Why does VERA show a different temperature reading to Secure Thermostat?

Question

Why does VERA show a different temperature reading to Secure Thermostat?

Answer

Under some circumstances the Secure Thermostat SRT321 LCD can display a different temperature reading than VERA.

This is actually just a rounding error.

Let’s say the real temperature is 25.5 ºC - while the SRT321 will most likely display a reading of 25ºC (rounding down) VERA will display it as 26ºC (rounding up)
