How can we get the output from a python file which is run not using exec node from the editor into NodeRED ?

there are MQTT libraries for python, so MQTT is one option

@ukmoose anything else using, stdout ?

output to tcp/udp port and listen for the port in NR or write to a file and read the file in NR ?

[image] ALOKA1432: which is run not using exec node from the editor into NodeRED ? Have you figured out yet why it doesn’t run?

@afelix Hey see the code can be executed from the NodeRED editor easily. The requirement is to run when it is required. The whole system is a combination of python script's output and processing it in NodeRED.

@bakman2 I will try it out.Thanks.

@afelix Like which node ? can you suggest me ?

That fully depends on the conditions on when to execute those. Which would be helpful if you explained those. You can use a switch node to branch a flow depending on conditions, inject/trigger/delay nodes for time based execution/repeated action. For repeated execution following a time schedule you …

@afelix I think you didn't understand my concern fully. The python program runs whenever a user calls it. So then only the should be captured by any nodes. The "stdout" would work when it is run using editor but not from the script which is running through any python IDLE .

Sounds like you can indeed call it from an exec node and process it, but have to design your flow in a way that the scripts get called at the moment(s) you want to... which there’s plenty of nodes available to take care of that depending on your needs
