OTGW random crashes

Post by sygys »

Been using the otgw for a few years now. Last year mostly without any issues but lately i am experiencing random crashes. Both in slave and in master. When this happens the boiler will stay on a CS of 70 and keeps heating the water. it has been a cosy month with temperatures rising in out living room up to 27 degrees when we are not home! With the current gas price this is not something i like.

The strange thing is that in slave mode or even when the thing crashes, normally it will give the control to the thermostat but the last few crashes it stops reacting and does not give the control to the thermostat resulting in the boiler not receiving any more commands and when the CS was 70 it will stay 70. When it crashes the logs on the otmonitor stop. I also have the otgw hooked up to home assistant. In the past the integration would render all entities unavailable when the otgw crashes but now it just shows all the last values but doesnt update them anymore. So there is also no way for me to detect it and warn myself when it happens. Also shutting down the otgw doesnt show in home assistant its unavailable. It would be nice if this is fixed so that when there is no communication HA shows the device is unresponsive.

One more thing worth mentioning is the fact that in the past when the otgw crashed a red light came up on the board to show it was crashed now the green led stops flashing (the one showing there is normal communication) but no red error led is burning.

When removing power from the otgw and plug it back in fixed all the problems for a few days. Im not sure whats happening but i did log the otgw up to the point it stops responding. maybe someone can have a look?

Im not sure how much of the log is needed. I have a txt file of around 14MB (to big to add here)

Im running on version 5.3 (newer versions did not work in the past. it wouldnt recognize my thermostat and the thermostat would show no connection)
PIC: 16F88

If someone needs more log entries please let me know. there are 172.000 lines in there :D

Re: OTGW random crashes

Post by hvxl »

An issue that develops or deteriorates over time without any deliberate changes being made to a system usually indicates a hardware issue. Your log shows nothing special is going on before logging stops.

My first suspicion would be that the power supply or USB cable is going bad. Which hardware version of the OTGW do you have? There were a few versions that were very particular about the power supply and cable being used. I suggest to try using a different power supply and cable.

What do you mean by slave- and master mode? In gateway mode, the OTGW is both master for the boiler and slave to the thermostat. In monitor mode it simply functions as a conduit.

You didn't report the issues you now mention with versions after 5.3. Neither did anyone else. None of the changes that were made to the code after version 5.3 has any relation to detecting a thermostat. The last change in that area went into firmware 5.2.

Re: OTGW random crashes

Post by sygys »

Thanks for the reply and I will look into this. The only other thing I could think of that maybe could cause this is the otgw integration in home assistant but I'm not sure if any changes have been made to the integration in core version 2023.11.x

About slave and master i guess I'm using the wrong terminology. With slave I mean the thermostat is in control and with master the otgw itself. With monitor mode i would guess the otgw not doing much more then passing through the info of the thermostat. Thinking about it, it makes sense this could be a power supply issue. It does seem to happen though when dhw hot water is taken from the boiler. But I have to test this more. The big problem is the fact that I can't just test it and go away for the whole day. If the otgw keeps crashing with the boiler having a setpoint of 70 degrees then it will keep heating until I reset the otgw. And since I can't program it to give me a notification when the sensor becomes unavailable or even put in a smartplug to reset the otgw when it becomes unresponsive this is a high risk procedure of testing what the problem is.

But is it normal that the home assistant otgw integration just shows the last values when the otgw is offline even when you unplug it? I think it would be better to set all sensors to unavailable when the otgw is infact unavailable. Else there is no way in home assistant to check if the otgw is becoming unresponsive.

I'm not sure which version I have below a picture of the device:

This was taken when the otgw was unresponsive. All LED's burning on the photo were the ones that were active.

Re: OTGW random crashes

Post by hvxl »

The OTGW crashes you saw in the past were due to a stack overflow. In that case the PIC would be reset by the watch dog timer. That problem was fixed in firmware 5.3. What you are seeing now looks like something very different.

You have a v2.3 board. It says so, right on the board. That is one of the versions that is quite finicky about its power supply.

I am completely oblivious about home assistant, so I can't tell you what is normal. The opentherm spec mandates that a message must be sent every second. If you can put a check on that, you can power-cycle the OTGW if you haven't seen any messages for a couple of minutes. If this cannot be done in home assistant with the existing OTGW integration, you can open a second connection to the USR-TCP232. By default it allows 4 simultaneous connections. Or you may be able to put a check on the boiler water temperature. When the heating is on, it should produce a regularly changing reading. This is one of the checks that I implemented on my home automation system.

Also, set your thermostat to away mode when you're not at home! Then it should never have to send a 70 degrees CS. At least not with a max relative modulation level above 0%.
