Thanks Gordon that's a huge help.
I did manage to get to a reasonable point by logging temperatures to an array. That was until the array got too large and crashed the Espruino! So now when I get to the max array size I 'unshift' the first value off the array.
Mode appears to work better than median. I will investigate further using your post above.
The noise may be down to the thermistor I am using. I'm using a 10K thermistor with a 10K resistor as the divider all on a small board next to the Espruino.
To test the readings I was using a 10K resistor in place of the thermistor so in theory I should be reading bang on 25°C but it was fluctuating around too much.
The response doesn't need to be super fast so I think some sort of array and average should work okay.
