how to handle 2 buttons? like if I have button submit and cancel, I want to use switch node to handle
@ruwindustries 4 күн бұрын
As far as I know, the cancel button just resets the user input and does not output anything. Thus, it is not possible to handle the different actions using a switch because you don't know when the user clicked cancel.

what is msg.enabled? so when you send a boolean payload (converted from msg.enabled) to the button will activate and deactivate it?
@ruwindustries Ай бұрын
Thats correct. If you send “msg.enabled = False” then the user won't be able to use the button.

Brother, you have an excellent video, thanks for the content you upload. One question, how could I change the color of the animation, of the circle and the background of this with the Level type? Putting a name in the properties didn't work for me, so I changed the letters to the general class that each gauge has.

Hi, thank you for watching them - I really appreciate it. There is probably a solution when using tabulator callbacks. Specifically, the cellClick Callback found here: tabulator.info/examples/4.4 However, I have never used those for my tables, so I don't know how to use them.

Hello, i am newbie in node-red, how to change color button if i clicked it?
@ruwindustries 3 ай бұрын
You can set the Background Property of the Button to {{msg.color}} and then inject "green" in msg.color after you clicked the button. The string has to be a html color name. htmlcolorcodes.com/color-names/. If you need more help, please join the discord sever. There I can also send you some example code.

You should probably search for Tutorials or Explanations on the internet about using GPIO Pins, as this is not my expertise. There should be enough content about that. Otherwise, you may find someone on the community discord server that can help you out.

The Path /data only works if you use node-red from a docker container. If you run Node Red locally, the part before /static is different. I just use msg.path, so I can specify the path from a function.

You can set the value to a different msg property such as msg.mqttValue using a change. If the button doesn’t know the property it will send it through.

Good tutorial. But so far there's only 1 problem on my side. In my csv contain string like value (like device name), while my MySQL database column was created with varchar (255) type. But every time when I tried to insert, in the debug will give error: "Error: Unknown column 'DDC_1' in 'field list'". *DDC_1 here is for the device name column in MySQL. Is there any way to upload string/varchar value via CSV? Thank you for attention.

Seems like your insert command is wrong as DDC_1 should be the value and not the column name

Great content, the problem with this approach is that with each message sent, the layout is reloaded, generating a loop in the indicator. Ideally, it would update without reloading all the content.
