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:
#!/bin/sh
TEST_LOG="$(($(date +%s) - $(date -r /etc/otmonitor/otlog.txt +%s)))"
if [ "$TEST_LOG" -lt 300 ]; then
logger "LOG OK"
else
logger "LOG IS DEAD"
reboot && exit
fi
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.

Obviuosly, your boiler is not in the equipment matrix http://otgw.tclcode.com/matrix.cgi
Your boiler have Opentherm? If yes, you can try to use OTGW board, but nobody can promise what it will work.

girolamicaminetti.it/contrib/uploads/Ma ... 28kW-1.pdf

here its the scheme of connection with boiler and external lcd panel control, i dont know if knowing this connectivity and codes to setup the boiler you can know if works or not with opentherm...

HI,

I did a search on that site for "opentherm" without any results, so I guess its a proprietary protocol.

The only way to know this for sure is to ask the vendor, maybe its on their roadmap

In worst case, you can damage your boiler.

For people who, like me, bought an H5 OrangePi, I got otmonitor working on this device today, in native aarch64 mode:

For those, who considering for use this expansion board. Because of chip shortages Orange Pi Zero H2+ and LTS temporarily unavailable. Please, choose substitute Orange Pi Zero H3 board.

Hi Cyril - very pleased with the board you sent me! Working perfectly with the Orange Pi Zero H3.

Do you have the STL for the enclosure you 3D printed? Can you share it?

I installed the latest armbian (focal) and copied your service script over from the image you provided, then updated otmonitor-ahf to latest 5.1 and it's working perfectly, also updated the gateway hex file to the latest (5.1) which also worked perfectly.

Thanks again!

Hi, Seb! But it's not 3D printed. It's OPIZ enclosure from manufacturer:

Hello everyone, what is the blue part near the four green terminal blocks? If it is a capacitor, what is the value? Or tell me the marking of the part. Thank you.

Всем привет, что за синяя деталь возле четырех контактной колодки зелёной? Если это конденсатор то какой номинал? Или маркировку детали подскажите. Спасибо.
