Programming the celcia-20 thermostat (schedules, temperature levels etc) was is one of the things one could do with the original Remeha Gateway.
I this also possible with the DIY gateway, or requires this functionality more than just passing the commandstrings generated by celcia application to the thermostat?

Re: Programming the Celcia 20
It probably uses some proprietary method for that, perhaps similar to the unusual way the setpoint can be changed. If you (or someone else) can log the opentherm traffic between the Remeha gateway and the Celcia while changing the schedule that way, we may be able to reverse-engineer it.

Re: Programming the Celcia 20
Ok, I will try to do that (might take some time to set it up), does that require that the DIY gateway is between the Remeha Gateway and the Celcia, or it doesn't matter since it is a bus architecture?
Re: Programming the Celcia 20
The DIY gateway indeed has to be between the Remeha gateway and the Celcia. The messages we are interested in will very likely not show up on the connection between the Remeha Gateway and the boiler. I would also suggest to put the DIY gateway in monitor mode to prevent it from modifying the communications.
Please note down exactly which programming action you did (including all values) and at what time to make it easier to correlate the actions to the messages seen in the log file. It may also be useful if you allow some time to pass between your actions in case each action results in multiple opentherm messages. You can even send a string (like Action#1, Action#2, etc) to the DIY gateway to mark each action in the log. The gateway will respond with SE, but that's OK.
With every action you do, change only one thing from the previous action. So don't schedule the setpoint to go to 20 on Monday at 9:00 and then another action to change it to 19.6 on Tuesday at 8:20, but do it in steps, e.g.:

Re: Programming the Celcia 20
Yes, the step-by-step makes makes sense., keep in mind that the Celcia works with Temperature levels, so there are commands to set a specific level (I believe 5 in total) to a certain temperature. Once you have done that you provide a time stamp and the associated temperature level.
I will 1st need to find some time to connect the whole stuff and have 2 serial ports available to allow me to talk to both units.

Re: Programming the Celcia 20
Ok, did my 1st test, but the Remeha Gateway doesn't recognize the celcia and I can't read/write the programming values, beyond that normal communications are working fine.
Setup
** Boiler - Remeha GateWay - DIY Gateway - Celcia 20
** DIY gateway in monitor mode
** DIY Gateway running FW gateway-4.0b1
** OT monitor 4.0b3
Trying to read FW versions (using the celcia 20 program), I'm getting the following messages.
When the DIY Gateway is disconnected I'm getting this:
Looking at the difference between 11 and 251, it tuns out that all MSB bits are set to "1", while the Remeha Gateway expects them to be "0":
At this stage I'm not sure what to capture exactly, this is what otmonitor logs when I'm trying to "read" the current program values from Celcia 20 (using the celcia 20 program)
When I disconnect power from the DIY gateway, the Remeha Gateway is able to read all the values from the Celcia 20.
I would say that:
- The bus connection is good
- The DIY gateway is indeed transparent when powered of (unlike the Remeha Gateway; when it's powered down the celcia's display goes blank.)
- The DIY is still injecting some kind of code into the BUS, which confuses the Remeha Gateway.

I would say that:
- The bus connection is good
- The DIY gateway is indeed transparent when powered of (unlike the Remeha Gateway; when it's powered down the celcia's display goes blank.)
- The DIY is still injecting some kind of code into the BUS, which confuses the Remeha Gateway.
Re: Programming the Celcia 20
Something is fishy here. The MasterMemberid is reported by the thermostat via MsgID 2. That message doesn't show up in the log you included, but in other logs I've seen from a Celcia, it indeed normally reports 11. And since the DIY gateway is in monitor mode, it doesn't have a chance to modify the value. The only thing is the thermostat only reports MsgID 2 once every 6 minutes. So maybe you were too quick with your test. Wait until you see MsgID 2 listed on the summary tab of otmonitor.
Also, there is no way opentherm messages can pass through the DIY gateway when it is powered down. You must have been testing something other than you thought.
From this first log it looks like the Celcia is using MsgID's 198 and 200 through 215 to communicate the schedule to the Remeha Gateway. But judging by the errors seen in the log, the information exchange doesn't fully comply with the opentherm specs. That is unfortunate. We may have to resort to the diagnostic firmware to fully figure out what is happening on the line.

Re: Programming the Celcia 20
Yes, you are right:
- I did test it again with the DIY gateway off and it did indeed not pass any messages. Maybe I was too quick in checking the Celcia-20 display.
- The Celcia-20 program now reports the correct id's:
In any case, the DIY gateway is blocking some of the messages: I did put it in monitor mode, but the Celcia-20 program comes back with a read error.
The log shows error 02 and error 03 messages:
When I load the diagnostic firmware in the DIY gateway, I am able to read from the celcia-20 using the Remeha Gateway. I've tried to capture the conversation while reading (had to use the old 3.3 Otmonitor for that to get some logging:
I've no clue whether or not I was able to capture the right sequence, otherwise let me know how to proceed.
Thanks,

Re: Programming the Celcia 20
It's a bit strange that you got an error while reading the schedule with the gateway in monitor mode and it succeeded with the diagnostic software. In both cases the comparators in the PIC are configured to copy their input straight to the output, so the gateway is transparent for opentherm signals.
When you first reported that reading failed, I was afraid the communication also made use of something other than the normal opentherm level signals. But if it works with the diagnostic software, that's good News. I assume the Remeha equipment may just be a bit picky about timings (the opto-couplers in the gateway may introduce slightly asymmetric delays), so you sometimes need a second attempt.
I will take me some time to analyze the bit timings you recorded. The diagnostic firmware only captures one side of the communication. So you will have to perform each action twice, once capturing the thermostat timings and again for the boiler timings. Sorry about that. The gateway just can't report the timings fast enough over the serial connection to be able to do both directions. (To report a bit time of 555 us takes 4167 us at 9600 baud, so you understand the gateway needs the 1s gap between messages to catch up.)

Re: Programming the Celcia 20
Thanks for explaining, I did perform a "read from Celcia" 4 times:
2 * while test 2 was running
2 * while test 3 was running
Attached the log:

Attached the log:
Re: Programming the Celcia 20
Can you also reveal what the result was? That might make it easier to decode the data.

Re: Programming the Celcia 20
Sure, no problem. That is to say, I've attached the screen captures of the 6 screens as well as the .rcp file, which is a binary save of all the settings.

Hi Schelte,
Do you need anything more from me at this stage?
Do you need anything more from me at this stage?
Re: Programming the Celcia 20
No, I just need to find the time to analyze the data. It's a pity they use signals outside the normal opentherm messages. Otherwise things would have been a lot easier.yjb wrote:Do you need anything more from me at this stage?

Re: Programming the Celcia 20
My analysis of the available data seems to indicate that the thermostat first sends a regular opentherm status message (80000200), after 10 ms of idle state followed by 5 times 3.5 ms of logical high separated by 3.5 ms of logical low. Then, after another 10 ms of idle, it sends the requested data. That data looks somewhat like an opentherm message, except that it has more data bytes. Unfortunately I couldn't determine how many. The diagnostic software doesn't capture enough bit transitions to cover the whole thing.
Special firmware will need to be written to investigate further. That will be a lot of work. I don't know when I will have time to do it.
