I shouldn't have used port 8080. There's a remote access port listed in the OTGW config screens.

I've now disabled it though because I read some posts about Domoticz killing OTGW by bombarding it with requests. I don't want that to happen here.

hi cyril, i'm using otgw+opi0 several months and i'm very happy with performance.
the only compliant is about otmonitor which hangs frequently and I cannot make it working until I reboot whole device.
is there any way (on armbian) how to monitor otmonitor-ahf and restart it when it stops working?

another issue i have is SSH related - my connection to armbian keeps dropping all the time. sometimes every 3-6 sec. i'm geting message: PuTTy Fatal error: Network error: Software caused connection error. anybody with same issue? is it necessary do make any special tweak on ssh connection?

To check otmonitor is working you can periodically run script like this:
TEST_LOG="$(($(date +%s) - $(date -r /etc/otmonitor/otlog.txt +%s)))"
if [ "$TEST_LOG" -lt 300 ]; then
logger "LOG OK"
logger "LOG IS DEAD"
reboot && exit
It reboots OPI if otmonitor log is not changing longer 300 seconds.
About ssh access: I guess you use wireless connection to OPI, because I never faicing with loss connection with OPI. Problem is "Onboard wireless module (XR819) has poor software support so wireless connection issues are expected" (https://www.armbian.com/orange-pi-zero/#kernels-archive) If you want to use wireless, you can download old Armbian image, which has good support of wireless.
