Hi all, I’ve been working on a Homey app called Eplucon Smart Control. The app started as a way to control and monitor an Eplucon / Ecoforest heat pump directly from Homey, but it is gradually becoming a more generic heat pump controller and optimizer as well. **Main features at the moment:** • Monitor heat pump temperatures, status and power • Control the living room temperature setpoint • Control the domestic hot water / boiler setpoint • Smart hot water planning based on electricity prices • Automatic Legionella cycle planning • Learning from previous hot water cycles to improve energy and runtime predictions • Dashboard widgets for home, hot water, heat pump and detailed home data • Optional energy split per operating mode: - Heating - Cooling - Hot water - Legionella - Standby • Support for dynamic electricity prices • Native Eplucon integration • Manual source mapping is being added so the app can also work with data from other Homey devices/integrations The goal is to keep the heat pump control, monitoring and energy optimization in one place inside Homey, without needing several separate apps or dashboards. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/2/92cf68de4788a27e33e84e08591de8bdfced2e59.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/5/15ae9e1898c04ea56f87e7570cf51a463806916a.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/e/be983e60de1af9717649ad57ed2bd3f48451bddb.jpeg) The app is currently under active development, so the Test version usually contains the newest features. **Test version:** > **[Heatpump Smart Control | Homey](https://homey.app/en-us/app/com.community.heatpumpoptimizer/test/)** > > Smart heat-pump comfort, clear energy insights and price-aware hot water. **Stable version:** [https://homey.app/a/com.community.heatpumpoptimizer/](https://homey.app/a/com.community.heatpumpoptimizer/) Feedback is very welcome, especially regarding: • Compatibility with other Eplucon / Ecoforest installations • Heat pump data and operating modes • Smart hot water planning • Dashboard widgets • Other heat pump integrations or data sources you would like to use If you test the app, please mention your heat pump type/model and how it is connected to Homey when reporting an issue. I’ll use this topic for updates, feedback and development discussion. ---

## Heatpump Smart Control for Homey Pro – Features (v1.5.3) Heatpump Smart Control is a Homey Pro app designed to monitor and optimize heat pump operation, with a particular focus on **smart domestic hot water heating, dynamic electricity prices and energy monitoring**. ### Main features - **Heat pump integration:** Connect directly to Eplucon/Ecoforest using your account credentials, including automatic module detection. Alternatively, connect compatible Homey devices and sensors manually. - **Smart hot water scheduling:** Automatically schedules water heating during the cheapest available electricity periods, based on current water temperature, expected energy consumption and heating duration. - **Self-learning predictions:** Uses historical heating cycles to improve predictions of energy consumption, heating time and boiler temperature loss. - **Dynamic electricity prices:** Supports Homey Energy, Tibber, ENTSO-E and external Homey price devices, including hourly and 15-minute electricity tariffs. - **Legionella protection:** Automatically schedules periodic high-temperature boost cycles, prioritizing cheaper electricity periods and verifying whether the heating cycle was successful. - **Separate energy meters:** Five built-in Homey devices monitor electricity consumption for Heating, Cooling, Hot Water, Boost and Standby. Each provides live power (W) and cumulative energy (kWh). - **Configurable power measurement:** Select any compatible Homey power meter, use automatic detection or use the heat pump’s internal power measurement. - **Energy cost tracking:** Calculates electricity costs for each operating mode using the actual electricity prices at the time of consumption. - **Boiler capacity calculations:** Optionally enter the boiler volume in litres to estimate stored thermal energy and theoretically available mixed hot water. - **Building thermal monitoring:** Records heating cycles, indoor and outdoor temperatures, electricity consumption, temperature overshoot after heating stops, and passive house cooling rates. This data will be used for future predictive heating optimization. Currently monitoring only. - **Thermostat control:** View and adjust indoor and domestic hot water temperature setpoints directly from supported Homey widgets. - **Four interactive widgets:** Heat Pump, Home, Hot Water and Home Data, featuring live measurements, system visualization, energy information and heating schedules. Supports light/dark themes. - **Diagnostics and history:** Detailed system status, historical heating data, monitoring statistics and JSON export for further analysis. ### The goal The aim is to make the heat pump more intelligent by learning from its actual behaviour, shifting energy consumption to cheaper periods and providing detailed insight into where electricity is being used. **Current focus:** Smart hot water optimization and monitoring. **Future development:** Predictive space heating control based on the building’s thermal inertia, outside temperature and historical heating behaviour. The app runs locally on Homey Pro, while the Eplucon integration and external electricity price providers may require internet access. ---

Thank you for the new app. Will try it out. Was wondering if you could also add so control (THEN) cards for room temperature and hotwater setpoints as part of an advanced flow. Since we also have an in-series hotfill boiler for energy dumping and hot water capacity, that might suit us better. Chrs. ---

Thanks for the suggestion! 👍 I’ll add two new **THEN action cards** in the next version of Heatpump Smart Control: - **Set room temperature setpoint** (heating/cooling) - **Set hot water temperature setpoint** Both will use the existing Eplucon control logic, including validation and physical setpoint confirmation. This will allow you to control both setpoints directly from Advanced Flows, for example to make better use of surplus solar energy. I’ll post an update here when the new version is available! ---

Thank you. I do see the Cards appearing. But still an issue that hot water setpoints change but room temperatures not. Room temperature setpoints change in the app in Homey, but not in the Eplucon portal nor in the WP control and Eplucon Touch. Any idea? Have a th-TOUCH (Eplucon: ST-350 (v.1.0.92)). ---

Is this problem only when you set the temperature via a flow? Can you set the temperature via the widgets or in the device? Keep in mind, setting the temperatures will take a few seconds to send and also to read back and confirm. ---

Kenny\_S, tried a couple things. It does work from the flow and widget. But it errors on values when not matching the 0.5 degC increments… Possible to reduce to 0.1 degC increments? 0.5 degC are rather large steps. ---

Hi, First of all, thank you for developing the Heatpump Smart Control app. It’s great that my Ecoforest heat pump can now be controlled through Homey Pro. I’d like to share one improvement point. When I have two-factor authentication (2FA) enabled on my Eplucon account, the app can still read data, but writing fails: the write test returns an error. As soon as I disable 2FA on my Eplucon account, everything works as expected, including writing. What I noticed is that I was never asked to enter a 2FA code when logging in through the app. It seems the app doesn’t support 2FA, which probably means the session gets read access but not write access. Would it be possible to add 2FA support, for example by adding a field for the verification code during login? Or, if that isn’t technically feasible, a clear error message or a note in the documentation stating that 2FA must be disabled in order to write? That would save other users a lot of troubleshooting. I’m happy to help with testing or to provide logs if that would be useful. Thanks again, and kind regards, Frank ---

Hi Frank, Thanks for your feedback and for reporting this issue! The reason reading still works is that the app uses the native Eplucon API to retrieve data, while writing setpoints currently goes through the Eplucon web portal. These use different authentication methods, which explains why reading works with 2FA enabled but writing fails. I don’t have 2FA enabled on my own Eplucon account, so I haven’t encountered this issue during development or testing. I’ll investigate how the portal handles 2FA and whether I can add support for it. ---
