[HELP] thingsboard gateway modbus-rtu

Hi @KarimSayedAmir,

Thank you for your interest in ThingsBoard IoT gateway.
Please try to make a backup of your configuration, remove the old gateway and install a version 3.4.3.1 it contains minor fixes for logging system and may help with this issue. Let us know about results.

Hi @imbeacon,

thanks a lot for the quick reply. I will check this today and give you feedback.
Have a nice day.

Hi @imbeacon,

actually I am getting this now:

1.)Can this be connected to the Ubuntu 22.04 right management?

2.)Strange thing is that if I am using my own Modbus Lib, i can read the sensor easily.

Have great evening

Hi could solve the first issue:

The installation was done over the deb package.
I created the missing folder:
sudo mkdir -p /var/lib/thingsboard_gateway/logs`

Then i had to add permissions:

sudo chown -R thingsboard_gateway:thingsboard_gateway /var/lib/thingsboard_gateway/logs sudo chmod -R 755 /var/lib/thingsboard_gateway/logs

Now the log looks like this: owipex_adm@owipex:/boot/firmware$ systemctl status thingsboard-gateway

But the sensor is still not reading.
