I tried to look it up, it’s radio output, solar powered, 868.3 MHz but no hint of much else on the German manufacturer’s website. So the problem is one of finding the type of transmission and protocol, and then writing software to decode it. And it only transmits every 7 mins, so you need to be quick!
The manual says 0.3 - 50 m/s with 0.1 m/s resolution, and direction in 16 steps (22½°)
I think that has a magnet and reed switch inside (I’ll try to confirm later), if so, you need pulse counting software and a means of calibrating it.
You might be wrong there, I think that’s the one I have and it’s about 6 years old, having seized up once, and freed by a quick twiddle and the application of a squirt of silicone grease with PTFE sprayed on the top bearing (the cap and cups pull off the shaft).
I can’t confirm the reed switch - it’s raining. But it’s not likely to be much else considering the price and power requirements (2 × AA batteries seem to last about 2 years in the transmitter).
It looks like this is the same common anemometer, and the author provides some python code and a link to a datasheet that has the calibrated speed? http://mile-end.co.uk/blog/?p=56
Sorry, bumping an old thread but nothing more recent and the question is the same.
I have a broken weather station (Maplin) and ideally want something simpler (wind speed and direction only) which will send out MQTT over WiFi or low powered radio which I can link into my monitoring system. Needs to have solar power as it’s a tricky location to reach easily.
Could build a kit but would prefer something that just works from the box.
In that you are not getting data from it showing on the base station? You may find that it is still sending the data just the base station has stopped receiving it (happened to me).
There are other weather stations out there and if they are 433 then it is possible the rtl_433 will be able to decode it. It is then straightforward to set up a service on a Pi to send the data to an MQTT Broker.
