Hello again.
I have had better luck with making user pi and installing from that account.
Again, basic emoncms install was error-free. I left the line install_emonhub=true just hoping that even if it does not get installed, the entries for it to appear in emoncms would be ready.
Installing emonhub using the script these errors occurred:

Defaulting to user installation because normal site-packages is not writeable
I “solved” it (maybe) by apt install python3-requests python3-paho-mqtt
Then the systemd issue is solved by changing these:
Requires=rsyslog.service
After=network.target
plus the obligatory sudo systemctl daemon-reload.
Then emonhub will start! And, after adding user pi to the group dialout on the guest CT, and some fiddling with /dev/ttyUSB0 on Proxmox host ( chown 100000:100020 /dev/ttyUSB0 ), and modifying the CT config file on the Proxmox host to end with
lxc.cgroup2.devices.allow: c 188:00 rwm
lxc.mount.entry: /dev/ttyUSB0 dev/ttyUSB0 none bind,optional,create=file
and restarting it of course. YMMV, but this is working for my set up.
Notably, the entry for emonhub does NOT appear in emoncms webconfig settings. I’m not sure if that is expected or not. So I modified the emonhub config file commenting out things I don’t use and adding my emonTx4 with USB connection as directed:
[interfacers]
### Manually added for the emonTx4 unit
[[USB]]
Type = EmonHubOEMInterfacer
[[[init_settings]]]
com_port = /dev/ttyUSB0
com_baud = 115200
[[[runtimesettings]]]
pubchannels = ToEmonCMS,
nodename = emonTx4
when I tail the emonhub.log I see what looks like correct functionality:

(I haven’t connected the CT clamps to anything yet)
The docs say that once this is done I will see the sensors from the emonTx4 automatically populate in the INPUTS area of emoncms webconfig – but I don’t!
Maybe I should take that to a new thread. I did here.
When I look in emoncms ‘System Info’ I see the following services are green and happy:
emonhub
emoncms_mqtt
feedwriter
service-runner
redis-server
mosquitto
demandshaper
and emonPiLCD “not found or not installed”
Please let me know if you have any suggestions and thanks for bearing with me.
