Interface Creation & Startup Error Handling

+

Two new modules work together to centralize interface creation and provide startup visibility:

+ +

InterfaceFactory (src/interface_factory.py)

+

Factory pattern for centralized interface creation with integrated startup validation.

+

Responsibilities:

+ +

Usage in eos_connect.py:

+ 
from interface_factory import InterfaceFactory
+from startup_validator import StartupValidator
+
+# Initialize validator and factory at startup
+validator = StartupValidator()
+factory = InterfaceFactory(validator)
+
+# Create interfaces with error handling
+battery_interface = factory.create_battery_interface(
+    config=config['battery'],
+    time_zone=time_zone,
+    critical=True,  # Failure halts startup
+)
+
+load_interface = factory.create_load_interface(
+    config=config['load'],
+    time_frame_base=config['refresh_time'],
+    time_zone=time_zone,
+    critical=False,  # Failure doesn't halt, uses default
+)
+

Benefits:

+ + +

StartupValidator (src/startup_validator.py)

+

Lightweight facade for startup error registration to the logging system.

+

Responsibilities:

+ +

Method signature:

+ 
validator.add_error(
+    category="connectivity",        # initialization, configuration, connectivity
+    component="battery_interface",  # Component name for identification
+    severity="error",              # error or warning
+    title="Battery unavailable",   # User-friendly title
+    message="Connection timeout",  # Detailed message
+    action_required=True,          # Flag for startup panel badge
+    config_link="#battery",        # Link to config section
+)
+

Frontend Integration:

+

The web UI's startup panel fetches errors via:

+ 
GET /logs/alerts?startup_only=1&limit=20
+

Errors with metadata markers are parsed and rendered with:

+ + +

Startup Error Flow

+ 
Startup:
+  InterfaceFactory.create_*_interface()
+    │
+    ├─ Try to create interface
+    │   │
+    │   ├─ Success → return interface, user sees nothing
+    │   │
+    │   └─ Failure → catch exception
+    │       │
+    │       └─ validator.add_error(...)
+    │           │

+    │
+    └─ Frontend renderAlertSection()
+       ├─ Deduplicates errors by title
+       ├─ Sorts by severity (ACTION REQUIRED first)
+       ├─ Shows: timestamp, count, config link button
+       └─ User clicks → showConfigurationMenu(section)
+ +

Extending with New Interface Types

+

To add a new interface creation method to InterfaceFactory:

+
    +
  1. Add method to InterfaceFactory following the pattern of existing methods
    2. +
  2. Specify error category, component name, config link, and whether critical
    3. +
  3. Call from eos_connect.py during startup
    4. +
  4. If instantiation fails, StartupValidator.add_error() is called automatically
    5. +
  5. Errors appear in startup panel within 1-2 seconds
    6. +
+

Example:

Startup Error Metadata in Logs

+

Error messages can embed metadata for frontend parsing:

+ 
Log message format:
+"[component] Title: Message | Config: #section | ACTION REQUIRED"
+
+Examples:
+"[eos_backend] EOS Connection failed: Connection timeout | Config: #eos | ACTION REQUIRED"
+"[battery_interface] Battery SOC error: Authentication failed | Config: #battery | ACTION REQUIRED"
+"[load_interface] Load data unavailable: Request timeout | Config: #load"
+

Feed-In Pricing Calculation Details
+

The einspeiseverguetung_euro_pro_wh array is calculated from your feed-in price configuration and updated every 15 minutes:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
SourceFormulaUpdate FrequencyExample Calculation
Fixed(price_ct_kwh + static_adder_ct) × multiplier ÷ 100000 = €/WhManual(8 + 2) × 1.0 ÷ 100000 = 0.0001 €/Wh
Elpris DK(DKK/kWh × 100 ÷ 7.46 + static_adder_ct) × multiplier ÷ 100000 = €/WhDaily ~13:00 UTC(3.0 × 100 ÷ 7.46 + 2) × 0.95 ÷ 100000 = 0.000372 €/Wh
EPEX-Spot(api_price_ct + static_adder_ct) × multiplier ÷ 100000 = €/WhEvery 15 min(32.5 - 1.0) × 1.0 ÷ 100000 = 0.000315 €/Wh
+ +

Configuration Parameters:

+
    +
  • feed_in_source: Select pricing source (fixed, elpris_dk, epex_spot)
    • +
  • feed_in_price or API rate: Base feed-in price in ct/kWh
    • +
  • feed_in_static_adder (hot-reloadable): Additional fixed cost/benefit in ct/kWh (e.g., +2.5 for transport)
    • +
  • feed_in_multiplier (hot-reloadable): Percentage factor (0.5-1.5) for discount/premium strategy
    • +
  • feed_in_zone: Zone selection for Elpris DK (DK1/DK2)
    • +
+ +

Hot-Reload Note: Changes to feed_in_static_adder and feed_in_multiplier take effect immediately in the next optimization cycle without restarting EOS Connect.

+ +
Background Update Process
+

Feed-in pricing updates run continuously in the background:

+
    +
  • EPEX-Spot: Updated every 15 minutes, automatically aligned to market update times
    • +
  • Elpris DK: Updated once daily at 13:00 UTC (next day's prices)
    • +
  • Fixed: Manual - requires configuration change
    • +
  • Failure Handling: Up to 24 consecutive failures before falling back to last successful prices
    • +
  • Logging: Update status logged to file for troubleshooting
    • +
+

DescriptionHow to handle negative electricity market pricesHow to handle negative electricity market prices for grid purchases (not feed-in)
Valid Values - true - Limit feed-in price to €0 when market price is negative
- false - Always use the configured feed_in_price + true - Don't pay anything when market price goes negative (set buy price to €0)
+ false - Always use the configured market price (including negative values)
NotesUse true if your feed-in tariff pays €0 during negative market pricesThis setting only applies to grid purchase prices. Use true only with source: default (Akkudoktor) if you don't want to receive payments during negative price periods.

Price Modifiers

  • Fixed Adder: Add fixed costs (grid fees, taxes) in ct/kWh
  • Relative Multiplier: Apply percentage markup (e.g., 5%)
    • -
  • Feed-in Price: Set your solar export compensation rate
    • -
  • Negative Price Switch: Optional: don't pay when prices go negative
+

Dynamic Feed-In Pricing

+

New: Optimize battery discharge timing based on dynamic export prices, not just purchase prices:

+
    +
  • Fixed Feed-In: Configure a static export rate (simplest option)
    • +
  • Elpris DK: Real-time Danish spot prices for exports (DK1/DK2 zones)
    • +
  • EPEX-Spot: European spot market prices via Akkudoktor API (updated every 15 minutes)
    • +
  • Adjustments: Apply static adder (transport costs) and multiplier (discount/premium strategy)
    • +
+ +

Example: Instead of discharging to save €0.25/kWh purchase cost, EOS Connect now also considers you earn €0.40/kWh by exporting — leading to smarter discharge timing that increases your revenue.

+

    +

    If you see SSL certificate errors like:

    + + SSLError: Certificate verify failed
    + SSLError: [SSL: SELF_SIGNED_CERT_REJECT] self signed certificate +     +

    Step 1 (Recommended): Install a valid certificate using Let's Encrypt (free) via your reverse proxy or DNS.

    +

    Step 2: If Step 1 isn't feasible, enable this option in Settings → Data Source, then restart EOS Connect.

Solves the 2-day energy dispatch problem in-process via PuLP/CBC. Supports charging strategies: charge_before_export, maximize_self_consumption, attenuate_grid_peaks, discharge_before_import. Supports discharging strategies: discharge_before_import, emergency_reserve (end-of-horizon SOC floor). - `src/interfaces/optimization_backends/optimization_backend_local_evopt.py` Bridge between EOS request/response format and the MILP engine. Extends EVOptBackend for format transformation; runs the solver in-process.

    What is EOS Connect?

    Introduction

    -

    EOS Connect is an open-source integration and control platform for intelligent energy management. It acts as the orchestration layer between your energy system (solar panels, battery storage, inverters, EV chargers) and external optimization backends.

    EOS Connect is an open-source integration and control platform for intelligent energy management. It acts as the orchestration layer between your energy system (solar panels, battery storage, inverters, EV chargers) and optimization engines.

    - Important Understanding: EOS Connect does not perform optimization calculations itself. Instead, it: + Important Understanding: EOS Connect's primary role is integration and control. For optimization it can use either its built-in engine or an external server:
    • Collects data from your devices (battery SOC, PV production, load consumption)
    • Retrieves forecasts (PV generation, electricity prices, weather)
      • -
    • Sends all data to an external optimization engine (EOS or EVopt)
      • -
    • Receives optimization results back
      • -
    • Controls your devices based on those results (inverter, battery, EV charger)
      • +
    • Runs optimization (built-in, or sends data to an external engine)
      • +
    • Controls your devices based on the results (inverter, battery, EV charger)
    • Provides monitoring and manual control via web dashboard and APIs
    -

    The actual optimization calculations are performed by:

    Optimization backends available:

      -
    • Akkudoktor EOS (default) - Full-featured optimization engine - GitHub
      • -
    • EVopt - Lightweight, very fast alternative - GitHub
      • +
    • Local EVopt (default) — Built-in MILP optimizer, no external server needed. Based on the evcc-io/optimizer engine (MIT license). Supports configurable charging/discharging strategies and emergency battery reserve.
      • +
    • Akkudoktor EOS — Full-featured external optimization engine - GitHub
      • +
    • EVopt — Lightweight external alternative - GitHub
    - Think of it this way: EOS Connect is like a smart home hub that translates between your devices and a powerful optimization brain running separately. + Getting started: With the built-in local_evopt backend (default), you can start optimizing immediately — no external server to install or maintain.

This prevents expensive grid charging at end-of-horizon by teaching the optimizer: "After night comes day with PV". The extension activates when: - Forecast ends during nighttime (19:00-05:00) - Last 6 slots contain <100 Wh (confirming nighttime) - Adds 6 hours of conservative morning ramp [10-50%] at 06:00-12:00 PV capacity is extracted from the forecast data and used to scale the morning pattern generation, ensuring realistic expectations aligned with site history. Implemented methods: - _extend_forecast_with_morning_pv(): Detection & array extension logic - _generate_morning_pv_pattern(): Conservative morning ramp generation Test coverage: 4 new tests for extension logic, integration test with optimize() flow, 24 tests validate pattern generation and skip conditions. Also includes code quality improvements: attribute initialization, removed unused imports/parameters, added class docstrings. All 34 tests passing. --- .../optimization_backend_local_evopt.py | 184 ++++++++++++++++-- .../test_optimization_backend_evopt.py | 49 ++--- .../test_optimization_backend_local_evopt.py | 169 +++++++++++++--- 3 files changed, 327 insertions(+), 75 deletions(-) diff --git a/src/interfaces/optimization_backends/optimization_backend_local_evopt.py b/src/interfaces/optimization_backends/optimization_backend_local_evopt.py index 30cbb92f..ae782552 100644 --- a/src/interfaces/optimization_backends/optimization_backend_local_evopt.py +++ b/src/interfaces/optimization_backends/optimization_backend_local_evopt.py @@ -80,11 +80,20 @@ def __init__( ) self.num_threads = num_threads self.time_limit = time_limit - self.charging_strategy = charging_strategy if charging_strategy in CHARGING_STRATEGIES else "charge_before_export" - self.discharging_strategy = discharging_strategy if discharging_strategy in DISCHARGING_STRATEGIES else "discharge_before_import" + if charging_strategy in CHARGING_STRATEGIES: + self.charging_strategy = charging_strategy + else: + self.charging_strategy = "charge_before_export" + if discharging_strategy in DISCHARGING_STRATEGIES: + self.discharging_strategy = discharging_strategy + else: + self.discharging_strategy = "discharge_before_import" self.emergency_reserve_pct = max(0, min(80, int(emergency_reserve_pct or 0))) self.max_grid_import_w = max_grid_import_w self.max_grid_export_w = max_grid_export_w + # Initialize rolling average runtime tracking (5-element circular buffer) + self.last_optimization_runtimes = [0.0] * 5 + self.last_optimization_runtime_number = 0 def optimize(self, eos_request, timeout=180): """ @@ -118,13 +127,17 @@ def optimize(self, eos_request, timeout=180): if key in bat and isinstance(bat[key], list) and len(bat[key]) > n_valid: bat[key] = bat[key][:n_valid] + # Extend forecast with synthetic morning PV when forecast ends at night + # This teaches the optimizer that "after night comes day with PV" + evopt_request = self._extend_forecast_with_morning_pv(evopt_request) + # Optionally write debug file self._write_debug_file(evopt_request, "optimize_request_local_evopt.json") try: start_time = time.time() - optimizer = self._build_optimizer(evopt_request, eos_request, timeout) + optimizer = self._build_optimizer(evopt_request, timeout) evopt_response = optimizer.solve() elapsed = time.time() - start_time @@ -146,7 +159,8 @@ def optimize(self, eos_request, timeout=180): # Guard: handle infeasible / non-optimal result status = evopt_response.get("status", "") - if isinstance(status, str) and status.lower() in ("infeasible", "unbounded", "undefined", "not solved"): + status_lower = status.lower() if isinstance(status, str) else "" + if status_lower in ("infeasible", "unbounded", "undefined", "not solved"): logger.warning( "[OPT-LocalEVopt] Solver returned non-optimal status '%s';

    Unified Timeseries Data Source Guide

    +

    EOS Connect supports a flexible timeseries source for both electricity prices and PV forecasts. This unified approach allows you to fetch data from Home Assistant, custom HTTP APIs, or any endpoint that returns timeseries data in a standard format.

    + +

    Timeseries Data Format

    +

    The timeseries source expects JSON data in this standard format:

    +
    + 
    {
+  "data": [
+    {
+      "start": "2024-06-12T14:00:00Z",
+      "end": "2024-06-12T15:00:00Z",
+      "value": 0.25
+    },
+    {
+      "start": "2024-06-12T15:00:00Z",
+      "end": "2024-06-12T16:00:00Z",
+      "value": 0.28
+    }
+  ]
+}
    +
    + + + + + + + + + + + + + + + + + + + + + + +
    FieldDescriptionFormat
    startStart timestamp of the timeslotISO8601 (e.g., "2024-06-12T14:00:00Z" or Unix timestamp)
    endEnd timestamp of the timeslotISO8601 or Unix timestamp
    valueFor Prices: Price in EUR/Wh (e.g., 0.25 for 25 ct/kWh)
    + For PV: Generated power in Wh for the timeslot    		Number (float)
    + +
    + Time Resolution: EOS Connect auto-detects whether the timeseries is 15-minute (900s) or hourly (3600s) based on the timestamp differences. It automatically converts 15-minute data to hourly by averaging 4 consecutive values. +
    + +

    Home Assistant Integration

    +

    Home Assistant entity attributes can be accessed using the dot notation in data_path.

    + +

+  ]
+}
    +
    + +

    Testing Your Timeseries Configuration

    +

    Use the built-in connectivity test to validate your timeseries configuration before enabling it.

    + +

    HTTP Request:

    +
    + 
    POST /api/config/test-timeseries
+Content-Type: application/json
+
+{
+  "source": "price",
+  "data_url": "http://homeassistant.local:8123/api/states/sensor.grid_prices",
+  "data_path": "attributes.data",
+  "data_token": "eyJhbGciOiJIUzI1NiI..."
+}
    +
    + +

    Response (Success):

    +
    + 
    {
+  "success": true,
+  "message": "Successfully fetched 24 price values",
+  "sample_count": 24,
+  "first_entry": {
+    "start": "2024-06-12T14:00:00Z",
+    "end": "2024-06-12T15:00:00Z",
+    "value": 0.25
+  },
+  "last_entry": {
+    "start": "2024-06-13T14:00:00Z",
+    "end": "2024-06-13T15:00:00Z",
+    "value": 0.22
+  }
+}
    +
    + +

    Error Handling & Retries

    +

    EOS Connect automatically handles transient API failures:

    +
      +
    • Automatic Retries: Up to 3 attempts with exponential backoff (0.5s → 2s → 4s)
      • +
    • Cache Fallback: If API fails, uses the last successfully fetched data
      • +
    • Graceful Degradation: Continues running with cached data if available
      • +
    • Error Logging: Issues are logged with timestamps for troubleshooting
      • +
    + +

    Hot-Reload Support

    +

    All timeseries configuration fields support hot-reload — changes take effect immediately without restarting the application:

    +
      +
    • price.data_url, price.data_path, price.data_token
      • +
    • pv_forecast_source.data_url, pv_forecast_source.data_path, pv_forecast_source.data_token
      • +
    +

    Changes are applied within 1-2 seconds on the next update cycle.

    + +

Time Slot Configuration & Optimizer Constraints

+ +
+

EVCC as Price Source (price.source: evcc)

+

Use EVCC (Electric Vehicle Charging Controller) as your price source when you have an EVCC instance managing your electricity pricing or tariff data.

+ +

When to Use EVCC Price Source

+
    +
  • EVCC Integration: You already have EVCC configured with tariff/pricing data
    • +
  • Unified Control: Want to use the same EVCC instance for both EV charging and battery optimization
    • +
  • Automatic Tariff Sync: Tariff rates automatically synchronize between EVCC and EOS Connect
    • +
  • Multiple Tariffs: Need access to both grid consumption prices and feed-in tariffs from EVCC
    • +
+ +

Configuration Steps

+ +
+ Prerequisite: EVCC interface must be configured first (see EVCC Configuration). The price source will use the same evcc.url. +
+ +
    +
  1. Configure EVCC Interface: +
      +
    • Set evcc.enabled: true
      • +
    • Set evcc.url to your EVCC instance (e.g., http://evcc.local:7070)
      • +
    +
    2. +
  2. Enable EVCC Price Source: +
      +
    • Set price.source: evcc
      • +
    • price.token should remain empty (EVCC API doesn't require authentication)
      • +
    +
    3. +
  3. Optional - Add Feed-In Tariff (EVCC 0.132+): +
      +
    • If your EVCC instance publishes /api/tariff/feedin data, it will be used automatically for feed-in pricing
      • +
    • Set price.feed_in_source: evcc to use EVCC's published feed-in tariff
      • +
    +
    4. +
+ +

EVCC Price Data Format

+

EVCC provides electricity prices via the grid tariff API endpoint with 15-minute resolution:

+
+ 
GET http://evcc.local:7070/api/tariff/grid
+
+Response:
+{
+  "rates": [
+    {
+      "start": "2026-06-15T00:00:00+02:00",
+      "end": "2026-06-15T00:15:00+02:00",
+      "value": 0.3236
+    },
+    {
+      "start": "2026-06-15T00:15:00+02:00",
+      "end": "2026-06-15T00:30:00+02:00",
+      "value": 0.3113
+    }
+  ]
+}
+
+ +
Time Frame
+ + + + + + + + + + + + + + + + + + + + +
FieldDescriptionFormat
startStart timestamp of the price periodISO8601 with timezone (e.g., +02:00)
endEnd timestamp of the price periodISO8601 with timezone
valueElectricity price for that periodEUR/kWh (automatically converted to EUR/Wh internally)
+ +

Price Unit Conversion

+

Important: EVCC provides prices in EUR/kWh. EOS Connect automatically converts these to EUR/Wh for internal calculations:

+
    +
  • EVCC price: 0.120 EUR/kWh
    • +
  • Converted: 0.000120 EUR/Wh (÷ 1000)
    • +
  • Display: Always shown in EUR/kWh in the web UI
    • +
+ +

Automatic Updates

+

EVCC prices are fetched:

+
    +
  • On startup: Initial price load
    • +
  • Every refresh cycle: Default 10 minutes (configurable via refresh_time)
    • +
  • On configuration change: When price.source is changed to/from evcc, prices are fetched immediately (hot-reload)
    • +
  • On EVCC URL change: Automatic reconnection with new URL
    • +
+ +

Troubleshooting EVCC Price Source

+ + + + + + + + + + + + + + + + + + + + + +
IssueSolution
No prices showing +
    +
  • Verify evcc.enabled: true and evcc.url is correct
    • +
  • Check price.source: evcc
    • +
  • Verify EVCC is running and accessible at http://evcc.url:7070/api/tariff/grid
    • +
  • Check application logs for connection errors
    • +
+
EVCC connection timeout +
    +
  • Verify network connectivity to EVCC server
    • +
  • Check firewall rules allowing port 7070
    • +
  • Verify EVCC service is running: systemctl status evcc
    • +
+
Wrong prices after EVCC update +
    +
  • Trigger a manual config save to reload prices (hot-reload)
    • +
  • Check EVCC tariff configuration is correct
    • +
  • Verify price format matches expected EUR/kWh
    • +
+
Price source won't switch +
    +
  • Verify EVCC interface is not disabled or in error state
    • +
  • Check web UI Settings → Price Configuration for any errors
    • +
  • If using hot-reload, wait 5-10 seconds for connection to establish
    • +
+
+ +
