2026-07-05 cluster-coverage audit findings for upcoming Matter 1.3/1.4 energy-management device types:

• Water Heater (0x050F; WaterHeaterManagement 0x0094 + WaterHeaterMode 0x009E): temperature will surface via the existing 0x0402 handler, management/mode clusters co-locate with it → hits the silent partial-coverage class (see companion issue) until a handler exists. EU-market 1.4 novelty.
• Device Energy Management (0x050D; DEM 0x0098 + DEM Mode 0x009F): typically co-located with the appliance it manages (heat pump, EVSE) → same class.
• Solar Power / Battery Storage / Heat Pump (1.4): no actuator cluster → resolve acceptably TODAY via the Energy measurement on a separate endpoint (IKEA GRILLPLATS): 0x90/0x91/0x9C → placeholder, no readings #79/PR Split-endpoint energy measurement attribution (IKEA GRILLPLATS) #80 matterEnergyMeter fallback (readings work; type-specific control missing).
• Thread Border Router mgmt (0x0452/0x0453): deliberate non-goal.

Revisit when a real device surfaces; the partial-coverage log (PR #80) will make these visible in user logs instead of silent.
