A Node-Red Introduction for Hubitat Owners

aaiyar · October 13, 2022, 2:24am

What kind of Hubitat device are you trying to send the data to?

Can you post your flow, so someone can try to debug it?

Finally, can you show what the data looks like in MQTT Explorer?

JasonJoel · October 13, 2022, 2:33am

Post your flow details, I'm not going to just guess what the issue is.

Your debug lists 2 messages. You may not have the change node done right. Even worse 1 if the values is a string, so you will have to do an expression or a function node to parse that back into a number....

I can't get that code to import (see note in next post on why).

My guess looking at the code you exported, though, is that it is in your change block. You need to move/copy the value you want to write down into msg.arguments, as that is where the hubitat node is looking for the value (if you don't know what I mean, look at the online help for the Hubitat command node - input section)...

This change node really doesn't seem to do anything? Looks like it moves msg.payload to msg.payload (aka nothing)?

When you post a flow, you need to mark it as preformated text using the </> icon in the editor. Otherwise, there are characters stripped that make it impossible to import.

Ok, got it to import. The problem is as I said above - your change node.

This doesn't work/do anything.

You need to put the value you want to write to hubitat into msg.arguments. Something like this:

You really don't need to guess at these things, as it is all documented.

Per the online help for the hubitat command node, if you don't specify a static value for arguments in the config of the command node, you must specify it by passing the node a value in msg,arguments on the incoming msg.

Having something in msg.payload does nothing in this case, as the hubitat command node does not use msg.payload for anything (otherwise it would be listed in the INPUTS section of the node help).

Good luck!

VLandrew · October 15, 2022, 1:06am

thanks for you help it worked

JasonJoel · October 15, 2022, 2:56am

Great! Glad to hear it!

VLandrew · October 16, 2022, 1:44am

When the string get sent. is there a way that we can add a character behind the string

example

120 but want it to show 120 V

JasonJoel · October 16, 2022, 1:50am

Can do it with a change node using an expression.

You don't need a 2nd/separate change node, you can do that in the same change node you have as a 2nd entry.

Like this:

Or if you are feeling saucy, you could do both in 1 command:

I am new to node-red. Thank you for this introduction. I have a basic question. I am setting up an RPi that will enable me to interface with some functions (e.g., turning lights on and off) remotely in my motorhome. This RPi to interface with the controls is running node-red in an OS called coachproxy (https://coachproxy.com/). All the flows in node-red have been configured. My question is: Is there a way to interface my Hubitat with this RPi as the node-red server to add automation functions that are lacking with the coachproxy alone? Thank you.

aaiyar · February 14, 2023, 2:46am

I’m a little confused by what you’re asking for.

Do you want to use Hubitat to run automations on devices that are currently only on CoachProxy?

Or do you want to add Hubitat paired devices to Node-Red?
