What happens when you press the broadcast button in the MQTT hub settings?

Sorry for the late reply. Been a bit busy.  
Just pushing broadcast in the mqtt hub does exactly what is expected, it triggers a broadcast and updates all selected devices. Nothing strange here.  
As it seems it only happens when homey is rebooted or when my NAS is rebooted.  
Will do some further testing when I have the time to see which exact app and/or docker container causes the strange behavior.

This solved those kind of problems here:

After implementing the above settings (and changing all topics in the dashboard) my problem still exists.  
Yesterday is was able to narrow it down to the application giving the error.  
After restarting the Mosquitto MQTT docker container, all my lights flicker, thermostat is turned off and alarm is activated.  
Creating a debug in Node-red didn’t give any result, because the Mosquitto server is restarting, no topics are received in nodered during the restart.

This conclusion exludes nodered from causing the problem, so i will have to investigate what happens within Homey after a restart of Mosquitto.  
Anyone knows if there any way to create a debug log in Homey?

You can install the app by CLI, and then run  
`homey app run`  
Then you can see the debug output in the cmd screen.

You can add a debug node in Node -red to see all messages coming in. That might be helpful narrowing down the problem:

The Homey MQTT Hub has also a log, but I don’t think it could solve your problem:

The Homey MQTT Client has also a log:

(All in the app settings)

@Peter_Kawa @Satoer Thank you Peter and Michel,  
Already found the log in the mqtt client.  
Will try to narrow down the issue with teh loggings in Homey when i get back from work.

Thanks in advance for the support!

Controlling the color of philips hue lights: It seems like a pain in the ass.  
I have no idea if someone already solved it. I searched through the replies but i was unable to find it so i sat down and tried to come up with a solution.  
I wanted to control 4 color spots that i have. Meaning, turning them on and off but also changing the color. And i found a solution 😀  
This is what i came up with.

Good morning. I haven’t been here for a long time, I gave up continuing with the node-red panel for professional reasons, but I’ve decided to come back.

I have installed node-red on raspberry pi but have run into the following problem.

I manage to connect correctly with MQTT. Through the MQTT Explorer I see all the sensors and devices that I have running on Homey.

I put the test node to transmit the ignition of a philips light. I see in the MQTT explore that the state of the light changes. But the light…does nothing.

I have also tried with a Fibaro actuator. It does exactly the same. In the MQTT explorer you see the state change, but the trigger…does nothing.

Has anyone been through this?

Any idea where the error or failure could be?

Thanks to everyone beforehand.

hello, i have a mac computer at home, and i can’t connect to the rasberry pi. This makes it impossible to install node red. I want to try this now using a windows computer. Only my question if this is successful can I log in and program via the Mac computer? Or does this have to be done every time via the windows computer

Also with a Mac you can connect to a RaspberryPI. Maybe this can help you [https://www.instructables.com/Connect-Raspberry-pi-to-MacOS-or-Linux-using-SSH/](https://www.instructables.com/Connect-Raspberry-pi-to-MacOS-or-Linux-using-SSH/)

Hello @DeepBlueNine, I had a question about your message from Sept 2020 about the glowing ‘on’ button. I understand the function necessary to pass the classportail, but not the “code for the UI Template” and the CSS code. Both those things go in the UI Template node? Or does the button get its own UI Template node? In your previous examples, the CSS code in the UI Template node doesn’t have anywhere written` <div class.... </div>`, only `<style>` and `<script>`.

Basic question is where exactly does `<div class="{msg.cportail}}">{{msg.topic}}</div>` go? And is it a typo to have only one opening bracket on {msg.cportail}}?

Thank you for your CSS code hints for improving the node-red dashboard. Helps me use an old iPad 2 for a display.

It has been a while since I changed anything like this, but did you configure the appropriate return topic?

- onoff READ is this topic (on my homey, with my light): homie/homey-pro-23/light-living-room-design-stand/onoff
- dim READ is this topic: homie/homey-pro-23/light-living-room-design-stand/dim

Please remember to add /set to any update topic.

So for updating the dim level, the topic would be: homie/homey-pro-23/light-living-room-design-stand/dim/set

Maybe it it related to this.
