OTGW integration randomly losing data

[rhtenhove]

A few days ago I received a fresh OTGW with a Wemos D1 (for WiFi) and everything prepared (soldered and flashed by nodo shop).

After connecting my devices (had to do this first after setting up wifi, as it would not boot without):

• Remeha Avanta Ace 28c
• Honeywell Round Modulation

And updating:

• gateway.hex from 6.5 to 6.6
• OTGW firmware from 0.10.2 to 0.10.3+e334c42 (incl. LittleFS, for mqtt discovery)

All seemed well, however in Home Assistant I get various warnings and errors (Command PR failed and timeouts) from the Opentherm Gateway integration. I gave it some time, and the log collected quite a lot of these.

At first I also had MQTT enabled, and was checking the web interface, but I understand combining these causes unreliable results. So I disabled MQTT, closed the web interface, power cycled the OTGW, and opened telnet to see what's going on.

The HA logbook is full of the devices switching to unknown and then back on again, and the OTGW thermostat climate entity will lose temperature and setpoint. Automations don't behave well because of all the status changes. In telnet I see several Not processed, received from OTGW messages, but I don't know what these mean. I've added part of the log at the bottom of this issue.

When I had MQTT enabled and the OTGW integration disabled, but the integrated web interface shown, the web interface would also randomly be lacking data, as well as MQTT showing null for (nearly) all sensors before both would start slowly repopulating again, until once again losing all data.

Given that there seemed little that could have gone wrong (it was mostly plug and play), I'm not sure where to look now for what's misbehaving. The OTGW has internet, dns, ntp, and access to the world if need be, no limitations there.

When it is working, it works just fine, data is read correctly, states are correctly changed (both thermostat and boiler). However randomly it will go bananas, and I can't relate this to anything.

Any ideas? 🙏

Hi @rhtenhove
Thanks for reporting. The logs you share show that you are using the legacy integration, using the serial over network connection. The legacy support in my firmware is just that, it supports the old serial over network option of using HA integration. However I build the firmware initially to make it more reliable, so using MQTT and auto discovery.

So turn off the Native HA integration of the OTGW component, thus stop using the serial over network integration. And then just use the MQTT option. Using both serial and MQTT at the same time seems to give you problems, so try stop using the "serial integration" to find out if it is more reliable.

Let me know what you find,
Robert

Just after posting this issue I had removed the legacy OTGW integration, and moved everything to MQTT. It functions well when it does, however my logs look like this. The most prominent one is that at 05:59:27 today it became unavailable and stayed as such until I power cycled the device.

unavailable	gaps in timeline

The access point mentioned the device was still connected, and all of the leds on the OTGW blinked as before. The opentherm thermostat also still worked fine to control the central heating. However only the power cycle brought the MQTT device back online.

What provides a clue is that my MQTT broker (HASS Mosquitto Add-on v6.4.1) shows either of these messages when it disconnects:

2025-01-08 21:05:40: Client OTGW disconnected due to malformed packet.

2025-01-11 05:59:27: Client OTGW has exceeded timeout, disconnecting.

Doing another telnet log, I see a not processed from OTGW and right after MQTT breaks.

But again CmdQueue saves the day a little later. Both show malformed packet as the cause.

However still not sure what's going wrong.

[rhtenhove]

To further the investigation, I've done a packet capture, and was "lucky" to receive a malformed packet and a timeout quickly after each other. The problem still persists, and it's quite frustrating since it makes it a lot harder to manage my multiple rooms and TRVs.

The malformed packet shows 3 packets which happened at the same time the Mosquitto logs show the failure. The first 2 appear fine, while the third seems to be unrecovered packet loss? Based on the TCP Previous segment not captured.

The Mosquitto timeout log was shown 25 seconds after this packet was seen in the packet capture. Same thing, TCP Previous segment not captured, however that warning is shown numerous times throughout the full capture, where not all show a retransmission, and at occasions where it does not cause a problem.

This was captured on a Raspberry Pi 5 in the Mosquitto Add-on container of Home Assistant OS using:

tcpdump -i eth0 -w - "(tcp port 1883) and (tcp[24:4]=0x4f544757 and tcp[28:4]=0x2f76616c and tcp[32:4]=0x75652f6f and tcp[36:4  
]=0x7467772d and tcp[40:4]=0x39344239 and tcp[44:4]=0x37453135 and tcp[48:4]=0x43413833)"

The latter is to filter on the topic OTGW/value/otgw-94B97E15CA83 so it only captures packets destined for that topic.

I hope you're able to make cheese out of this 😉 thanks for your help and for making this firmware!

Hello @rhtenhove ,
Similar symptoms with my OTGW setup. Instable HA data, multiple unavailable issues. In the serial log many "processOT (....): Not processed, received from OTGW => (..........) [....]". Also a few times 'Client OTGW disconnected due to malformed packet.' in HA its Mosquitto broker log. One time I even captured a "handleOTGW (1745): Serial Overrun" message in the serial log. The number of those messages even seemed to increase when I, for debug reasons, increased the number of telnet clients peeking around.
So Robert's remarks above in this issue thread https://github.com/rvdbreemen/OTGW-firmware/issues/258#issuecomment-2584715454 "Using both serial and MQTT at the same time seems to give you problems, so try stop using the "serial integration" to find out if it is more reliable." made me disconnect all the telnet sessions (including OTmonitor) and only using MQTT in HA.

edit: !!! ---> NOT true anymore: "Up till now, no malformed MQTT packets and no HA unavailability messages."
Still errors, unfortunately :-(

@rhtenhove , when you have simultaneous MQTT and serial (telnet) session in use, maybe that is the issue too?

[rhtenhove]

I had a similar idea that the ESP8266 was just being overloaded; however I've already disabled all sessions, gave the OTGW a power cycle, and made sure to not open any new session (such as telnet or the webbrowser), even temporarily, to ensure it is only connected to the MQTT broker.

Sadly this has been like that for 8 days and still the problems occurs.

I do see that every day there is a time block of several hours where the problem does not occur, but not the same time block every day. Also not a discernible pattern with people in the house, heat demand, or anything of the sort.

I'm going to try a different wifi channel, see what that does. I had already chosen the least occupied channel here (1), and made sure my zigbee network is on a non overlapping channel (25). But perhaps my neighbours do something odd most of the day, who knows.

[rhtenhove]

I have tried a different channel (6 instead of 1) on my default Ziggo modem. I've also tried a different AP (Asus RT-AC68U). Still the same errors.

Also tried another power supply, one that surely delivers enough and stable juice. No difference :-(

[rhtenhove]

Further attempts which made no difference are:

• Greatly reducing the amount of MQTT messages sent
• Setting the timeout of pubsubclient to the default (15) instead of the set 4
• Using a different board (Wemos D1 mini Pro)

One thing that did change but not improve the behavior was to compile with lwip high bandwidth (,ip=hb2f), as from wireshark there seemed to be a pattern of breaking when a packet crossed the MSS threshold (not always). Now instead of mostly malformed packets, there's now various other errors popping up, including just closing the connection, protocol errors, timeouts.

Still no solution. TCP seems to be having a real hard time here.

Similar issues here. There are days like today where the connection is very unstable.

Similar issues here as well. Fresh out of the box, soldered and flashed by nodo shop, all i did was to configure the wi-fi network.

For me I have no issue in the data I get back from the board.
Given it seems to be split, maybe we can find some 'common' factor between the people that have an issue.

• Nodo Shop Board version.
  ** v2.9
• ESP wemos board version.
  (I have received boards before from tinytronics that had a very slow flash chip (Puya p25q32sh), that caused very odd issues. So maybe it is something like this)
  ** Wemos D1 mini v3.0.0 (T25S32)
• What AP is used.
  ** TP-link Omada TP-Link EAP653
• Uptime of the wemos (I wonder if the wemos resets itself?)
  ** 21 days (was a power cycle I did).

@DaveDavenport
Turns out a bad wifi signal was the culprit in my case.
Relocated the OTGW, now its steady as a rock!
