Plexlog Integration for Home Assistant

Custom Home Assistant integration for Plexlog PV monitoring systems.

Fetches all stats from your PV system via the Plexlog Portal API and makes them available as Home Assistant sensors.

Sensors

Real-time Power (W)

• Production Power — Current PV production
• Consumption Power — Current total consumption
• Grid Feed-in Power — Current power exported to the grid
• Grid Consumption Power — Current power drawn from the grid
• Self-Consumption Power — Current self-consumed power
• Battery Charging Power — Current battery charge rate
• Battery Discharging Power — Current battery discharge rate

Daily Energy (kWh)

• Production Today — Total energy produced today
• Consumption Today — Total energy consumed today
• Grid Feed-in Today — Total energy exported to grid today
• Grid Consumption Today — Total energy drawn from grid today
• Self-Consumption Today — Total self-consumed energy today
• Battery Charged Today — Total energy charged into battery today
• Battery Discharged Today — Total energy discharged from battery today

Period Energy (kWh)

• Production This Month — Total energy produced this month
• Production This Year — Total energy produced this year
• Production Total — Total energy produced (all time)

Plant Info

• Plant Name — Name of the PV installation
• Plant Capacity — Rated capacity (W)
• Annual Target — Annual production target (kWh)

Device Sensors

Automatically creates sensors for each inverter, meter, battery, and wallbox connected to your system.

Installation

HACS (recommended)

1. Open HACS in Home Assistant
2. Click the three dots in the top right corner → Custom repositories
3. Add https://github.com/Solar-TechNick/Ha-Plexlog as Integration
4. Search for "Plexlog" and install
5. Restart Home Assistant

Manual

1. Copy the custom_components/plexlog/ folder into your Home Assistant config/custom_components/ directory
2. Restart Home Assistant

Configuration

1. Go to Settings → Devices & Services → Add Integration
2. Search for Plexlog
3. Enter:
   • Portal URL — Your Plexlog portal URL (e.g. https://yourreseller.data4.plexlog.de)
   • API Key — Created in the portal under Anlageneinstellungen
   • Plant ID — Numeric ID visible in the dashboard URL
4. The integration will verify the connection and create all sensors

Dashboard

A ready-to-use Lovelace dashboard is included in dashboard/plexlog_dashboard.yaml that replicates the Plexlog web portal layout with an overview card and 4 chart views (day, month, year, total).

Setup

1. Open dashboard/plexlog_dashboard.yaml
2. Replace all instances of PLANT_NAME with your device name slug (find it in Settings > Devices & Services > Plexlog > click your device > look at any entity ID)
3. In HA, go to Settings > Dashboards > Add Dashboard
4. Switch to YAML mode (three dots > Raw configuration editor) and paste the content

Note on Charts

Charts use HA's built-in long-term statistics and will populate over time from when the integration was installed. For the Total View with true yearly bars, consider installing apexcharts-card via HACS (see commented alternative in the YAML).
