Remeha Tzerra, Etwist, OTGW, ESP12 (esp8266)

Hello gents, (assuming you are all men),
I've got my Remeha Tzerra togehter with eTwist thermostat for about a month and shortly after the installation I built the OTGW with a wifi bridge with ESP-LINK software. All working reasonably fine although I had to set the VR to 1 in order to get almost NO error messages. I'm gonna replace the the transformer for a heavier one and the 7805 for DC/DC converter as I've read this on multiple threads.
My question is about the eTwist thermostat which to my opinion does not talk open therm. It's connected to a seperate PCB in the connectionbox of the CV next to the OT terminal. (see pic).
This gateway translates the communication from the eTwist to OT I assume.
The problem is the thermostat does not see or get or displays the temp when I submit a TT command from domoticz. The OTGW receives the signal but the thermostat does not display it.
Do I need to buy another thermostat which talks OT directly to the PCB of the CV or has the eTwist a setting like the Isense which I need to set to allow for an external command (override allowed).
Thx in advance
