In the Python plugin framework the fastest heartbeat is 1 second.
Is it possible to create an event or heartbeat with a interval of 300 ms for polling.

I've tried to solve it with a threading.Timer but this is working in a standalone Python program outside Domoticz but not inside Domoticz.

Dnpwwo, many thanks for your reply on this topic (and PM).

The defaults of the serialport are:
- Parity = NONE
- Stopbits = 1
- Charactersize = 8
- Flowcontrol = NONE

Lucky for me this is what I need, so I don't need to change it.


bool CPluginTransportSerial::handleConnect()
{
try
{
if ...

Thanks again zak45.

Your example makes it possible to define the baudrate in the hardware GUI of domoticz.
But I am searching for a way to define the parity and the number of stopbits.

In the python plugin framework the port and the baudrate can be set with:

Domoticz.Transport("Serial", PORT ...

Thanks zak45.
The example in my first post was pyserial code and this is working in a standalone python program.

In the plugin framework you're bound to the given structure.

def onStart():
Domoticz.Transport("Serial", Parameters["SerialPort"], 9600)
Domoticz.Connect()
return

The question is ...

in the python plugin framework it's possible to set the serialport and the baudrate with:

Domoticz.Transport("Serial", Parameters["SerialPort"], 19200)

Is it also possible to change other serial parameters like:

ser = serial.Serial(
port='/dev/pts/81',
baudrate=19200,
parity=serial.PARITY_NONE ...
