Hi all,
I've got my gateway successfully connected between my thermostat and boiler and am able to see what happend using the OT monitor. Now I would like to connect the gateway to an arduino or a spark core, so I can log the temp, etc online without the need of a computer running 24/7. Although I'm able to receive the data send by the gateway over the serial connection to my arduino, I havent figured out a way to get some more useful info out of the code send, like "B501812F5".I understand the meaning of B and T. But what about the rest.
Is there any "easy" way to extract the Data ID, etc?
Regards, Rutger

Check out the Opentherm specification on what the hex data means. You can find the data ID in the 3rd and 4th digit. In your example that's 0x18 = 24.
