Energenie EG-PM2-LAN — Home Assistant Integration

Native Home Assistant integration for the Gembird / Energenie EG-PM2-LAN network-controlled power strip (4 switchable sockets).

Why this exists

The EG-PM2-LAN supports only one HTTP session at a time. If a second request arrives while a session is open, the device locks up and requires a power cycle. This integration solves that with an internal asyncio queue daemon that strictly serializes all device communication:

Every operation:  Login → [Switch command] → Read all 4 states → Logout

No concurrent sessions are ever possible, regardless of how many automations or UI interactions trigger switches simultaneously.

Features

• ✅ 4 switch entities (one per socket)
• ✅ All 4 socket states read in a single request
• ✅ Strict session serialization — device never locks up
• ✅ Immediate state update after switching (no waiting for next poll)
• ✅ Configurable poll interval (default 30 s)
• ✅ UI-based setup via Config Flow (no YAML needed)
• ✅ Works with both old and new device firmware
• ✅ German + English UI

Installation via HACS

1. In HACS → Integrations → ⋮ menu → Custom repositories
2. Add https://github.com/irstmon/egpm2lan-ha as type Integration
3. Install Energenie EG-PM2-LAN
4. Restart Home Assistant

Manual Installation

Copy the custom_components/egpm2lan/ folder into your <config>/custom_components/ directory and restart HA.

Configuration

1. Settings → Devices & Services → Add Integration
2. Search for Energenie EG-PM2-LAN
3. Enter IP address and password (if set on the device)
4. 4 switch entities are created automatically

Device Notes

• The device web interface must not be open in a browser during operation
• Default password is usually empty or 1234 depending on firmware version
• Tested with firmware that exposes sockstates JavaScript variable
• Legacy firmware using bare 0,1,0,1 HTML pattern is also supported

Migration from command_line switches

Remove your command_line entries from configuration.yaml and custom_command_line.yaml. After installing this integration, the old energenie_steckdose_1..4 entities will be replaced by switch.energenie_eg_pm2_lan_socket_1..4.

To keep your existing automations working, add these to your configuration.yaml:

homeassistant:
  customize:
    switch.energenie_eg_pm2_lan_socket_1:
      friendly_name: "Energenie Steckdose 1"
