W8681 indoor temperature sensor accuracy

Post by ea5xq »

Hi,

Recently, I got a WATSON W8681 (similar to WH1080 I guess)

I have observed that Indoor temperature is giving 2ºC higher than the real one (compare with other two thermometers)

Is there any way to calibrate it?
otherwise, is it possible to find a replacement of the thermistor? (attached a picture marking in red what I believe is the thermistor)

Thanks in beforehand

That looks more like a crystal to me.

Try this.

Thanks Terry, but I would like to see how to fix it from Hardware more than adjusting the offset in the app

What I am observing (not only with Indoor sensor but also outdoor one) is that the values are not instantaneous but seems to be average so evolution is very slow. On the other hand this morning, external temp sensor seems to not work properly, at the car I got 25C and the W8681 sensor shows 17.5C so not fine ...

It seems that the quality of the station is far from it should regarding its cost (140€), I will have to return it back to the seller if I do not find a properly solution
