Hi,
I am having a problem with my domotiga 1.0.015 box. I connected opentherm but when i start the interface i get the following in my log
2014/07/05 12:24:34 [OpenTherm] Received status message: B40000200
2014/07/05 12:24:34 [OpenTherm] - status = Flame off
2014/07/05 12:24:34 [OpenTherm] Received 'SE' response: The command contained an unexpected character or was incomplete.

2014/07/05 12:24:35 [OpenTherm] Gateway is not responding.
So it looks like it is working and then i get a gateway is not responding msg.
What could be the issue?
OpenTherm gateway not responding

Re: OpenTherm gateway not responding
The 'SE' response means the gateway received a command it didn't understand. Either Domotiga is sending a wrong command, or there was some garbage on the serial line before Domotiga started. It really should try more than once to send a command, especially the first command. Does this happen every time?
If I read the Domotiga source code correctly, the first command it sends is PR=A. That should work. But just to be sure, have you tried to issue the same command to the gateway with otmonitor?
