@Korina The two time series are shifted by one hour because the stations are in different time zones: the value at time H in 1f06c9a6f matches time H+1 in f06c9a6f. But apart from that they are identical, to convince you have a look at the original netatmo data coming from Salford:

And compare it with the data shown on windy:

Clearly they are not the same, but if you compare the latter with f06c9a6f (shifted by one hour) they are the same.

I've now deleted and recreated the station, we can see in 24 hours if this resolved the problem...

@Korina Hi Korina, it is absolutely clear now that the data for 1f06c9a6f is not correct: on Sunday 16th it ranged from 7º to 14º on my netatmo station, but it ranges from 14º to 18º on windy. On the other side the 0f06c9a6f data did range from 14º to 18º on Sunday, showing that this data is simply duplicated on both stations.

A simple solution for me is to delete the second station, but I think you should investigate this bug because it may mean that incorrect data can be shown in other places.

@Korina Hi Korina, sorry they do report the same data, see the comparison of the two time courses since Tuesday 11th. For example minimum temperature on Wednesday 12th shows 7º in both places, but my own data shows it was 7º in Sarreguemines and 9º in Salford.

@Korina Yes I created 2 separate stations, the IDs are f06c9a6f and 1f06c9a6f

Re : Netatmo
Hi, I have the same issue, I have two Netatmo stations in different locations, they are both shown on the map but the data from the first station is shown in both places. How can I associate each dataset with the correct station?
