• Multiple Stations Support: Configure as many stations and devices as you have access to
• Comprehensive Sensors:
  • PV Input Power
  • AC Output Power
  • Battery Discharge/Charge Current
  • Battery Voltage & State of Charge
  • Grid Feed-in Power
  • Grid Import Power
  • Load Power
  • Monthly Statistics (PV generation, consumption, etc.)
• Control Entities:
  • Battery Charge/Discharge Limits (0-100%)
  • Grid Charge Power Limit (0-5000W)
  • Operating Mode Selection (Self-Use, Time-of-Use, Backup, etc.)
  • Battery Priority Mode (Solar First, Battery First, Grid First)
  • Grid Charging Enable/Disable
  • Grid Feed-In Enable/Disable
  • Backup Mode Enable/Disable
• Auto-calculated Metrics: Battery power, grid import, and solar coverage percentage
• Energy Dashboard Compatible: Sensors work with Home Assistant's Energy Dashboard

Installation

HACS (Recommended)

1. Open HACS in Home Assistant
2. Click on "Integrations"
3. Click the three dots in the top right corner
4. Select "Custom repositories"
5. Add this repository URL and select "Integration" as the category
6. Click "Install"
7. Restart Home Assistant

Manual Installation

1. Download the solar_of_things folder from this repository
2. Copy it to your Home Assistant's custom_components directory
3. Restart Home Assistant

Configuration

Finding Your Credentials

Before configuring the integration, you need to obtain your IOT Token, Station ID, and Device ID:

1. Log into https://solar.siseli.com
2. Open your browser's developer tools (press F12)
3. Go to the Network tab
4. Refresh the page
5. Look at the API requests (filter by "api" or "attribute")
6. Find and copy:
   • IOT-Token: Found in the request headers
   • deviceId: Found in request payloads (18-digit number)
   • stationId: Found in request payloads (18-digit number)

Adding the Integration

1. In Home Assistant, go to Settings → Devices & Services
2. Click + Add Integration
3. Search for "Solar of Things"
4. Enter your credentials:
   • IOT Token (required): Your authentication token
   • Station ID (required): Used to auto-discover all devices and enable monthly stats
   • Device ID (optional): If set, Home Assistant will only create entities for that one device

Multiple Stations / Multiple Accounts

To add multiple stations:

1. Add the integration once for each station/device combination
2. Use different Device IDs for each
3. Each integration instance will create a separate device in Home Assistant

Usage Examples

Energy Dashboard

Add the following sensors to your Energy Dashboard:

• Solar Production: sensor.solar_station_xxxxx_pv_input_power
• Grid Consumption: sensor.solar_station_xxxxx_grid_import_power
• Grid Return: sensor.solar_station_xxxxx_grid_feed_in_power
• Battery Charge: sensor.solar_station_xxxxx_battery_charging_current
• Battery Discharge: sensor.solar_station_xxxxx_battery_discharge_current

Automation Example

automation:
  - alias: "Notify when battery is low"
    trigger:
      - platform: numeric_state
        entity_id: sensor.solar_station_xxxxx_battery_state_of_charge
        below: 20
    action:
      - service: notify.mobile_app
        data:
          message: "Solar battery is low ({{ states('sensor.solar_station_xxxxx_battery_state_of_charge') }}%)"

Troubleshooting

"Cannot Connect" Error

• Verify your IOT Token is correct and hasn't expired
• Check that your Device ID and Station ID are correct (18-digit numbers)
• Ensure you have internet connectivity
• Token may expire - get a fresh one from the Siseli portal

No Data Showing

• Wait 5-10 minutes for the first data update
• Check the integration logs: Settings → System → Logs
• Verify your device is online and reporting data at solar.siseli.com

Sensors Unavailable

• Check if the specific sensor is supported by your inverter model
• Some sensors may only be available during certain conditions (e.g., battery sensors when battery is active)
