A major refinement release focused on Heat Pump & DHW intelligence, Battery Statistics, Smart Control, Command Center improvements and system reliability.
🌡️ Heat Pump & DHW
- Separate Space Heating consumption and thermal generation
- Separate DHW consumption and thermal generation
- New DHW · Heat Pump section in the Command Center
- Correct live Heat Pump thermal production
- Added Heating Circuit / Secondary Pump Speed mapping
- Improved Heat Pump mapping persistence and legacy migration handling
- Prevents circuit measurements from being double-counted in whole Heat Pump totals
- Improved Heat Pump circuit statistics and presentation
The new Heat Pump/DHW model has been validated on both Buderus and Viessmann Vitocal systems.
🔋 Battery Statistics
- New dedicated Battery Statistics page
- Live SOC and charge/discharge state
- Charging and discharging power
- Daily charged/discharged energy and throughput
- Battery history and contribution analytics
- Improved efficiency evidence semantics
- Learning-based battery intelligence
⚡ Smart Control & ELWA
- Improved Smart Control & Safety interface
- Cleaner ELWA configuration and control sections
- Fixed Smart Control bootstrap for newly registered Water Heater devices
- New installations can correctly move from Observe Only to Zeus permitted
- Existing safety, ownership and supervised-execution protections preserved
🖥️ Command Center
- Improved Heat Pump and DHW presentation
- Correct live thermal-production display
- Current-day DHW energy semantics
- Weather / Energy Prognose layout corrections
- Improved text and separator fit
- Existing kiosk geometry and energy-flow behavior preserved
🕒 Home Energy Timeline
- Improved registered-load activity detection
- Added hysteresis to prevent repeated false start/stop events
- Temporary unavailable/unknown measurements no longer create false transitions
🛡️ Reliability & Recorder
- Fixed oversized Daily Briefing attributes
- Fixed oversized Historical Chart Data attributes
- Prevents Home Assistant Recorder 16,384-byte attribute warnings
- Full live Zeus data remains available while unnecessary large payloads are excluded from Recorder
🔧 Device Manager
- Improved advanced Heat Pump mappings
- Improved optional-field save/clear behavior
- Cleaner legacy migration handling
- Improved Smart Control layout and readability
- Existing device configurations remain compatible
🧪 Real-world validation
v14.8.3 has been tested across real Home Assistant energy installations including:
- Fronius solar and hybrid systems
- Battery storage
- Buderus heat pumps
- Viessmann Vitocal heat pumps
- my-PV AC ELWA 2
- go-e EV charging
- Smart meters and registered household loads
Thank you to the community testers who provided real-world measurements, screenshots and feedback throughout development.
