OneWire DS2438 thing configuration

Hi,

The onewire bus with my temperature sensors works. I am litte bit stuck with getting my DS2438 working, as I do not understand the documentation. They used to work on my old OH1 instance.
I am at this point:
.things:

Thing ms-tx AirQ [
    	       id="26.655A38020000", 
    	       refresh=60
    	       ] 

.items:
Number AirQ "AirQ Living Raw [%.12f V]" (GroupWohnzimmer) {channel="onewire:ms-tx:owserver:mybridge: AirQ:voltage"}

Any ideas?

It is strongly recommended to use discovery and Paper UI for thing configuration.

Manual Thing configuration can be very error prone. I would try the documented method first.

Maybe you should tell us what is not working. Provide logs.

space looks wrong there.

Thanks for the help. It is no option for me to use a visual editor. Config files are linux standard.

I succeeded in getting the sensors working with the above definition. I did not change anything. My guess is, that it is because only some sensors appear in /mnt/1-wire and disappear again and some others appear again. If you have an idea why this happens, it would be great.

Best,
Florian

I have now a similar problem with the humidity:

Thing ms-tx OneWireGaesteBadLuftfeuchteRaw [ id="26.743F1B010000", refresh=60 ]

Number OneWireGaesteBadLuftfeuchteRaw "Luftfeuchte Gästebad Raw [%.1f %%]" (GroupGaesteBad) {channel="onewire:ms-tx:mybridge:OneWireGaesteBadLuftfeuchteRaw:absolutehumidity"}

2020-01-07 17:32:23.243 [vent.ItemStateChangedEvent] - OneWireGaesteBadLuftfeuchte changed from -18.1875 to -18.4375

I tried “humidity” as well, but I do not get values at around 40%. Any ideas?

What type of humidity sensor do you use? Are you sure it is connected “the standrad way”? What is owfs showing? What is the device id?

I got it working with:

  Thing ms-tx OneWireGaesteBadLuftfeuchteRaw [id="26.743F1B010000", refresh=60,  manualsensor="MS_TH"]  {
          Channels:
              Type temperature-por-res : temperature [
                   ignorepor=true, 
                   resolution="11"
              ]
              Type humidity : humidity [
                     humiditytype = "/humidity"
 
              ]	
	 }
