Philips Button State

Dashboard
1

Hi everyone!!!

I have a Philips Hue with a couple of bulbs installed and Huemagic in NodeRed.

I want to control the bulbs with a button that knows what "state" the bulb is in and then activate (true / false) depending on the state of the bulb.

I explain;

The light works as true (on) or false (off). This needs to be verified. The "hue light" node sends the state of the bulb.
Then I have a light button that will always send true.
Depending on the current state of the light, I want the button to activate otherwise.

Check the light status -> Light: OFF -> Press_button: True -> Light: On
Check the light status -> LightOn -> Press_button: True -> Light Off

Has anyone worked with this?

Thank you.

Greetings

Hi!!!

I have been doing several tests.

I took the @davidcgu example and set it to enable / disable the bulb or group of bulbs. This is done correctly, but I still have problems with the state of the bulb.

Any idea why the button does not change color and icon depending on the state returned by the bulb?

Grateful in advance and sorry for being such a rookie.

Hi!!!

Hello all,
I have installed a hue button via zigbee2mqtt and would now like to be able to display and use this via node red.

The button sends with short press these three commands. with a second short press, the same commands just OFF

Bildschirm­foto 2023-01-18 um 20.34.16880×908 67.6 KB

If you press the button long it sends these commands

Bildschirm­foto 2023-01-18 um 20.34.59
Bildschirm­foto 2023-01-18 um 20.34.59880×460 36.2 KB

the device sends 7x this step down command and then step UP

Can anyone help me with the creation of the flow or has this possibly already used?

6

You have not said what you want the flow to do.

7

Hello,
thank you for your answer.
I want to dim lamps and LED strips.
This is connected via a Demos D2 mini and the dimming takes a Mosfet.

8

Have you built a flow to control the lamps using just inject nodes? If not then do that first. When that is working then you work out how to control it from the button.

9

Hello,
how do i get it to extract only the payload on / off / up / down from debug?

10

If you were to use a Switch Node, you can trap each message individually and route to appropriate actions.

11

Also I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

debug1 is from the hue button
debug2 ist after the function node

I added a few nodes to the flow. Hopefully it helps. My dimmer works.

Hello, very good.
Thanks :slight_smile:
However, have another problem.
I want to use a Hue button. This sends on / off when pressed short and 7x when pressed long:
{"action": "brightness_step_down", "action_step_size":56, "action_transition_time":0.09, "battery":100, "linkquality":184, "update":{"state": "idle"}}

and then 7x:
{"action": "brightness_step_up", "action_step_size":56, "action_transition_time":0.09, "battery":100, "linkquality":176, "update":{"state": "idle"}}

I would now have to convert that to a number to use it in the range note.

can you help me?

this is my current flow:

Hello again,
I have tried it myself and now always get a 0 or 100 as output.
step down I get 7x and then 7x step up.
I need a function that sets the value at step down from 100 to 0 and then at step up from 0 to 100.

let stepSize = 100 / 7;
let step = msg.payload.action;
let brightness = Number(msg.payload.brightness);

if (!isNaN(brightness)) {
    if (step === "brightness_step_down") {
        brightness -= stepSize;
        if (brightness < 0) {
            brightness = 0;
        }
    } else if (step === "brightness_step_up") {
        brightness += stepSize;
        if (brightness > 100) {
            brightness = 100;
        }
    } else {
        brightness = 0;
    }
    msg.payload = brightness;
} else {
    msg.payload = 0;
}

return msg;
