Hello,

I have a chronotherm 4 connected to my openthermgateway and know the time on the chronotherm is changing several times a day.
Why is this and what can i do to prevent it.

Is someone or something sending bad SC commands to the gateway?

Can you provide a otmonitor log for a period covering such an event?

Well at this time there is nothing connected to the otg so there aren't send any signals from the otg to the thermostate or boiler.
I will hook up a computer to log the data packets.

I am experiencing the same issue.
By chronotherm 4 (CMT8851M100) time is going back to 00:00 regularly.

My setup is this:
Boiler: AWB 3HR23T
Thermostat: Honeywell Chronotherm IV (CMT8851M100)
Opentherm-GW USB interface connected to Raspberry Pi with rasbian and otmonitor(ARM)

otmonitor is setup in relay mode and Domiticz setup at another Pi reads the status via the relay.

I have the logfile enable and sofar i did not see any SC command to set the time (logging enable since a few hours)

But i will continue monitoring/logging and get back

Same question goes for you then: Can you provide a otmonitor log for a period covering such an event?

I have a very similar issue with same model Chronotherm 4 (T8851M1000), the clock does not work well when connected to the Opentherm Gateway. In my case it does not reset fully back to 00:00 but it runs far slower than it should be. After some research I think this log describes the issue:

Looking at the display, the thermostat resets the time to the value received in the Write-Ack message, which is a time with hours/minutes only. So when the clock of the thermostat is at 09:24:50 when sending the message, it receives an ACK with "09:24" in it and will reset the clock to "09:24:00". Then some time later it will send another message, if that other message is less than 1 minute after the previous (as is the case in the log at 09:25:31) then the internal clock will now be 09:24:31 and it will receive another ACK with "09:24" again resetting the thermostat clock to "09:24:00". Which causes the clock in the thermostat to quickly fall behind the correct time.

To confirm this theory I check with the gateway in monitoring mode. In that case the boiler responds with "Unk-DataId" only, and then the thermostat clock keeps counting time correctly.

I think the solution is to adjust the gateway firmware to only send a Write-Ack with time value in case an "SC" command has been received in the last 61 seconds.

I never experienced this behavior when I was using the Chronotherm Modulation (I assume that's what you are referring to, because the Chronotherm 4 is an on/off thermostat). But I mostly used to send the current time to the OTGW. With that method, the clock of the thermostat was accurate to the second after a while.

Looking back at my old logs, I see that my Chronotherm Modulation would send MsgID 20 at intervals of 1 minute, or just slightly longer. I guess that would prevent the issue from ever happening. But as I mentioned, the clock used to be accurate to the second when I sent the time. If the seconds would be reset to 0 upon receiving the response, I would expect that it would have been up to one minute behind.

So, I'm wondering why your Chronotherm Modulation is requesting MsgID 20 at more irregular intervals than mine did. Does something happen that causes it to start its message sequence over? Understandably you filtered the log you provided, but I would really like to take a look at a full log covering this slowing of the clock.

I've created a longer log of about 10 minutes, the time was correct within ~5 seconds at 10:30 when I switched from monitor to gateway mode and it ended up behind by 4 minutes at 10:40. The log below is shortened to stay within the maximum post size of the forum, but here is the full log: https://pastebin.com/GBFBLbMe

One hypothesis would be that it changes the message sequence in response to failed messages, because I also have this: https://www.domoticaforum.eu/viewtopic. ... 804#p97804

I attempted to simulate your situation using the interface firmware. I made a script that generates appropriate response, but skips a couple every now and then, which is what it would also look like to your thermostat. (When the OTGW detects an error in gateway mode, it doesn't send anything to the thermostat.) But after running like that for 3 hours, the clock is still correct. So, either I'm not reproducing the situation accurately enough, or your Chronotherm Modulation behaves different than mine. Maybe it has different firmware. On startup, mine says:

T107E0100 Write-Data Master product version: 1 0

Of course there is no guarantee that information is actually updated with new firmware.

Posted: **Fri Apr 16, 2021 9:51 am**

What is the best way to get that attribute? Pull the plug from the thermostat to the gateway, reconnect it while OpenTherm Monitor is logging, or is there some smarter way to make it send the software version?

It also seems there are different Chronotherm Modulation versions, mine has a sticker on the back with "T8851M1000" maybe yours is a slightly different or updated model?

Posted: **Fri Apr 16, 2021 10:50 pm**

The sticker on my Chronotherm Modulation says: T8851M1000 4T40 AD5C 0837 5.

Pulling the thermostat plug from the gateway for a few seconds would work for getting the thermostat to report its software version again. You can also pull the thermostat off the wall and put it back. I don't know any smarter way to do it.

Posted: **Wed Dec 22, 2021 6:18 pm**

Update on this: I haven't managed to make the thermostat report a software version. But I did manage to find another Chronotherm with the same model (T8851M1000), now connected to the same boiler and gateway. This one does not have the same behavior. When it receives a time input from the gateway it only changes the minutes and just keeps counting the seconds as it was. So it doesn't drift.

So it's very likely that there was either a problem with the thermostat or a bug in the firmware version that was fixed in the one I have now.
