Does the radiant heat not increase the room temperature, thus affecting the indoor temp sensor? Combining that input with outdoor temperature (and whole weather stations) is totally done. Similarly, floor heating systems measure temperature of the radiating element (floor) and room temperature to decide if they switch heating on or off. I generally combine shutters for large windows in controlling the temperature in my automation too (greenhouse effect). |

Yes but the temperature of the air in your home is only one part of it. The other part is the temperature of the radiant heat.
I always understood that the temperature is measured in the shade, and that the difference between shade/sun on a sunny day can be very significant. A temperature of 22 degrees in the sun would feel like standing in the shade at 30 degrees.
Similarly in your home it could very well be that the air is your house is heated up to 22 degrees by the outside air and radiant heat, but additionally if you're under the radiant sun sitting next to a window it can feel much hotter.
Of course if the temperature meter itself is exposed to the radiant heat, it'll likely measure that directly. But mine for example is mounted under a table in a utility corner and gets virtually no radiant heat. I could mount it next to the window to get exposure to the radiant heat of the sun, but then if I'm sitting further away from the windows in the room I get no radiant heat but the sensor does, and it'll think the room is a lot hotter than the experience I'm having.
