I have an Acurite with outdoor sensor that I got as a gift. The indoor is right on, but the outdoor temp is 6-7 degrees LOW based on comparisons with multiple sources including another wired thermometer to the outside, also in the shade. That one always reads exact to my various other sources. It's just annoying and realize I should just replace it but Ive been looking for a weather station that gives me wind speed and direction and something of higher quality but not over 300 to 400$.

make sure your sensors are exactly in the same place and shielded from
the wind/sun etc when you compare.
It's noon.
Front sensor reads 34F
Side sensor reads 42F
Back sensor reads 38F
all are in the shade.
If I put them all in the same place at night,
they read within a degree of each other.

I have an Acurite remote thermometer. The clock loses about half
a minute per day. Looks like we agree they're crap.

Make darn sure you have a place to mount your weather station.
I got one on a whim at a garage sale cuz it was free.
Got it home and started looking where I'd mount it.
Turns that there's enough shadow from trees along the back
to block a significant portion of the rain.
And all the swirling from the trees made the wind speed
and direction just random numbers.
Glad I didn't pay $400 for it.
