Hi All,
I’m currently trying to control my now ageing Nuvo Grand Concerto over RS232 connected directly to my Pi running openhabian.
If i run the below from terminal i can control the Nuvo and also get a reply showing in the openhab log:
Command In Terminal: $ echo -e “*Z6POWER \r\n” > /dev/ttyUSB0
Reply in Log File: 2019-05-06 23:33:50.204 [vent.ItemStateChangedEvent] - NuvoRS232 changed from #ALLOFF to #Z6,ON,SRC2,VOL60,DND0,LOCK0
This means that openhab is actually reading the correct serial port and also leads me to believe that the permissions are in place.
However I am not sure if i would need to create any additional items in the .items file
all i have at the moment is the below:
String NuvoRS232 “NuvoRS232 [%s]” { serial="/dev/ttyUSB0@57600" }
I have created the following button on HabPanel:
but it seems to be doing absolutely nothing apart from writing the below in the log file:
Is there something very obvious i might be missing? I have seen people using rules etc to control serial but to be honest i can’t understand why and if i need rules and a sitemap if all i want to use is HabPanel. Obviously i might be missing something very obvious, so i would appreciate any help
