I see the sensors with ls /sys/bus/w1/devices/ but not in Venus OS

[tobbjo71]

I have managed to install the service and connected two DS18B20-sensors.
i can see the sensors when i do
ls /sys/bus/w1/devices/

But in venus os I only see the rpi temperature. i have rebooted. Please indicate what I can do...

Thanks

Tobias

Sorry, Venus OS 3.66

Raspberry Pi 4B and vcc on pin 1 GND on pin 9 and GPIO26, pin 37 for signal

Hello

Can you post the log?

[tobbjo71]

Sure!
Where do i find it?

[tobbjo71]

this is what I found in /data/log/VenusOS-TemperatureService

Oh, that doesn't look good.
Unfortunately, that doesn't work anymore, as a lot of things have changed.

I haven't been able to adapt the project to the new Victron version 3.6X myself due to time constraints.
I have to upgrade my own system for testing and debugging. I hope to be able to do that one of these days so that it continues to work for everyone.

[tobbjo71]

So if i run an older version it might work as is? 3.55?
I am building up a test system to see that i can incorporate the sensors and relays i envision i will need , so there is no need from my side to use latest venus os version. As far as i know…

[Rikkert-RS]

I'm still on version 3.34 but I think that everything worked without problems until 3.4x or maybe early 3.5

[Rikkert-RS]

But you don't have anything else running that conflicts with pin 26?

[tobbjo71]

Fresh install with nothing installed except what is shown in screenshot above.

Now I have restarted on a fresh 3.34 and I still see the two sensors on

root@raspberrypi4:~# ls /sys/bus/w1/devices/
10-0008021394c9 10-000802139a6d w1_bus_master1

but not in Venus OS

I then changed one of my old sensors in the 10- series to a new chinese sensor and see this:

root@raspberrypi4:/data/log/VenusOS-TemperatureService# ls /sys/bus/w1/devices/
10-000802139a6d 28-000000c7b50f w1_bus_master1

An in Venus OS i see this:

So it seems 10- sensors are not allowed?

maybe I should go back to 3.66 and try with this 28- sensor?

log file with 10- sensors:

Thanks for helping!

Started over on a fresh 3.66:

"inside" is a cheap chinese DS18b20 sensor, in the 28- number range. I held it in my hand to see it go from 24 to 30°C to verify it's working.

So it seems my sensors in the 10- range were the problem, not 3.66 / 3.34?

Hello,

Yes, you're right.
I had overlooked the fact that your sensors are from the 10-series family.
Since there are many different types of 1-wire sensors, I only filtered out the "28" DS18B20 temperature sensors in the code.

Here's an overview
https://interfaceinnovations.org/onewirefamilycodes.html

We can test a Quick Fix to insert the newer ones.
Please send me the contents of one of the sensor files

What kind of sensor do you have exactly?

[Rikkert-RS]

You can try one Change in your Setup directly.

1. per SSH go to the File "/data/VenusOS-TemperatureService/dbus-i2c.py"
2. Change Line 167 "if familyID == '28':" to "if familyID == '28' or familyID == '10':"
3. Keep the correct indentation this is mandatory in Python
4. Restart the Raspberry Pi

After that there are other things that have to fit but you can test it, unfortunately I don't have a "DS18S20" here

[tobbjo71]

Thanks for the effort.

I will try your suggested change.

It is not important to me to get the 10-series sensors going with the venus OS.
They are 20+ year old sensors I've used in another application . I only brought them out because I knew they worked in the other application and some people reported problems using cheap chinese sensors with Venus OS.
In the end I chased my own tail for a while with sensors that were not suitable for this application. You live and learn...

[tobbjo71]

I have tried the change and the 10-series sensor showed up!

It's the 24°C sensor batt temp 103

Thanks a lot!
