**Add support for Heliotherm Heat Pump** **Control** - Set the Domestic Hot Water (DHW) temperature. - Increase / decrease setpoint for heating. **Sensor data** - Domestic Hot Water (DHW) temperature - Buffer temperature - Outdoor temperature - Current request: none|cool|heat|dhw - SmartGrid mode: Disabled | Block | Allow - SCOP for Heating - SCOP for DHW - Total weighted SCOP **SCOP calculations** The SCOP (Seasonal COP) is calculated based on the amount of electrical energy used and heat energy generated. The total SCOP is a weighted average of Heating SCOP and DHW SCOP based on the amount of hours run for each. Device settings can be used to enabled / disable smart grid **Flow cards** When smart grid is enabled in the device settings, the heatpump can be given the command to block all heatpump requests or allow heatpump requests using flow card. This can for example be used to only run the heatpump when electricity prices are low. **Flowcard actions** - Allow - Block **Installation** To use this application you need to enable modbus TCP on your Heliotherm heatpump. See [Enabling Modbus TCP for Heliotherm heat pumps with RCG2](https://deltherma.com/techniek/algemeen/domotica) instruction guide how to do this. ---

Hi Jeroen I have installed your app and connected to my Heliotherm heat pump and everything looks great. I get the DHW temp and can also change the setpoint temp. But I don’t get any value under Setpoint Heating. Is there a fix for the Setpoint Heating issue ? Best regards Niels ---

Hi Niels, Can you make a screenshot of the heating setpoint screen? ---

Dear Niels, Did you upload the screenshots correctly? I cannot download them. ---

Hello Jeroen. I am trying to connect my heat pump to the app. I have activated modbus TCP on the heat pump. I have to say that I have a previous version of RCG. The RCG is connected to the home network by wire. When I look at install devices in the Homey app, I find the Heliotherm app. When I click on that, I get to a screen where I can indicate what I am looking for. But I cannot figure out what to enter there. Then I also have the option to click the “Heat Pump” button. When I do that, I get to the following screen that says: This action connects the Heat Pump to the Homey. Then I click on the “Connect” button. After searching for a while, the answer comes: No new devices have been found. And then the car stops. Intuitively, I think it is because the pump is connected by wire. But is that the case? I hope you can help me further. Kind regards, Baltus. ---

Did you follow the instructions on [Domotica](https://deltherma.com/techniek/algemeen/domotica) to enable Modbus over TCP/IP and then restart the heatpump (very important). After you did this successfully the Heliotherm Homey app will find your heatpump and you can add the device. See screenshot below of (Dutch version). ![Screenshot 2025-01-24 at 10.33.37](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/7/97d0b90122d059cccbc9f43617551d9dc6126226.png) ---

Dag Jeroen. Bedankt voor je snelle reactie. Zoals ik al meldde, ik werk met de vorige versie remote control. Daar staat ook een ander server adres in. Ik doe hier wat plaatjes bij zoals bij mij e.e.a er uit ziet. (sorry ik kan als newby maar 1 plaatje per reply toevoegen Met vriendelijke groet, Baltus ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/3/f3d276981c6a0b9848981375009d8010349f097f.jpeg) ---
