I am thinking about how I can connect the underfloor heating on the Fibaro. The floor is from the Uponor brand (exactly Uponor Smatrix Base). They provide a module for home automation but only on KNX (also it costs € 1,800) so it is not a option. Then reading the manual I find the following: Uponor actuators Uponor actuators are mounted on top of manifold valves and are operated using either ON / OFF signals or Pulse Amplitude Modulation (PWM) signals. Self balancing The Uponor Smatrix Wave / Wave PLUS base unit can operate the actuator outputs either through on / off signals or via Auto Balance using pulse width modulation (PWM) signals. Balanced Auto is a function in which the system calculates the current energy needs of different rooms, and adapts the output power of each circuit to its length. This assumes that a short circuit could receive 20% while a longer circuit could receive around 60%. Automatic balancing continues throughout the seasons and depending on owners' changing lifestyles and usage patterns, eliminating the need for manual balancing. It allows the soil temperatures to be more homogeneous and reduce the reaction times of the system, with a lower energy consumption than with any conventional activation / deactivation system. From what I understand the actuators that are 24V, are of the PWM type, and is regulated according to the temperature. Looking at the catalog of products for underfloor heating in Z-wave, I only think that 2 modules can work to me the Danfoss HC or the Qubino Flush PWM Thermostat modules. The Danfoss HC: I see it very old but I don't know how work in Fibaro The Qubino Flush PWM Thermostat: I do not know if it works for specific cases and they are discontinuing it. Can someone give me some light on the subject? I attach a picture of the system.
