Do i-sense a hint to look for a less crummy thermostat ?

Hi Schelte,

Thanks for the new version (4.0a6)! I have installed it on my gateway in combination with my Celcia20 Thermostat. The good News is the messages are now without errors, so the less strict timing works well for the Celcia20 as well. I have noticed the IT command is not available any more and the PR=T command as well, which seems to be in line with this.

What doesn't work for me is the manual setpoint override. I see in your overview of new features "Stop sending the Celcia setpoint in DataID 9.", it's unclear to me why you have taken this feature out as it seem I can't control the setpoint anymore. Or do I something wrong?

Hi Bernard,

Sorry for not responding sooner. I only just got the notification mail of your update.

As far as I know, the Celcia20 doesn't look at MsgID 9 for a setpoint override. It looks at MsgID 4 instead. And if someone with a different thermostat used the TR command by accident, it could put their setpoint to its max. Mine would go to 35! So I started sending the correct setpoint in MsgID 9, instead of using the same value the Celcia wants to see in MsgID 4. This was already changed in the first 4.0 alpha firmware version and you reported you did not see any negative impact from it.

A more likely cause of problems with the manual setpoint override is the new auto-detect of Remeha thermostats. The gateway needs to see a Master configuration message (MsgID 2, reporting the thermostat brand), followed by a Master product version message (MsgID 126, indicating the thermostat model) from the thermostat before it knows it's dealing with a Celcia20. These messages are transmitted by the Celcia about once every 6 minutes, but unfortunately in the wrong order. So, after flashing the new firmware, it may take up to 6 minutes until MsgID 2 comes by, and then another 6 minutes for the following MsgID 126.

If you tried your manual override within this time, the gateway will not have applied the special treatment required by the Celcia20. Have you tried this again after the gateway had been running on the new firmware for a while?

You can check if the gateway correctly detected that you are using a Celcia20 by dumping address 0x69 (DP=69). It should report 69=A0 for a Celcia20 (C0 for an iSense, 80 for another Remeha thermostat like the c-Mix, and 00 for a non-Remeha thermostat).

If you don't get A0, let me know. Otherwise, if the manual override doesn't work while you do see A0, can you send me a log where you issue a TT or TC command?

Schelte,

Thanks! I'm sure I did test it indeed within 12 minutes after upgrading the gateway, according your explanation that seems to have caused the problem! it's working now as is should be. DP=69 gives indeed A0 as result.

Hi Schelte,

Thanks for the new version 4.0a6 I have installed it on my gateway in combination with an
intergas Kompact Solo HRE and an Chronotherm Touch Modulation.
Working like a charm, thanks for the new features.

Kind regards,

Folkert

It's nice to just get an appreciative message without any problems or questions once in a while. I'm glad you like the new firmware.

I was just reminded by another thread that this feature was implemented in 4.0a6: The command is GW=R.

Posted: **Thu Aug 29, 2013 10:16 pm**

Today I tested the firmware 4.0a6. This is my equipment:
- Intergas Kombi-Kompakt HRE 28/24 Combi (boiler)
- Honeywell Round Modulation thermostat
Normally I never use the thermostat itself but I use DomitiGa to override the setpoint on demand or with a time schedule. This firmware test was only done with the otmonitor application.

I found that only the monitor mode (GW=0) gives a correct result. In gateway mode (GW=1) the output gets stuck on a random 'T' message followed by an 'error 1' of which the counter increases endlessly.
The current release 3.4 works without any (noticeable) issues.

Apparently some equipment doesn't produce clean transitions between the logical levels of the opentherm signal, but cause the signal to bounce a few times. I guess I will have to reintroduce the IT command to ignore these spurious transitions.

Posted: **Tue Sep 03, 2013 10:05 am**

I also would like to test this version.
Can this version be used to integrate an outside temperature probe to the gateway.
And if so, where can I get the info.

Posted: **Sat Sep 07, 2013 5:47 pm**

Hi all,

I also have the same errors 01 reported by visserej after upgrading to 4.0a6 from 3.4.

Boiler: Hoval TopGas Comfort 15kW
Theromostat: Hoval TopTronic RS-T

This occurs when setting the OTGW in Control (GW=01).

I also have an error 03 that I still need to investigate.

Schelte,

I have found something strange with the PR=G command. It doesn't matter if I have set GW=0 or GW=1, in both cases the result of PR=G is always 00. As far as I see the gateway is always in gateway mode (Reacting on temperature control commands via serial if).

Posted: **Mon Sep 09, 2013 1:46 pm**

Bernard,

Due to the new configurable GPIO pins feature, I changed the meaning of PR=G: It now reports the GPIO pin settings. There is a new PR=M command to request the operating mode of the device. In 4.0a6 this still returns '1' for gateway mode and '0' for monitor mode. While writing this down I realize that doesn't make much sense. So for 4.0a7 I am planning to change that to 'G' for gateway mode and 'M' for monitor mode.

Thanks for reporting this. I will update the web site.

I'm testing my new OTG, first I installed the 'normal' firmware. Everything seems to work normal. (I see log, I see graph ....)

Because I did not see the Return Water Temp, I tried the 4.06 firmware.
After the program, it's not working correctly

(I did a power down/up)

1) The thermostaat shows "Aansluiting fout" (connecting error)
2) the CH starts heating HELP
3) the program shows :

After re-programming the 3.6 firmware, everything is working normal.

I have a Honeywell Chronotherm Vision Modulation and a Daalderop Combipact 24/33

Posted: **Fri Sep 20, 2013 9:45 pm**

I`m also itching to test this firmware....

But first i need to receive the gateway and solder it together

.

I hope it doesn`t take too long, i`m a .NET programmer and want to start writing software for it myself.
My end goal is to replace my thermostat completely (the display is starting to give up

)
