Re: OTGW and on/off thermostat

I installed the 4.2 firmware and the gateway responds correctly to the thermostat commands now. Thanks for the quick repair and release!

Re: OTGW and on/off thermostat

Hi,

I receive DP=20 or DP=30 messages when I send the DP=5E command. Would the new firmware solve this issue? I'll be glad to test it. If you need any results from the tests, please let me know what to monitor.

Re: OTGW and on/off thermostat

Hi,

I did not perform all the tests mentioned in this post yet. But my gateway does not seem to respond to signals from my on/off thermostat. Can this be the same problem? What do I need to test if this is the same problem?

Re: No answer from OTGW USB interface

Hi, Good News! I reconnected the boiler and the thermostat again and I see data now in otmonitor. I don't know if I have changed something. Only possible change can be that I reconnected the wires from the boiler and or thermostat to the gateway the other way around. Anyway, thanks for your help! No...

Re: No answer from OTGW USB interface

Thanks for your quick response again! This morning I woke up and it was pretty cold in our home... The thermostat was showing the "heating" icon, but the boiler wasn't burning. So the gateway was somehow preventing the boiler from heating the house. To heat the house I took the gateway out...

Re: No answer from OTGW USB interface

I chose a test "Voltage leves" which gave a response. So I think the USB interface is working. After that I uploaded the newest firmware and tried to contact the gateway with a small bash script from another post: stty -F /dev/ttyUSB0 9600 -icrnl -echo clocal exec 3<> /dev/ttyUSB0 echo -e ...

Re: No answer from OTGW USB interface

Hi, I checked the jumpers and the USB cable pinout. This seems to be as layed out on the instructions. When I perform a reset (otmonitor running and the green plugs visible) I see the following in the log tab: 21:41:08.540399 p Nothing else appears in the log. At the same time this appears in the lo...

No answer from OTGW USB interface

Hi all, I just connected a new assembled OTGW to my boiler, a thermostat and a raspberry running raspbian. As far I can see the OTGW functions as it is supposed to, except I cannot read/write data from / to it. I turned the thermostat so the boiler should turn on. That worked. But in otmonitor I can...
