Quite potential

Did the weather station, not alledings purchased via Amazon, for a few days in operation.
The same device there under various names vie internet buying, the selling price, however, is in almost all cases the same as the called here, so absolutely low cost.

The outdoor unit is almost completely made of plastic that does not just appear at first glance wertig, over the durability of the material, I can not say anything, but already the weight can not expect too much. For the price but you can not expect a VA-turned parts.
The indoor unit makes a very solid impression, well, the viewing angle of the display could be somewhat larger, but can be read as well as the lighting works useful.
The range of the radio link is very useful to me about 40m through two walls and a tin shed through, a good performance.

What I like very well, is that there are instructions on the net, how to combine the thing with a Raspberry Pi and the readings then integrated on its website. So I as a farmer via Smartphone always the latest trends at a glance. About the way can also be nice graph span.

The integration into the Raspberry Pi takes when one tinkers afloat NEN half, slowly also good NEN whole day and some skill in using computers is also necessary, but it is the combination works quite well.

In my view it is not necessary to have exactly sure readings on point. Whether the humidity now deviates 5% up or down, or the rainfall less plays 1 liter before or after going a role. The trend is important ... falling barometric pressure and wind speed rising from the west with increasing humidity tells me there is rain. Rising air pressure, decreasing precipitation, falling humidity ... it we better.

This makes the device easily.
The fifth star I give not because the plastic and the suboptimal funnel for rainfall detection.
