I bought the interface kit with all components and I just assembled for myself.
I should not have any USB communication problems since I can change firmware and see diagnostics with diagnostic firmware installed on the PIC
My thermostat is Brahma OT11, my boiler is "Emmeti Althea S - I do not know who is the real brand..."
I read the troubleshooting page and I can see some data (such as room temperature, room setpoint, max ch water setpoint, dhw setpoint) only in monitor mode, but still getting lots of Errors 03 in the log window.
If I power off and power on again the gateway I do not get any connection with thermostat, because the interface starts always in Gateway mode.
The only way to get it connected the the boiler is to launch otmonitor and set the inteface to Monitor mode.
If I download the diagnostic firmware the thermostat connects to the boiler in a very short time, and I can see messages if I make tests.
Some tests I made:
Test 5 with all connected:
Code: Select all
Enter test number: 5
Thermostat: 0.69, 1.02, 2.36
Boiler: 0.00, 1.75, 2.08

If I make Test 3 (Bit timing Boiler) i get lots of errors 01 and 03 and some time data such as: Boiler water temperature, Relative modulation level, and some others.
Is there anyway to send you the diagnostic window data with labels and red numbers?
Any help or hint to get it working?
Thanks.
