Assistant
Compare an open-platform proposal with the alternatives using the same scope. Include hardware, configuration, licences, remote access, maintenance, and future changes. A lower initial price does not settle the total ownership cost.
Best for True Luxury Feel
Winner: Savant
The best-looking hardware and user interface of any smart home platform. Savant's touchscreens and Pro Remote are genuinely beautiful objects. If budget is not a concern and the physical design of your control interfaces matters as much as the automation itself, Savant offers an experience no other platform matches.
Best for Commercial AV
Winner: Crestron
Nothing else comes close in conference rooms, dedicated home theaters, and complex multi-zone AV distribution. Crestron's 50+ years of commercial AV engineering means they own this category. If your home has a real commercial-grade theater or you need boardroom-level AV control, Crestron is the right tool.
Best for Long-Term Value
Winner: Home Assistant
An open platform gives you more choice over how you maintain and extend a system. Check each device integration, keep recoverable backups, and document access so another qualified person can support it. Changes and updates still require time and testing.
Frequently Asked Questions
Common questions about choosing between dealer-installed and open-source smart home platforms.
Which luxury smart home system is the cheapest?
There is no useful universal price for a full-home system. Compare proposals with the same rooms, equipment, controls, installation, programming, and support. Include licences, optional remote services, future changes, and replacement parts. Home Assistant can offer flexibility, but hardware, setup, and maintenance still have a cost.
Can I switch from Control4 or Savant to Home Assistant?
Sometimes, but compatibility must be checked model by model. Standard wiring or network equipment may be reusable, while controllers, remotes, touchscreens, drivers, and device-specific features can require replacement. Inventory the current system and test representative devices before committing to a migration.
Do I need a dealer to maintain a Home Assistant system?
Home Assistant does not require a platform-appointed dealer. You can maintain it yourself or arrange professional help. Connected products may have their own licences or cloud services, and updates, backups, troubleshooting, and hardware replacement still need an owner. Leios can scope ongoing support separately.
Is Home Assistant reliable enough for a luxury home?
Reliability depends on the complete design: supported devices, network quality, power, backups, updates, and tested manual controls. Home Assistant can run local automations, while cloud-connected integrations still depend on their external services. Verify the required functions during an internet outage as part of acceptance testing.
What about commercial AV features like Crestron offers?
For demanding audio and video systems, start with the actual routing, synchronisation, control, and support requirements. Check the exact equipment and available integrations with the relevant specialist. A general-purpose automation platform is not automatically a substitute for a dedicated AV system.
