Anemometer not connected

ko-ryu
My Anomometer needed to change batteries. I did and it reconnected smoothly. But now after two weeks, it stopped. It says, it has no connection. I still see it in the app and has two marks for signal strength. So I unmounted it, and put it closer to the station and deleted it from the home setup, then I did the full reconnect, it worked for two days properly, but it now it tells me again, that it has no connection. I miss a good control or reconnect function. I have no clue, why the anemometer lost connection, and I have no visual sign on the animometer if it‘s connected or not. I still don‘t understand, how base and station communicate… I miss a lot of informations… do they connect by wifi? Why can‘t see a MAC address on my router? If the base is the connection point, why the anemometer stops working suddenly? Is there any advice or support?

    I have a similar problem, my anemometer has frequent data dropouts, the last 3 month I have had 52 data dropouts of more than 1 hour, the longest drop out was for 8h 40m.

    Today it has been out between approx 6 am and 12 pm.
    I can still see the anemometer in the app with a reasonable connection strength.
    Internet has not been out.
    Internet connection for the hub is excellent 1 meter from the router.
    Power has not been out.

    My feeling is that the Netatmo server is not pulling statistics as it should.

    Lasse, I today removed and inspected by Anemometer - and found droplets on the anemometer sensor covers.... So it seems that thing is not sealed anymore.

    Maybe I try to open it, remove maybe some water accumulations and then put into a warm, and dry room.

    After, I will reseal it, as I think the moisture will raise from the cable core into the top: The moisture will condensate in the battery part, by sunlight the battery part will heat up, the moisture will raise, by the cable core like a center channel tube into the top with the electronics, there it condensates at the outer wall during the night times and will slowly accumulate in the sensor covers as lowest point of the top part...
    It's just the center cable core, which will transfer the moisture up into the top causing all the trouble... 
    The center needs to be sealed, too

    So I will seal the bottom lid with silicone, as I will seal up the center core channel with a drop of silicone.

    They need to rethink their Anemometer design, and seal it up way better, otherwise you need to do this process annually - remove the anemometer, open it, let moisture evaporate, reseal and put it back together. 

    It's moisture and if there is bad luck, the moisture has harmed the electronics - and caused a malfunction and or electronic failure by killing some components... this can lead to a full failure, because of death electronics.
    Check if you have moisture in the anemometer
