Unknown sensor type 12: TFA 30.5043.01 (Cosy Radar)

[uschindler]

Hi, I have 3 weatherhub sensors, one of those is the Cosy Radar (TFA 30.5043.01, see https://www.tfa-dostmann.de/produkt/digitales-thermo-hygrometer-cosy-radar-30-5043/). It provides temperature and humidity, but also records the average over the last 3 hrs, 24 hrs, 7 days and 30 days. tfrec recognizes the packets from this sensor but cannot decode them.

As requested I have some sample packets (extracted with -DD):

For the last two packets I also have the actual values:

Those are the same (the sensor always sends 2 packets with almost equal contents every 10 minutes), the values here are:

I am not sure where the "Taupunkt" comes from (it's not shown on sensor, looks like it is calculated from the data somehow). So it could be that it's part of the packet.

If you need anything more to enable this sensor or give some guidance to work on chaning the parser, I'd be happy.

Taupunkt ( dew point) can be calculated from temperature and relative humidity - see https://rechneronline.de/barometer/taupunkt.php and http://www.dpcalc.org/

Should be supported now, please check.

Hi, seems to work! Default log output and /bin/echo as application to write values (./tfrec -T 20 -e /bin/echo):

Values correspond with Weatherhub application.

Thanks, I think we can close this. Great work!
