The Samsung EHS Wi-Fi Kit 2.0 (MIM-H04EN) is a wireless connectivity accessory that adds SmartThings remote monitoring and control to compatible Samsung EHS heat pumps and air conditioning systems. Once installed and connected to the home WiFi network, the heating system becomes accessible from anywhere via the Samsung SmartThings app on iOS and Android. Control includes remote on/off, operating mode changes, temperature adjustment, start/stop scheduling, energy-use monitoring and error identification. The MIM-H04EN is the correct WiFi accessory for the Samsung EHS Mono HT Quiet R32 (8 kW, 12 kW, 14 kW) and the standard Samsung Gen 7 R290 Monobloc (CXYDEK series). The Samsung Integrated Mono Gen 7 R290 (CXYBEK series) has WiFi built in and does not require this kit.

It is not required for the Samsung Integrated Mono Gen 7 R290 (CXYBEK), which has built-in WiFi. Always confirm compatibility with your specific heat pump model number before ordering. Key Features SmartThings Remote Control — On/Off, Mode, Temperature from Anywhere Once connected to your home WiFi and Samsung account, the SmartThings app (available on iOS and Android) gives you complete remote control of the heat pump: turn it on or off, change the operating mode (heating/cooling/DHW), and adjust temperature setpoints from anywhere with an internet connection. This eliminates the need to physically access the controller for routine adjustments — particularly useful for second homes, rental properties, or when returning home after a period away. SmartThings appiOS and AndroidRemote on/off, mode, temp Energy Monitoring — Daily, Weekly and Monthly at a Glance The SmartThings app displays the heat pump’s energy consumption in daily, weekly and monthly views. This allows homeowners to track their electricity usage in real time, identify seasonal patterns, and verify that the system is operating efficiently. Monitoring is particularly useful after commissioning — tracking actual kWh consumption against the installer’s modelled figures confirms whether the system has been correctly sized and set up. Daily/weekly/monthly energy dataReal-time consumption Scheduling — Start/Stop Timers from the App Programme start and stop times remotely from the SmartThings app. This allows timed heating schedules to be adjusted without visiting the heat pump’s physical controller — useful for tenants, for working around changing daily routines, or for optimising heating schedules around tariff rate changes (e.g. extending morning heating during cold snaps). Remote schedule programmingStart/stop timers Error Identification and Status Monitoring The app displays the current operating status of the heat pump: leaving water temperature, operating mode, and any active error codes. If a fault occurs, the app shows the error code immediately, allowing the homeowner to check the code against the manual or pass it to the installer for remote diagnosis. Installers using Samsung EHS Cloud services can use the WiFi connection for remote diagnostics without a site visit.

No. The heat pump operates fully without the WiFi kit. The MIM-H04EN adds remote monitoring and control via the SmartThings app; without it, the heat pump is controlled locally via its wired controller only. If you have a Samsung Integrated Mono Gen 7 R290 (CXYBEK series), WiFi is already built in and this kit is not required. Is this kit compatible with the Samsung HT Quiet R32 heat pump? Yes. The MIM-H04EN is the correct Wi-Fi accessory for the Samsung EHS Mono HT Quiet R32 (AE080BXYDEG/EU, AE120BXYDEG/EU, AE140BXYDEG/EU and their 3-phase equivalents). It connects to the NASA communication bus on the heat pump and provides SmartThings remote access. Do I need a Samsung account to use SmartThings? Yes. A Samsung account is required to log into the SmartThings app. Creating a Samsung account is free. A Wi-Fi network (2.4 GHz band) at the property is also required to connect the MIM-H04EN. Once set up, you can access the heat pump from any device and location with the SmartThings app installed and an internet connection. Can my installer use the WiFi connection for remote diagnostics? Yes. Samsung-registered EHS installers can access the system remotely through Samsung’s EHS Cloud services when the MIM-H04EN is installed and connected. This enables remote fault diagnosis, parameter checking and OTA firmware updates without a site visit. Ask your installer whether they use EHS Cloud and can provide remote monitoring as part of their aftercare service.
