otlog ATAG

Postby mmaz » Wed May 15, 2019 10:54 pm

Dear all,
I am looking for someone who has an otlog of the first messages exchanged between thermostat and ATAG boiler.
I have an ATAG boiler model Q15S, which supports z-ready protocol (opentherm by ATAG) but it is not present inside the compatibility matrix (http://otgw.tclcode.com/matrix.cgi#boilers).
I have no thermostat and I am guessing if the boiler needs some special commands before starting to reply correctly.
I built my own interface attached to an esp8266 and I got always "DATA-INVALID" or "UNKNOWN-DATAID" from boiler.
For instance:

TX: 0x00000000
RX: 0x60000000

TX: 0x80020000
RX: 0x70020000

TX: 0x00030000
RX: 0x60030000

TX: 0x80190000
RX: 0xe0190000

TX: 0x00390000
RX: 0x60390000

TX: 0x80380000
RX: 0xe0380000

Thanks in advance for any help.
