Checked my install log, no I did not
I propably have to do it, with pip3 install command, right?
Timo Furrer
@timofurrer
well, actually the w1thermsensor would do that for you, unless you've set the W1THERMSENSOR_NO_KERNEL_MODULE env variable to 1
you'd have to do sudo modprobe w1-gpio w1-therm
maybe you can run this real quick
und ls the dirs again
mikespolk
@mikespolk
Yes, in a second..
Now:

Timo Furrer
@timofurrer
alright, pretty much the same
can you send me link to the sensor you have
the DS18B20 one
if it's really a DS18B20 sensor (which is supported by w1thermsensor) you should have a different folder layout
In there, a link to manufacturer's webpage: https://www.maximintegrated.com/en.html
Timo Furrer
@timofurrer
I understand like nothing on that page :D
mikespolk
@mikespolk
I think, too, when I was using the owfs library, the folder layout was somewhat more like the ID's that you mentioned earlier
Timo Furrer
@timofurrer
okay
however, those libraries don't write those files
they are all populated by the kernel modules
mikespolk
@mikespolk
OK, understand. As I mentioned, I was thinking to doublecheck once more, by installeing the (Python2 only) owfs library, and seeing if its py demo app would enumerate sensors OK.
Timo Furrer
@timofurrer
yeah, you can certainly try
no tutorial and scripts I've found show the behavior you are seeing
mikespolk
@mikespolk
Does not last for long. Do you have chance to wait for it?
Timo Furrer
@timofurrer
they all have the 28- prefix and have a slave file in it to read the temperature from
Yeah, I might be afk for a while
but I'll be back ;)

Timo Furrer
@timofurrer
have you already set that up on the Pi you have right now?
Like on the same installation?
mikespolk
@mikespolk
yes… installed the owfs library and made modifications, but...
can't find python2 ide on my rpi now.
This is the rpi installation I created two days ago

sorry, quite a newbie with Linux. How to run the owfs demo py app?
mikespolk
@mikespolk
Still doing the owfs install, following the I2C sections install guide now: https://www.abelectronics.co.uk/kb/article/1/i2c--smbus-and-raspbian-linux
mikespolk
@mikespolk
Done, rebooting the rpi now...
mikespolk
@mikespolk
Ran the demoapp and it shows the sensors now:

mikespolk
@mikespolk
So, the sensors should basically exist and be enumerable OK.
To still doublecheck, I tried the w1thermsensor demoapp, and it fails to find the sensors, just like earlier:
image.png
Any ideas for next?
Timo Furrer
@timofurrer
Can you try to ask for the type with owfs ?
the type of the sensor?
You could also try to re-install your pi - taking the latest linux
and ONLY install w1thermsensor, but not the owfs library
mikespolk
@mikespolk
Yes, I will answer soon..
So, the types of my sensors, found with the owfs object "type" property; The other lists as DS18B20, and the other as DS18S20 (though has DS1820 printed in its TO-92 case.
