Getting Unknown controller: Function_Custom error in a Custom Function

Mycodo Mycodo Issue/Bug
1

I’ve added one of the examples functions on (/Mycodo/functions/examples/custom_function_generic.py), but when i click in any of the ‘custom_commands’ buttons, it raises the error:

  • ERROR - mycodo.daemon - Unknown controller: Function_Custom

I’ve been working in a Custom Function python code, but it gave me the same ERROR with all the buttons in custom_commands.

I’ve also have a question that can be related to this issue: does the variables in custom_commands, like button_one_value in this example, are passed as a self.button_one_value in the loop code, like the custom_options variables? Because they all return Nonetype for me…

Thanks in advance for your support!!

This was fixed in the yet-to-be released version. You can upgrade to master to test the latest code.

I’ve made this Custom Function to test to test access to variables defined in the UI. Basicaly it displays the variables create in the ‘custom_options’, ‘custom_commands’ and thru the self.set_custom_function and get_custom_function, and show the result in the debug log.

What i’m doing wrong? How do i access the button_one_value?

Does get and set_custom_option() works in Functions?

I’ve even tried to put the .py file in the main function folder but the results where the same…

The Custom Command user inputs are only passed to the function executed by the button. This is the dictionary args_dict in the function that has the same name as the button ID:

Yes, those are available to use in any custom Inputs, Outputs, and Functions you create.

Ok! Very nice! You are a fast supporter, I’ve appreciated that.

I’ve done the upgrade to master branch and all works now. Thanks!

I’ve got another question for you… It Is possible to update the integer_1 field in the Function Configuration UI via the loop() code or ‘custom_commands’ or any other method?

I’m not sure I understand the question. Could you describe what you’re trying to accomplish?

Let me try to show you, because i will only have access to the system in monday to send you screenshots…

if i run the code bellow, if i run button_one(), it sets ‘integer_1’ = ‘button_one_value’ - 1

Activating the function in ‘default_value’ and running button_one(), self.get_…(‘integer_1’) will be equal to 649 and self.get_…('button_one_value) to 650.

If you open the Function Configuration screen (engine icon of the Function) in the localhost>Setup>Functions, it will still be 100.

And if you Deactivate the Function ( I suppose the value should be stored between activations.). Change, for example ‘text_1’ and Save and Activate again, ‘integer_1’ will be 100 again.

And If i remember correctly, the self.get_…(‘button_one_value’) was None after the Reactivation after a save too, but no 100% sure.

I can send you some DEBUG Log monday…

Cheers!

Yes, self.set_custom_option() is how you would modify the variable values of custom_options.

You can see in the following Input a calibration function that changes the stored voltage and pH values in custom_options with buttons set up in custom_commands.

Keep in mind that if you press Save, you will change the value(s) to whatever you have filled in on the UI Configuration. If the module is changing the values in the background, you will need to refresh the page to see what new values the module has set them to. There is no automatic updating of the UI.

Ok!! Thanks for enlighting my doubts. I’ve runned some more tests… (i’m trying to help)

With the following code i got some weird behavior as you can see in the debug log at he end.

It’s basically the same, but i added 2 more ‘custom_options’, ‘integer_2’ (defined at init()) and ‘integer_3’ (defined in the button_one() command)

Am i doing something wrong again? ‘integer_3’ and ‘button_one_value’ disappeared from the ‘custom_options’ after i saved a new ‘integer_1’ value.

I’am running these tests because i’ve saw one post here in the forum saying that was possible to store “static variables” between reboots, but i’m not getting it.

Just to clarify: What I’m trying to do is like a Feed Schedule Function for a Drain-To-Waste hydroponics setup, where the user inputs the Start time, Span, Nº of feeds, Volume to feed, Reservoir volume, etc, and it do everything else for you, controlling Feed and recirculation pump and notificating the volume left in the reservoir with the help pf a Hall Flow meter. And my intention is to share the code here.

It appears values set by set_custom_option() are erased when the configuration is saved. I found the issue and just pushed a fix. I haven’t performed extensive testing, but it appears to now work. If you would like to test, you’ll need to upgrade to the master branch. Please let me know if if resolves your issue or you encounter any other unexpected behavior.
