Hi everyone,
This is my first post to this forum and I wanted to thank Schelte for his incredible work making this gateway as great as it is.
I was very impressed how detailed the documentation is and managed instantly ordering the needed components.
Over the past few days I was building the gateway and it seems to work as expected. I used a Raspberry Pi 3 to run the OTMonitor program and to get the gateway connected to my netwwork.
I am monitoring the behaviour of my equipment for a day now via the web interface of the OTMonitor.
I have a Brötje WGB 2N Boiler and the Brötje RRG which seems to be a Siemens QAA73.
Since I see several Messages in the log that don't get interpreted, (MSG 128, 129, 130), do I have to make a special configuration to the gateway to get them accepted/transferred or is this just normal?
Thanks for any help
Wilhelm

Id’s 0 .. 127 are reserved for OpenTherm pre-defined information, while id’s from 128 .. 255 can be used by manufacturers (members of the association) for test & diagnostic purposes only.
Those id's are specific for the Siemens QAA73 thermostat and unknown.

Re: Newbie Question MSG 129-130
Thanks, yes, I read that and I umderstand it.
I was just wondering, if I have to do something, that OTGW accepts or transmits theese Messages to the other side or if its just transparent for unknown messages.

Re: Newbie Question MSG 129-130
The OTGW transmits those ID's to the other side unless the gateway was instructed otherwise http://otgw.tclcode.com/firmware.html#configuration
For example:
OTmonitor doesn't know these new ID's and doesn't know the data type. You can find out and alter OTmonitor (otmonitor.tcl file) an add a few lines code after line 1960. (I don't know if that does the trick, I am not a developer):
For example:
Code: Select all
UI=Data-ID
Unknown ID - Inform the gateway that the boiler doesn't support the specified Data-ID, even if the boiler doesn't indicate that by returning an Unknown-DataId response. Using this command allows the gateway to send an alternative Data-ID to the boiler instead.
Examples: UI=18, UI=6
Code: Select all
register 90 {u8 nu} "Size of fault buffer V/H"
register 91 {u8 u8} "Fault buffer entry V/H"
register 107 {u8 u8} "Size of fault buffer solar storage"
register 108 {u8 u8} "Fault buffer entry solar storage"
# Class 8: Control of Special Applications
register 7 {f8.8} "Cooling control signal"
register 9 {f8.8} "Remote override room setpoint"
register 14 {f8.8} "Maximum relative modulation level"
register 15 {u8 u8} "Boiler capacity and modulation limits"
register 100 {nu flag8} "Remote override function"
