ecomain Integration With Home Assistant

Step 1: Connect ecoMain to Home Assistant

Sign in to your Home Assistant instance. Before connecting ecoMain, install the enecess integration. ecoMain supports multiple connection methods in Home Assistant. This guide demonstrates Automatic Discovery using local setup, which is the quickest way to prepare ecoMain for the Home Assistant Energy Dashboard.

For Manual Setup, Cloud Login, entity types, firmware requirements and troubleshooting, refer to the official enecess integration documentation.

Step 2: Add Grid Import and Export

Open the Energy dashboard from the left-hand sidebar, then select Edit. Under Grid connections, select Add grid connection.

For Energy imported from grid, search for all and select main_all_energy_fwd_total. For Energy exported to grid, select main_all_energy_rev_total. Leave Do not track costs selected for now.

Scroll to the Type of power measurement section. Select Standard, then choose main_all_power_rt. Select Save to complete the grid connection configuration.

Step 3: Add Solar PV Production

Under Solar panels, select Add solar production. In this example, solar production is connected to Channel 4. Search for ch4 and select main_ch4_energy_fwd_total. Set Solar production power to main_ch4_power_rt. Keep Don't forecast production selected, then select Save.

If your system includes a battery storage system, you can add it in the Home battery storage section by selecting the corresponding battery channel. This example system does not include battery storage, so this step is omitted.

Step 4: Add EV Charger, Heat Pump and Other Devices

Select Add device, then select the energy and power entities for the device you want to monitor.

For House Load, use main_ch5_energy_fwd_total and main_ch5_power_rt. Repeat the same process for additional devices. For example, Channel 6 is connected to an EV charger using main_ch6_energy_fwd_total and main_ch6_power_rt.

Step 5: Add Electricity Pricing with Nord Pool

After configuring the energy sources, you can enable electricity cost tracking using the Nord Pool integration. Return to Settings, Devices & Services, then select Add Integration. Search for Nord Pool and select the integration from the search results.

Choose the Nord Pool market area that matches your location or electricity market. Select the currency that corresponds to your electricity market, then submit.

Return to the Energy dashboard, select Edit, and open the existing grid connection. Select Use an entity with current price, then choose the current price entity provided by the Nord Pool integration.

Export compensation is optional. If your utility provider pays you for electricity exported to the grid, you can assign the appropriate pricing entity here. Otherwise, leave the default setting unchanged.

Step 6: Create Aggregated Entities for Multi-Phase Devices

Some devices, such as three-phase heat pumps, may use multiple ecoMain channels. You can combine several channels into one aggregated entity before adding the device to the Energy Dashboard.

In this example, Channels 1-3 are connected to heat pumps. To simplify the dashboard, these three channels are combined into one device so total heat pump consumption is displayed and tracked together.

Choose Power as the source type, keep Sum selected as the operation, and enter a descriptive name such as Heat Pump_power. A consistent naming convention makes entities easier to find later.

Repeat the process and choose Energy as the source type. Keep Sum selected, then enter a name such as Heat Pump_energy. Select the forward energy entities for the channels you want to combine.

Step 7: Verify Your Energy Dashboard

At this point, your Energy Dashboard should show the configured energy sources and devices. Immediately after setup, it is normal for some values to show 0 or for some charts to appear empty. Home Assistant needs time to collect and process energy data. It can take up to two hours before new data begins to appear.

After enough data has been collected, the dashboard will gradually populate with real-time power readings, energy usage, solar production and device statistics. Starting on the following day, the dashboard can display a complete day's worth of energy statistics.
