Multi-device bundle builder, starter kit with progressive discount

The bundle builder is the single biggest AOV lever for multi-category smart-home retailers. The pattern:

• Step 1: pick a hub, SmartThings, Aqara M2, Lutron Caséta, or "I have one already." Default to a SmartThings or Matter-over-Wi-Fi controller bundled in.
• Step 2: pick 1-3 cameras, with Ring Protect / Nest Aware / Wyze Cam Plus optional add-on.
• Step 3: pick a smart lock, with pro-install service offered.
• Step 4: pick a doorbell.
• Step 5: pick a thermostat, with HVAC pro-install if Nest / ecobee / Honeywell.

Magento mechanics: bundle products + Sales Rules driving progressive discount tiers. 5% off at 3 devices, 10% at 5, 15% at 7. Hub-required logic auto-injects the hub when any Z-Wave or Zigbee device is added, no more support tickets from customers who bought a Z-Wave lock without the hub. Hyvä + Alpine.js for the configurator state so the price recalc stays under 80ms INP even on a 12-device configuration.

AOV lift vs single-SKU smart-home carts: 2.3-3.1x in my client data. Critical: anchor the discount visibly at each step ("Add a thermostat: save 10%") so shoppers see the progressive-discount gradient pull them forward.
