Hi all!

I am using running a serial gateway connected to OpenHAB, using the examples provided in the forum. I can switch an array on and off using the OpenHAB Controller.

For a start my question is general in nature because I might not have understood something correctly. When I switch the array from the interface the rule I am using is sending the command and then updating the status in the interface. What I am wondering is, what if something goes wrong and the transmission is dropped or there is a bug so the array doesn't really turn on or off? Is there some way to check for this, only updating the status if the node reports success?

Is this done on the controller or the gateway?

I am getting "ack"'s back on the sensor node for data I send from the node to the gateway but haven't figured out a way for the other direction.

Ok, good ideas, as I am working on a ventilation project I thought I'd query the rpm of the fans as a hardware failsafe.

Regarding the software ack @hek , I am not clear on this, is it up to me to react on not getting an ack or does requesting an ack automatically make sure the message is repeated until it gets trough?
