Has after having used the batteries and the small plastic rocker is in the collected rainwater for measuring assembled (here making sure that the magnet on the measuring unit shows it is necessary to count when the rocker tipping) is a calibration due. In this you have to mind. 100ml water filling into the hopper and count how many times the rocker clacks (ie tipping). The amount of water is then divided "no brainer" by the number of and record the result in the netatmo App. This procedure must be repeated every time the position of the rain sensor is changed. The water must be poured very slowly, otherwise get there by no longer count afterwards. All in all, the device but no problem.
Negative falls on that any mounting hardware missing. Two screws together with dowels would certainly have been the price still in there.
If it then rains and it is not just to be a downpour falls on that yet form the plastic funnel a lot of big drops, the long time refuse in the middle of the drain to the seesaw to flow and partly permanent, to the evaporation, in Funnel remain. Here a kind of lotus effect would have been desirable. Especially with Fisselregen sometimes it takes a long time until the sensor strikes since the droplet build slowly.
Also negatively, the weather station queries the data from only in fairly large intervals. Sometimes the rain is already back pass before the message it rains just arrives in the app. As a note to close the window of the sensor is not suitable, but of course not even thought of.
Positive is that the sensor is fairly low maintenance. Even if times larger objects into the hopper it still works properly and even small dust particles do not clog the device. Thus, it can be placed even in inaccessible places. The battery life is fine. Only the connection range for the base could be a bit better in this regard. It would have been nice if the outside sensor could have served as a kind of relay.
Given the shortcomings listed above, I think the price is not really reasonable. Nevertheless, it is quite nice to look at times the rainfall during the year and so the reliability of the purchase remains then but so just made.
