   A standard B2B KNX maintenance contract covers (1) an annual visit auditing PSUs, bus load (target below 30%), error counters and preventive replacement of critical components; (2) intervention SLAs typically 4 h business hours, 24 h business hours or 48 h depending on tier (tier 1 critical production, tier 3 comfort); (3) an automatic monthly backup of the .knxproj file to encrypted cloud storage; (4) catalogue and application-program updates; and (5) an annual review meeting with the client on observed usage and parameter adjustments. Pricing is usually 5-15% of the initial install cost per year. The recurring revenue is essential to integrator stability.
