Iskra
The Iskra
Supported devices
This integration supports Iskra’s devices, which should not be confused with Iskraemeco, another manufacturer of energy meters commonly used by electrical distributors for billing purposes.
Energy meters
Most Iskra’s DIN rail mountable energy meters support Modbus RTU over RS485 and IR. To integrate them, you will need a Modbus TCP gateway or Iskra’s Smart Gateway:
- Impact series (IE38XX / IE14XX
) - WM series (WM3XX / WM1XX
)
Power quality analyzers
These devices typically support Ethernet connections and use Modbus TCP for data polling:
- iMT/MT series (MTXXX / iMTXXX
) - iMC/MC series (MCXXX / iMCXXX
)
Configuration options
There are two ways to configure your devices with Home Assistant:
Smart Gateway with REST API
If your device supports Modbus RTU over RS485/IR, you can use Iskra’s Smart Gateway to connect them via the REST API:
- Smart Gateway: Connect your devices to the Smart Gateway and add your devices to the Smart Gateway’s configuration. It’s also recommended to set a static IP on your smart gateway.
- Home Assistant: Add the Iskra integration, enter the Smart Gateway’s IP address, and select RestAPI as the connection type within the Home Assistant integration. If authentication is required, Home Assistant will prompt you to enter the Smart Gateway’s credentials. All devices configured on the Smart Gateway will be automatically added to your Home Assistant.
Modbus TCP connection
If your device supports a direct internet connection, such as PQ meters (iMC/MC series/ iMT/MT series usually), you can use Modbus TCP:
-
Device: Find your device using the MiQen
software and configure it to use a static IP. - Home Assistant: Add the Iskra integration, enter the device’s IP address, and select Modbus TCP as the connection type within the Home Assistant integration. Home Assistant will prompt you to enter the Modbus TCP port and Modbus address of your device.
Configuration
