How to create new plugin/protocol?

[bbking]

Hi guys,

I've found ESPEasy a few weeks ago and it's so great, I instantly got hooked on it!

Now, I was playing around with it and asked myself if I could extend it with a certain type of MQTT message protocol. I'd like to transfer the data over MQTT in a special JSON format. I have the source code of the stable 120 version. Copied _C005.ino to _C010.ino and made the changes to my certain expectations - all compiled well. But I am not sure if my changes were even considered by the compiler, as my new protocol doesn't show up on the config page. The max number of plugins was limited to 16 so I suppose the code will automaticall check _C001 up to _C016?

Code: Select all

#define CPLUGIN_MAX                        16 

Otherwise I haven't found any

Code: Select all

#include

statements and the google/forum search wans't very helpful either (too many search results). Can you please point me where to start/what do I miss?

Also, when I am using the

Code: Select all

#define FEATURE_TIME

, is there a way to get the date, like %sysdate% ?

Thanks a lot in advance!

Cheers

okay, I've found these two pages:
http://www.letscontrolit.com/wiki/index ... Guidelines
http://www.letscontrolit.com/wiki/index ... evelopment

but my questions still remain - can anybody give me a hint on this?
BTW, the plugin should enable the device to connect to public cloud systems like Azure/AWS/SAP HANA/Dr. Watson and so on...

Hi !

I wrote a SD card logging plugin. And I used the given plugins as sample.
So take a look and give it a try. It´s not that complicated.

Have you any specific questions ?

I think, you need to add the new controller to the CONTROLLER_SET_* section in src/define_plugin_sets.h, otherwise the #ifdef USES_C0... will exclude your plugin from being compiles...
The compiler will automatically pick up all .ino files in the directory, but the #ifdef precompiler command might exclude your actual code from compliation.

This is how I made my Venta device plugin work like a charm: https://github.com/kainhofer/ESPEasy/co ... 709de0659d
