GX Tank 140 missing in Device List (RPi4 Venus OS 2.80)

I've connected a GX Tank 140 to a Rpi4 4GB (Venus OS 2.80 and 2.81), but can't seem to get it display in the device list and thus not able to set it up.

The device is showing properly in the I/O menu. All 4 outputs are enabled and the the device is also properly registered (see log output). Changing firmware back to 2.80 makes no difference. I should mention that the GX Tank 140 is brand new, so I can't tell if it worked before.

From dmesg:

[    3.650761] cp2112 0003:10C4:EA90.0001: hidraw0: USB HID v1.01 Device [Victron Energy BV GX Tank 140] on usb-0000:01:00.0-1.2/input0

Somehow it does not show up a USB-Serial device. Maybe it should not?

Any ideas how to troubleshoot?

Hi Stefanie, I cant comment on RPi, however on my Cerbo GX the Tank 140 does not show on the Device List either, as you configure in the I/O menu the resulting tank then shows in the Device List, may be useful information for you..

Cheers

Hi Wayne and thanks.

There is no submenu in I/O where I can configure the GX Tank. Only options to enable or disable the 4 input. So maybe there is a difference between a Raspberry Pi and a real GX device.

On the Cerbo mine is exactly the same, as soon as you wire a sensor to the Tank 140, that tank will then display in the Device List and you config the tank from there

Didn't know that this is the requirement to show them in the device list, but I have the sensor (the one I talked about in the other thread) wired to input 3. If that's the condition, then I better check the wiring for better contact in the terminal block.

Edit: sensor wires are properly connected.

Hi @Wayne , this might sound repetitive, then please forgive me:

Are you saying that you don't see anything in the device list unless you have wired a sensor up? What sensor are you using / how is it wired?

It should not be like that, definitively not with a Cerbo GX.

For a raspberrypi I don't know, can be usb power issues.

Hi @mvader (Victron Energy) i just re read my comment and can see it may have caused confusion, as soon as i plugged in the tank 140, yes, 4 generic tanks display in the device list, as soon as i connect a sensor, that input then shows immediately for that tank and can then be configured in the Device List.

Using the Safiery (Australia) pressure (water) tank sensors, also going to be installing their pressure (fuel) sensor on my Genset tank and Ultrasonic tank sensors on grey water as soon as stock arrives..

I checked a GX Tank 140 on my RPI4 and the I/O / Analog inputs menu appeared and showed the GX Tank inputs as soon as I plugged in the GX Tank 140. This is on Venus OS v2.81.

Thanks Kevin. That's what I would expect.

My Pi had a USB Hub Hat installed (external power supply). Today I removed the Hat to make sure it doesn't cause any problems plus I disconnected all other devices from the Pi.

This didn't help either.

Interestingly I can see everything in dbus-spy:

Update on my issues with GX Tank 140 and Raspberry Pi4 v1.2 4GB:

Apparently my Raspberry Pi4 has a problem with the USB ports. Maybe a power problem. Unfortunately, I can't find the exact cause.

I had initially used an active USB hub hat and to rule out that it was the problem I removed the hat and flashed a completely new and clean image. Unfortunately also without success. On the dbus I can see that the GX Tank 140 is connected, but the module does not appear in the overview.

At the same time I also connected an energy meter ET112 via RS485. This works so far, but the connection to the ET112 drops from time to time. This leads me to believe that my Pi 4 really has a problem with its USB ports because there don't seem to be any problems on other Pi 4s. Less power-hungry VE.Direct/USB devices on the other hand did not cause any problems.

However, I don't think it's worth the effort to track down the source of the error.

Both devices work fine on a Raspberry Pi 3 b+. Of course, the same applies to the Cerbo GX.

Thanks everyone for the input.

Hi @Stefanie

If you have the time and opportunity, it would be nice if you could test out the latest images with the latest kernel. 5.10-94

It has some updated drivers for usb and some bluetooth fixes, also patched with some venus-os patches

Based on this git repo https://github.com/nmbath/linux.git served by @Bathnm

Note that there are complete Large images with rootfs, so you do not need to install standard image and then upgrade to large

Imager for most pi's is located here based on the latest venus-os

Will definitely try it next weekend. Wonder if these USB drivers make a difference. I haven't had any problems with Bluetooth so far.

Hi Johnny,

just wanted to let you know that the image is running quite happily on my RPi4 since a couple of hours. I've seen no problems so far. dmesg is showing a error free boot.

Thank you for taking the time to test this out @Stefanie

lennycb johnny-brusevold commented · May 01, 2022 at 07:00 PM

should that solve my problem too?

Had problems with my two RS485 adapters (latest org. Victron).

What I have already noticed is that it works if I change the ModBus ID of the ET112 from 1 to 2 and use the image 2.73.

At 2.80 the PI4 only finds the ET112 and leaves out the JBD BMS.

It's just stupid that the 2.73 JBD and ET112 work, but the Ruuvis don't run (only work from 2.80)

May I ask: will the tank level data also be available in Node-red if you use this gx tank 140 device in combination with Venus os large?

Marcel Marcel commented · Mar 31, 2022 at 06:36 PM

I can answer my own question now. It suddenly dawned to me that I could check Node-red for a "tank" node. And yes....its there. So I assume tank level data is available in Node-red. Nice! Ordered a gx tank 140 and sensor.

Thanks anyway!
