Does set up need to be re-run after a 2.90 Venus OS/CCGX firmware update #16

@freakent Hi Martin, Looks like Victron has released 2.90~3 as a release candidate. Will I need to rerun setup-ccgx.sh if I do a firmware update?

Regards, Gene

No.

edit: that was incorrect assumption by me, YES you do need to run setup again.

At least, I don't think so know, until I (or someone else) test it 😀

The real concern is whether anything has changed in 2.90 to affect compatibility with this driver. We should leave this issue open to track experience with upgrades to 2.90.

@freakent Martin, After updating CCGX to new Firmware 2.90 ~6, and as I kinda anticipated, PIP and yaml are not included in the new firmware images. @40000000627a715f16674484 File "/data/drivers/dbus-mqtt-devices-0.4.1/device_manager.py", line 17, in @40000000627a715f16674484 import yaml @40000000627a715f16674484 ModuleNotFoundError: No module named 'yaml'

I updated to dbus-mqtt-devices-0.5.1 and re-ran setup-ccgx.sh to reinstall pip and yaml successfully.

I then did a bit of cleanup :

  1. deleted "ln -s /data/drivers/dbus-mqtt-devices-0.4.1/bin/service /service/dbus-mqtt-devices" from the rc.local file
  2. deleted the /data/drivers/dbus-mqtt-devices-0.4.1 folder

I can confirm custom names working as well 👍 Successful install on 2.90 ~6

Regards, Gene

Ah ok, I didn't realise that an OS upgrade would clear any additional installed python libraries (such as YAML). Although it does make sense. So you are correct to run the setup script again. I am beginning to wish I hadn't chosen YAML for the config file format!

It might be possible to actually bundle the YAML library into the dbus-Mqtt-devices distribution then all these troubles would go away.
