Node-RED nodes for hubitat

That tab of sequences has been disabled. If you double-click on the tab name, you’ll bring up a dialog box that will include the option to enable or disable that tab.


@aaiyar thanks you so much that did fix it and I look at that but missed it.

Incidentally I have a disabled flow called "Trash/Hold" that I move sequences I am replacing or just want to hold on to temporarily into in case I need to bring them back in a hurry.


maybe I am doing something wrong, but I'm getting a strange error that says

msg : string[34]
"[deviceId:2458] undefined deviceId"

I'm trying to pass an argument to a switch, rather than specify it in the node. I'm using numbers 100 and 0 to turn a switch on and off. I have not selected a command in the command node.

It still passes the command and turns the switch on and off, it just throws this error up when it does it.

Could there be something upsteam of the command node that is adding a msg.deviceId property to the message stream? I've had that bite me a dozen times.

I don't think so. the flow I posted is just an inject node and a command node.

How to set an HE global variable using a Node-RED Global Context Variable?

And vice-versa.

Oh I fixed this typo (undefined command instead of undefined deviceId) some days ago (not released), but this message can be triggered if you have an input message without msg.command property

Edit: you can add debug node before the command to see if all messages have command property (maybe there is two messages in a row, with and without this property?)

gotcha - so for a switch is it ok to give a value of 100 or 0 and have it turn on and off?

The issue is that I'm mixing hubitat nodes and lutron nodes. Lutron wants msg.payload and the switches are just values of 100 or 0 as opposed to an on/off string. What I want to do is use a single change node to set both the msg.payload and msg.arguments to the same value and then send that to both node types.

The commands for a "switch" are "on" and "off"... Why would you send it 0 and 100?

EDIT: Oh, I see why in your post. sorry.

No, you should add another change node to convert from 0 and 100 to "off" and "on".

because that is the way lutron works, even in hubitat. The hubitat logs will report a 100 or 0 when a lutron switch is flipped on and off.

so, it seems to actually work to send a 100 or a 0. it just throws this error. I just want to make sure this isn't going to break in the future.

I'm just trying to avoid spaghetti.

Hmmmm... I guess @fblackburn will have to chime in. I'm surprised it works at all... I would have said it would not (I actually think it SHOULD NOT, too as I do not like "implied"/"implicit conversion" functionality outside of string<-->number/boolean - but that's another story).

scratch that. it doesn't work. hubitat was syncing my lights and confusing me.

so, i guess that makes this a feature request!

As long as it is an option, I don't care. I don't want the nodes "guessing" what I meant and converting stuff it shouldn't to another format.

Regardless, for now just use another change node to convert 0/100 to off/on. They're free. :slight_smile:


You would need to create a RM GV connector in Hubitat and then expose the connector device to NR. At that point sending values back and forth is easy, but a specific example would depend on the type of connector.

Basically you would use a change node to set "msg.arguments" to "$globalContext("nr_global_variable") using JSONata. Going the other way would use a change node to set "global.nr_global_variable" to the value of the "msg.payload.value" that emanates from the RM GV connector device.


yeah, i’ve been going through things. I withdraw my request.

its pretty easy to just set a msg.command on at the same time i’m setting a msg.payload to 100. i can do it all in a single change node.



Thank you @aaiyar - you are a star, as always! Much appreciated!


I think there is something wrong with giving a setColor command using the hex color format. injecting #800080 into an RGBW bulb, I get a hue of 63 and I think it should be 83.

For some reason hubitat scales the hue values from 0-100 instead of 0-360. I don't know if this is the issue, but I get weird results when giving a hex command. If I convert to HSL and scale the hue values, then I can get the colors that I want.

Unless specified otherwise by the driver, Hubitat scales hue from 1-100. As indicated in the other thread by @rakeshg, simply convert 1-360 values to 1-100 before passing them along to a Hubitat color bulb.
