Detailed comparative analysis

1. Total cost of ownership (TCO)

Initial cost vs long-term cost

KNX

• Initial cost: €8,000 - €15,000 (150m² house)
• Maintenance: Low
• Evolution: Modular and economical
• Lifespan: 20+ years

Loxone

• Initial cost: €6,000 - €12,000 (150m² house)
• Maintenance: Medium
• Evolution: Limited to Loxone products
• Lifespan: 10-15 years

2. Flexibility and scalability

In terms of flexibility, KNX takes a significant lead. Thanks to its open standard, you can integrate products from different manufacturers and evolve your installation according to your changing needs. Loxone, while offering a complete range, limits you to the brand's products only.

3. Ease of use

Loxone excels here with its modern and intuitive user interface. The mobile app is particularly successful and offers a consistent user experience. KNX, depending on the integrator, can offer variable but often less modern experience.

4. Support and maintenance

KNX benefits from a global network of certified integrators, guaranteeing local support availability. Loxone centralises its support, which can be an advantage for consistency but a drawback for local availability.
