Our first question to ask: which sensor do you compare with and where is it installed? Temperatures in a room are not constant and even in a couple feet from different points temperatures will be different. Temperatures will be different even if two temperature sensors are located in a few inches (centimeters) from each other.
We use precise digital sensor element inside our sensors - one of the best temperature element in its class (±0.5°C accuracy within a 'normal' range). We do not average or manipulate the values obtained from the sensor element apart from the conversion to Fahrenheits when applicable. We show you the real value and it is precise value you have at that particular point where the sensor is located
. Moreover, the value is very dynamic - you can test this by holding the sensor with your fingers and see the temperature change in just a few seconds. This will be the real value - more real than any other system with a hidden sensor will show you. Most systems with thermostats use averaging algorithms because the temperature at different points in the room is different - near the window or heater, near the floor or ceiling - the temperatures will be different.
Please see this very short Wikipedia article
about room and ambient temperature definitions. If you use iSocket Temperature Sensor Ambient
it will show you ambient temperature - the actual temperature in any particular point it is installed and this will be true temperature in that point.
So, what to do then? As you probably already understand the ambient sensor measures the temperature around the iSocket itself. Very often wall sockets are located under the window next to the radiator - this is the worst place due to the a huge dynamic of temperature changes from the window and the radiator. The iSocket itself also emits heat. You should find a neutral location for iSocket with the ambient temperature sensor. Another options is to use iSocket Temperature Sensor Specific
. This sensor will work exactly as described above and will provide you an accurate temperature at the point where it is installed but the difference is that thanks to the ten feet (3 meters) cable you can place it at a more convenient point away from the iSocket itself and other sources of heat or cold.
Any attempts to "tune" the value of the digital sensor element readings are basically attempts to fake the readings to show them the desirable temperature as there is no such things like "the correct temperature" exist in general. The correct temperature is the one you like to see or trust to. Attempts to correct the correct readings rather than change the installation conditions will only make the situation worse.
However, if you still want this kind of "calibration", then we can do it for you. Let us know how much less or more degrees Celsius
you wish to have from the value you see now and we will "calibrate" the sensor.
