Cannot install on CCGX with Venus v3.14

[rrroonn]

Hi, is this a known problem?

When I run the install script (current version downloaded today), the system hangs and then eventually reboots:

I tried this a few times with same result so decided to exit the do-loop.

I am using a CCGX for this testing as I have had bad outcomes trying things on my prod system which is a Cerbo-GX. I learn eventually.

I am wondering if the CCGX doesn't have enough space to install and build?

From my own personal experience I think it's the limited CPU and memory that causes this. I had the same problem on my own CCGX and I was able to trace the problem in the system logs. I can't remember the exact error message but it was something about low on resources and an automatic reboot was triggered. It only happens during install of the dependencies not at run time.

I also experienced same problem when I added 4 ruuvi tags to my CCGX which also made it very unstable, so it's not just a problem caused by the driver.

I think, due to lack of system resources, I am going to have to declare that CCGX is unsupported from now on.

I have just replaced my CCGX with an Ekrano. If you want a test system, your best option is a raspberry pi.

Ok, thank you. Maybe worthwhile noting this non-compatibility prominently somewhere.

I look forward to testing your creation as it may be the beezneez for some integrations I would like to do. Thanks for your efforts and for sharing.

I've been back and forth on CCGX from the start as that was the device I had. At one point I had a separate setup script for CCGX. But since the majority of people using this driver on Cerbo and Raspberry Pi (and now Ekrano) I shall make it clear in the Readme that this is not suitable for CCGX.

No problems installing on a Pi3B+ - and seems to work as described just testing with MQTT Explorer. Now the fun begins.

thanks again,

Ron
