Devices with both heating.burners and heating.compressors features (e.g. Vitocaldens 222-F with CU401B_S controller) are now detected as Hybrid instead of HeatPump or GazBoiler. Previously, Hybrid was only reachable via the manual heating_type config option in HA, which was removed in home-assistant/core#165649. The regex-based auto-detect matched CU401B as HeatPump, losing all burner entities. This adds a feature-based fallback: after regex/role matching picks GazBoiler or HeatPump, the API features are checked. If both burners and compressors exist, the device is upgraded to Hybrid. If the API call fails, the original detection is kept. Fixes home-assistant/core#168288

Problem
Hybrid devices like the Vitocaldens 222-F (controller
CU401B_S) are detected asHeatPumpbecauseCU401Bmatches the heat pump regex pattern. TheHybridclass was never in the auto-detect list — it was only reachable via the manualheating_type: hybridconfig option in Home Assistant, which was removed in home-assistant/core#165649.This causes all burner entities to disappear, since
HeatPumpdoesn't exposeheating.burners.*features — onlyHybrid(which inherits from bothGazBoilerandHeatPump) does.Solution
After regex/role matching picks
GazBoilerorHeatPump, the device's API features are fetched and checked. If bothheating.burnersandheating.compressorsfeatures exist, the device is upgraded toHybrid.This is a fallback — the existing regex matching is unchanged. If the feature fetch fails, the original detection is silently kept.
Why not full feature-based detection?
Non-heating device types (ventilation, radiator actuators, room sensors, gateways) don't have obvious feature-prefix signatures, so they still need regex/role matching. This approach is the smallest change that catches all hybrid devices — current and future — without maintaining a model name list.
