Opentherm Gateway Ferroli Blue 5

[JACDutchman]

Hi,

I have a Ferroli blue 5 together with a Ferroli clockthermostat. I installed the Opentherm Gateway and use the USB port as interface.
Unfortunately the OpenTherm Monitor program (as downloaded http://otgw.tclcode.com/otmonitor.html) is not displaying any value.

After some puzzeling I realised that the Opentherm Gateway is delivered with diagnostics utility (vresion 1.0) loaded in the hardware.

I downloaded the gateway.hex (firmware image file) and uploaded this in the Opentherm Gateway. Now it is running and I get the graphs.

The data seem to be ok. This will take some checking to learn how the thermostat is actually working.
