The Homely Smart Controller (Hub + Node + Samsung Modbus) is a complete optimisation kit for Samsung air‑source heat pumps, combining the Homely Hub, a wireless Node and the Samsung Modbus interface (MIM‑B19N). It gives Homely direct digital control of Samsung heat pumps for deeper optimisation, lower running costs and full remote monitoring.
What’s Included
-
Homely Hub – central smart controller that connects to the internet, the Homely cloud platform and the Homely app, running all optimisation and scheduling.
-
Homely Node – on‑system interface that exchanges data and control signals between the Hub and the Samsung heat pump via Modbus.
-
Samsung Modbus interface (MIM‑B19N) – dedicated Samsung Modbus adaptor that enables two‑way digital communication with the ASHP for advanced control and monitoring.
Samsung‑Specific Functionality
-
Native Modbus integration – Homely can read key operating data and write control set‑points directly to Samsung EHS units through the MIM‑B19N interface.
-
Fixed‑speed pump note – for systems using a fixed‑speed circulation pump with a Samsung ASHP, a RELPOL relay such as R15:2012‑23‑5239‑WTL is recommended for correct interfacing.
-
Brand‑specific kit – this Samsung Modbus bundle is required for Samsung heat pumps; other supported brands such as Riello and Bosch use the standard Hub + Node kit without Modbus.
Key Benefits
-
Simple installation – automatic weather compensation curves eliminate manual curve setup, speeding up commissioning and reducing configuration errors.
-
Up to around 31% cheaper running costs – independent testing at Salford University’s Energy House Labs shows Homely optimisation can significantly cut heat pump bills compared with basic controls.
-
Remote monitoring with Connect / Connect Pro – view live and historic data, check system status and adjust key parameters over the air to reduce call‑outs and keep systems optimised.
-
Wide compatibility – designed specifically for heat pumps and compatible with a wide range of Samsung EHS models via the MIM‑B19N interface.
ECO4 & Commercial Advantages
-
ECO4 Innovation Measure “034” – Homely is approved as an ECO4 Innovation Measure, providing a 25% uplift to the controls portion of the Partial Project Score without affecting SAP.
-
Stronger customer proposition – lower, more predictable running costs help bring Samsung heat pump bills in line with or below those of a gas boiler, making ROI discussions easier.
-
Fewer call‑backs – smart optimisation plus powerful remote diagnostics reduce post‑installation adjustments and site visits.
Installer Process & Best Practice
-
Register as a Homely installer to access training, documentation and the Connect / Connect Pro platform, then order the Samsung kit for relevant projects.
-
Fit and configure the MIM‑B19N module on the Samsung ASHP following Samsung’s Modbus instructions, then install and wire the Hub and Node as per Homely guidance.
-
Commission via the Homely Installer App, confirm communication with the heat pump, and use Connect Pro to monitor performance and fine‑tune remotely over the life of the system.
