Feature request - query current state

[TheOriginalMrWolf]

Hi again!

Would it be possible to add a function to query current WLED state (ie - expose the getState() in WledDevice).

Thanks!

Yes, this would be possible. Best thing to do would be a new node that is dedicated to returning the state. Not sure when I'll be able to get to doing this however.

This can easily be retrieved using the standard web request node in NodeRed. Just make a request to http://ipaddress/json/state and you will get everything back. There's no need for a special node to do this.

@danecreekphotography Of course, that's what I do now. However what about the case where someone has many WLEDs - this would significantly & unneccesarily complicate a flow.

I beg you to reconsider - surely something as basic as checking for a parameter in the incoming message to the existing node (say, msg.getState = true) and then simply returning the json already being retrieved by WledDevice/getState() would be trivial for you to implement?

Thanks again for your consideration.

I still don't understand the value of having the wled2 node return this when you can just as easily use a web request node to do it. Perhaps you can post a picture of the flow you are trying to build to help me understand?

I have 16 WLED instances. I'm using node red to synchronise these with HomeKit. Users can use either HomeKit or the WLED app / web page to control the LEDS. This means I need to synchronise from HK -> WLED & WLED -> HK.

Would be great to minimise the number of nodes representing each entity.

Thanks.

That's still doable with just a single web request node, with a switch or function node in front to select which one to retrieve the data for.

The goal of this project was to offer an easy UI for UI-based configuration. For what you are trying to do something like switch/function/web request nodes would work.

@TheOriginalMrWolf Here is a set of Node-Red nodes using the default nodes to get the state. Hope it helps!
