Something interesting happened last night as the emonhub stopped to resend to emoncms.org. Also local emoncms web interface not working. Did a power off cycle and now systemctl status shows degraded, i.e. failed to start.
Reinstalled ./emonhub.sh and everything is back to normal. Anyhow still the dhcp server is not starting - I guess its not needed.
Using latest SD image with rPi, both orded from shop a couple of weeks ago.
Systemlog tells Mosquitto did not connect ???
