[Pranav]

I have a button which sends 0 and 1 for off and on,

and i want another button to change its property on label or off label .

but it is not working, also there is problem in button set property which shows on label twice.

How can i solve this one?

I’ve changed the category of this to “need help”, as “issues and errors” is best used for Blynk related issues rather than 3rd party issues.

The problem you’re experiencing isn’t a an error, it’s a way of preventing infinite feedback loops from being created.
To achieve what you want, you need to use the Bridge widget, as described in this post:

MQTT data via Node-Red To Blynk to controll NodeMCU connected hardware

Yes it can, see this example: But, that doesn’t answer your question. If I understand your problem correctly (and I’ve tried your code and what I think you used as the Node-Red flow and re-created the issue) then you need to use the Bridge node. [image] Here’s the Bridge Node setup, with the same auth code as you used in your connection: [image] Serial Monitor output: TEST:512 CO2 Data:336 TEST:336 CO2 Data:580 TEST:580 The display widget in the app attached to V6 also gets updated…

Then @PeteKnight What is the use of setproperty button? any specific applications?

[PeteKnight]

The documentation is fairly self explanatory…

Blynk set property node.

This node will write the value in payload to specified property at the specified pin number.

“Pin mode” selects whether the pin number is fixed or dynamic
Fixed, select the pin number in the interface
Dynamic, the pin number is passed through msg.pin property

Use the node property by select on menu or override using msg.prop

To set multiple properties use this syntax:
msg.label to set the Label property
msg.color to set the color property
msg.min to set the Min property
msg.max to set the Max property
msg.onlabel to set the onLabel property (only Button and Styled Button widget)
msg.offlabel to set the offLabel property (only Button and Styled Button widget)
msg.onColor to set the onColor property (only Styled Button widget)
msg.offColor to set the offColor property (only Styled Button widget)
msg.onBackColor to set the onBackColor property (only Styled Button widget)
msg.offBackColor to set the offBackColor property (only Styled Button widget)
msg.labels to set the Labels property (only Menu widget)
msg.isonplay to set the isOnPlay property (only Media Player widget)
msg.url to set the url property (only Video Straming widget)
msg.step to set the step property (only Step Control widget)
msg.maximumFractionDigits to set the maximumFractionDigits property (only Slider widget)
msg.opacity to set opacity in range 0-100% (only Image Gallery widget)
msg.scale to set scale in range 0-100% (only Image Gallery widget)
msg.rotation to set rotation in range 0-360 degree (only Image Gallery widget)
msg.url and msg.imgid to load url to specific image index (only Image Gallery widget)
msg.urls (array of string) to load images on gallery widget (only Image Gallery widget)
