Spot prices, gas, weather and heat pump signal — straight into your building management system, PLC or Home Assistant. Eight countries, one connection, SSL/TLS or plaintext for local controllers.
All calculations (tax, VAT, all-in price) happen server-side using a single formula — you never have to reconstruct anything yourself.
NL, DE, BE (Fluvius/Ores/Sibelga separately), FR, ES, UK, IT (6 price zones) and PL — with local taxes and grid costs.
96 day-ahead prices a day since the European 15-minute switch (NL/DE/BE/FR/ES/IT/PL). The UK still runs on an hourly basis.
Not the cheapest hour, but the hour with the lowest effective cost (price ÷ COP) — the USP.
Port 8883 (SSL) for production and Python clients, port 1883 (plaintext) for PLCs and EasyIO controllers on your own network.
Current weather data and forecast per city, plus derived signals: heating/cooling degree days, frost and heatwave risk, comfort category.
All-in TTF gas price per supplier, and normalised GBP/PLN rates including the Ofgem cap.
Every value is also published individually, so you only subscribe to what you need. Retained messages — your client gets the latest value straight away on connect.
Drive heating, cooling or charge points off the current market price — without maintaining your own price feed.
Ready-made JSON topics on a local, unencrypted port — exactly what a controller needs.
Individual topics per value make automations simple: no API parsing, just subscribe.
Dymergy delivers standard MQTT + JSON — no proprietary protocol. Connect it to any building management system that supports MQTT to control on energy price, including:
Prices exclude VAT. Every plan starts with a free, no-obligation first week (1 device) — after that you continue or cancel for free.
For one connection or a proof of concept.
For multiple sites or test environments.
For integrators with multiple client projects.
Yes. Every plan (Starter, Pro, Business) starts with a free, no-obligation first week with 1 device. After that it automatically continues into the chosen plan — you can cancel for free at any time.
Netherlands, Germany, Belgium (Fluvius, Ores and Sibelga separately), France, Spain, United Kingdom, Italy (6 price zones) and Poland — eight countries on one connection.
Yes. Port 1883 (plaintext) is intended for PLCs and EasyIO controllers on a local network; port 8883 (SSL/TLS) is the production port for Python clients and tools such as MQTT Explorer.
Electricity prices are refreshed every 15 minutes, at quarter-hour resolution where the market supports it (NL, DE, BE, FR, ES, IT, PL); the UK runs on an hourly basis. Weather and analytics data follow the same rhythm.
Starter from €15/month (1 device), Pro €40/month (3 devices), Business €99/month (unlimited), or Custom on request. Billed in EUR; all prices exclude VAT.
