- √ - Heating? Logics or?

[Rasmus7700]

Hello.
Im getting started with the HS.py and SV
I create all my stuff in the smartvisu.conf (items) with a structure like described.

I was wondering, if i want to use the Heating Widget, do i then need to make the control in the logics of the sh.py? If Temp < Setpoint then valve = 1?
Or will the widget do all this for me?

Hi Rasmus

Normally all parameters and values you need for the RTR widget are retrieved via KNX group addresses which are connected either to objects from your room temperature regulator (e.g. current room) or the heating actuator (e.g. valve state).

Only if your actuator doesn't provide certain data you have to determine it via a logic or an eval function.

Hi...Okay, but will the widget act as an room controller and then run in a cycle by default?
My valve is only a bool on/off - but what about the modes? Seems like there's telegrams for that - but isn't thAt normally just a signal to the heating controlled to set a specific set point?

Hi

I think you misunderstand the function of the widget. The widget is just a graphical user interface for a room temperaturee controller. I.e. you can visualize the current status, current temperature etc. and you can change certain values like set temperature, heating mode etc.

But the functional logic to open/close the valve based on current and set temperature is built in a room temperature controller, i.e. a piece of KNX hardware (either a device in a flush mount box in the room or in combination with a separate temperature sensor as part of your heating actuator).

Arhh okay... That makes sense... This means I hAve to make the control inside the logic function, since I need to manually program my heat controller..


Can I make a mind of internal variable, without a KNX address, but only have the function to make a link from smartvisu to the logic?
