What is my claim to a rain sensor? He measures precipitation, with the price determines the resolution and accuracy. The precipitation sensor of Netatmo has very good for its price range resolution of 0.1 mm per rocker stroke. Even the much more expensive Davis Vantage creates only 0.2 mm. When delivered my precipitation sensor was quite inaccurate what was not due to the lineup. The was horizontally. Since no adjustment of the rocker shock is possible right next to the station, leaving only the calibration via software. Here I have not been calibrated in the operating instructions by adding a defined amount of water, but successive values of Netatmo to the values of my reference rain gauge (200cm² Hellmann) adapted. Now it fits, except during heavy rain. Then the sensor by design (flat small funnel) is overwhelmed. The Netatmo advisable not to operate the precipitation sensor in the winter, I think is a bad joke. The sensor, for lack of heating (not optional), snow is measured only at thaw already unsatisfactory, but no winter operation? Ie when there is frost the plastic funnel gets a crack, there is vinegar with warranty / guarantee. By design, can not be retrofitted with a homemade heater on the rocker of the precipitation sensor, because the funnel is then not mitbeheizt. Since only sensor and heater helps in a self-made outer casing installed.
The fixture with a tripod mount is unusual but solvable. Who installed the sensor on a ball, has the ability to easily establish the horizontal position of the sensor again. If the sensor is not in the horizontal position, the seesaw tilts irregular and the values are not accurate. This should be checked regularly.
The establishment of the sensor in the system was straightforward and the spark gap of 10m + 1 wall presents no problem since.
Somehow the precipitation sensor matches the "rest station". For serious weather recording it is not good to see how much it has rained, it is enough (except in winter). Here the satisfaction depends on the claim.
