Hi trying to make running serial plugin on pimatic 9.0.42
get message on sending following data: sutter:4:down

(node:1396) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: First argument must be an int

does anyone know what is the reason for the error mesage

@viktor how did you configure the plugin?

Also, read here how to post code/debug data on this forum;

data on this forum

I intend to use the plugin for communication with a arduino.
i configured a SerialShutterDevice:
Baudrate: 115200
DataBits: 8
Parity: none
stopBits: 1
flowControl :yes

@viktor did you set the serialport? To what? Are you sure that it is correct?

yes of course,
/dev/ttyACM0
the port is working test it with shellexecute execute “echo shutter:4:down>/dev/ttyACM0”

@viktor alrighty, and did you restart pimatic after installing and activating the plugin?

Also, when does it display that error? When you save the settings? When you start Pimatic?

Does pimatic function with this error?

Here the log.
