i ve same problem, the U1WTVS was detect on 1-wire, but i can only see the temperature correctly.
can someone tell me how to set the atributes so i can see the humidity an brightnes?see picture from my fhem Frontent wich was detected
-
@devien Relative Humidity can be calculated from the readings of VAD, VDD and temperature. More info in the documentation http://www.sedtronic.cz/soubory/stranky/Manual-V2-EN.pdf

@tomas, thx 4 first reply.
the documentation doesnt helps, because there are only one formula to insert in a loxone SW, without any informational depend on VAD/VDD
in another post here stay the unica sensor works with fhem, please help us to get it in possible values.
Regards

and another question:
- i ve feed the unipiv1.1 with an industrial power supply 5v
- the unica is direktly conected with only 5 cm wire between
why did the VDD measure only 3,7 Volt?
-
@devien VDD should be about 5V if you have the connection done right.
As in the documentation I posted, the RH can be calculated like this:
RH=(Vad - 0,16 * Vdd) / (Vdd * (0,00654 - (0,00001302 * Temp)))

thx thomas,
i think the Value wich FHEM give as VDD in the Reading (see picture on further post) ma be the Vsense from the lighting sensor. Could it be?
i require that the real VDD on the 1-wire out on the unipi was +5V (i didnt measure this)Now, so u translate I1 , I2 , I3 into Vad , VDD and Temp, i can see the calculating, thanks 4 that.
-
@devien Might be true about the light sensitivity. So then you need to find out how to get the Vsens. That is a question to the fhem forum.
-
i ve measured the Input voltage, 3,7V is correct. why are the 1-wire bus dont provide 5V?
-
@devien Double check what are you measuring. The Vcc pin is 5V: http://unipi.technology/wiki/1Wire_topology
