It has 439 installs sharing analytics, needs the vendor's cloud and was last updated October 26, 2026. Rynkowa Cena Energii (RCE) shows energy market prices published by PSE as sensors in Home Assistant. Prices come from PSE's cloud API with 15-minute resolution, and a second data source adds the Energy Compass report with PSE's recommendation for energy use in a given hour. It adds price sensors for the current, previous, next and tomorrow periods, daily statistics such as average, maximum, minimum and median, and a prosumer selling price sensor. Binary sensors report the lowest and highest price, threshold crossings, and cheap, expensive and second expensive time windows, each with its own search range and duration. Options cover the price unit, hourly average prices for net-billing, gross prices with VAT, and a Lite mode that publishes only the basic price and Energy Compass sensors. It is set up in the UI.

[Open it in the Marketplace](https://my.home-assistant.io/redirect/marketplace_repository/?owner=Lewa-Reka&repository=ha-rce-pse&category=integration) ## Supports - **Uses the vendor's cloud**: Needs an internet connection and an account with the vendor. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### RCE PSE Configuration - **Lite mode**: A simplified mode focused on ensuring PSE data is fetched and exposed in the attributes of the available sensors. It publishes the current price, tomorrow price and Energy Compass sensors. All analyses, statistics, windows, thresholds and automations can then be built by the user from that data. - **Price unit**: Unit for all price sensors - **Decimal places**: The recommended value is 2 for PLN/MWh and 5 for PLN/kWh. Default 2. - **Hourly average prices**: Useful in net-billing settlements due to prosumer metering with hourly accuracy despite 15-minute prices. In this mode, the average price for a given hour is calculated from published quarter-hour prices. Settlement according to Art. 4b sec. 11 of the Ustawa o OZE - **Gross prices (with VAT)**: When enabled, all prices are converted to gross using VAT (currently 23%), so you do not need to apply VAT in automations - **Enable cheap window**: When disabled, the integration does not publish cheap-window sensors and does not calculate this window. - **Time window start**: Start of the search range. Same calendar day only. - **Time window end**: End of the search range. Use 00:00 here to mean end of that calendar day. - **Search window duration**: Length of the continuous window to find. Must fit inside the search range. - **Enable expensive window**: When disabled, the integration does not publish expensive-window sensors and does not calculate this window. - **Time window start**: Start of the search range. Same calendar day only. - **Time window end**: End of the search range. Value 00:00 means end of that calendar day. - **Search window duration**: Length of the continuous window to find. Must fit inside the search range. - **Enable second expensive window**: When disabled, the integration does not publish second-expensive-window sensors and does not calculate this window. - **Time window start**: Start of the search range. Same calendar day only. ### After setup - **Lite mode**: A simplified mode focused on ensuring PSE data is fetched and exposed in the attributes of the available sensors. It publishes the current price, tomorrow price and Energy Compass sensors. All analyses, statistics, windows, thresholds and automations can then be built by the user from that data. - **Price unit**: Unit for all price sensors. WARNING! After changing, statistics may mix old and new units. Update automations and the low and high price thresholds when switching between PLN/MWh and PLN/kWh - **Decimal places**: The recommended value is 2 for PLN/MWh and 5 for PLN/kWh. - **Hourly average prices**: Useful in net-billing settlements due to prosumer metering with hourly accuracy despite 15-minute prices. In this mode, the average price for a given hour is calculated from published quarter-hour prices.
