Request: Protocol Auriol-Wetterstation Z31601A-RX

[Icesory]

I have a WeatherStation with a protocol that i cant understand.

RAW: 988, 1032, 984, 1032, 980, 1036, 980, 1032, 556, 7920, 532, 4124, 544, 4096, 548, 4092, 548, 1988, 544, 1808, 548, 4092, 548, 1896, 544, 1988, 548, 4000, 548, 4096, 544, 4096, 548, 1988, 544, 1804, 548, 4092, 548, 4096, 548, 1984, 548, 1804, 548, 4092, 548, 4096, 544, 1988, 544, 1808, 548, 4092, 548, 1892, 548, 1988, 548, 4000, 548, 4096, 544, 4096, 548, 4184, 548, 4004, 544, 1896, 548, 1896, 544, 1988, 548, 1804, 548, 4092, 548, 4096, 544, 4188, 548, 1800, 548, 1896, 548, 1896, 544, 4116, 592, 16056

I think only the first and the last Data are right. Its look that the station make a interpolation or so.

[Icesory]

This is the station

I have also a excel file where I test some states

[Icesory]

[Icesory]

Solved the humidity but the temperature is strange

[Icesory]

Solved the protocol.

Can pls some one implement this?

Great work. I will add it tomorrow.

[sweetpi]

Good work again, I added it as "weather4" and released a new version of rfcontroljs. If you want to use it with pimatic you need to update to pimatic-homeduino v0.8.21.

[Icesory]

Thanks for your work. I have seen, that the bit mapping was wrong. I used the not sortet buckets but rfcontroljs used the sorted buckets.
