Python Plugin: WLED

[frustreerMeneer]

If anyone interested, I've made a Python plugin for WLED integration into Domoticz.
It's the first version and still quite beta, but it works for me. (It's my first Python project and first GitHUB repository).
Curious to know if it works for you.
My plugin: https://github.com/frustreermeneer/domoticz-wled-plugin
I'm planning to extend it, to make full use of all WLED features.

WLED allows you to control RGB LEDs with an ESP8266/ESP32 over WiFi.

You got any clue what is wrong?
Probably something i don't understand during installation....

thanks in advance

I think you entered the IP address the wrong way.
Try filling out only 192.168.1.98

It should look like something like this:

Update: changes made in WLED app or WLED web interface or now also reflected in Domoticz.

Realy impressive work you have done!

Lovely project!

I'm getting the follwing error after installing and restart domoticz and add the WLED hardware:

How can i fix this?

[frustreerMeneer]

It seems to miss the requests module.

Maybe you can try to install it?
sudo apt-get install python-requests

Let me know if that works.

[vwtune]

same problem after i did sudo apt-get install python-requests

[vwtune]

Do you have an other solution maybe? I really want to use your plugin

[JohnnySK]

Try to install correct version.
Your domoticz use propably python v 3.5
So you need to install package python3-requests

i made a video installing it, maby it helps some people: https://www.youtube.com/watch?v=umVpBED7hpo

Cool video!
Glad you like my plugin.

Hi,

I try to control my WLED with a Nexa 433 Mhz wall switch. I made a Blocky event handler that turn on WLED - Color & Brightness when I press ON and tour off same WLED when I press OFF on my wall switch.

This works but I get this error:

Code: Select all

2019-11-25 22:52:28.240 Error: (CDevice_update) WLED - Color & Brightness: Failed to parse parameters: 'nValue', 'sValue', 'Image', 'SignalLevel', 'BatteryLevel', 'Options', 'TimedOut', 'Name', 'TypeName', 'Type', 'Subtype', 'Switchtype', 'Used', 'Description', 'Color' or 'SuppressTriggers' expected.
2019-11-25 22:52:28.240 Error: (WLED) 'CDevice_update' failed 'TypeError':'argument 15 must be str, not dict'.

When I try to dim the device by use the blocky set dim % it doesn't work at all. Maybe I'am using wrong device. I havent used RGB lights before with Domoticz.

I think your plugin is a great idea. It only need some fixes.

My plan is to use it as a wake up light in the bedroom and use a wall switch to turn it on and off manualy. I know Aircoookie is working on a sunset effect, but else it schouldn't be that hard to implement the logic in Domoticz. But first, I need to be able to control my WLED device with Blocky.

Keep up the good work!

[Ankan]

By the way, I'am running Domoticz 4.10717

[frustreerMeneer]

You are using the right device.
I've only tried a script with Dzvents.
I'll try with blockly.
Can you post what your script looks like?

[Ankan]

My blocky script is very simple and it looks like this..

Code: Select all

If Button = On
	Set WLED = On
Else if Button = Off
	Set WLED = Off

From time to time I get two other errors also

Code: Select all

Transport is not connected, write directive to 'getWLEDStatusConn' ignored.
No transport, write directive to 'getWLEDStatusConn' ignored.

The dim problem where a limitations in blocky. You can't check dim level in blocky so I have to do it in Python or something else. The idea is to make the wall switch smart. If you press on it toggle dim level if the strip is already on. Off just switch off the strip.

[pablo79]

I would like to thank you for the script.

At the beginning I also had errors, but I installed:

sudo apt-get install python3-requests

and now everything works great.

Thanks so much

I will try to replicate your script to see if i get the same error and hopefully i can fix it then.

Code: Select all

Transport is not connected, write directive to 'getWLEDStatusConn' ignored.
No transport, write directive to 'getWLEDStatusConn' ignored.

This indicates that Domoticz could not reach your WLED installation.

I made the following script in blockly and it works. Maybe it's because you used ON/OFF in stead of Set Level?
