Hi Lumanga,

it seems to me, that you have to use context variable. Please import the attached flow and inspect nodes.

```auto
[{"id":"174aad89f01f41e5","type":"ui_text","z":"ef1fc105685aed46","group":"e924fd1fd06cf83a","order":2,"width":0,"height":0,"name":"","label":"Button msg:","format":"{{msg.payload}}","layout":"row-spread","className":"","x":710,"y":360,"wires":[]},{"id":"e924fd1fd06cf83a","type":"ui_group","name":"Default","tab":"854bd9cd49df7ac1","order":1,"disp":true,"width":"6","collapse":false,"className":""},{"id":"854bd9cd49df7ac1","type":"ui_tab","name":"Home","icon":"dashboard","disabled":false,"hidden":false}]

```

I hope it helps.

Stepan

An alternative is to use a node-red-contrib-simple-gate node (which you have to install via Manage Palette).  
It can be set up so that an ON message from the switch opens the gate, allowing messages from the button to pass and OFF closes it, blocking the button messages.

Or use a join node and a switch node.  
e.g.

```auto
[{"id":"725512a1.b50eec","type":"ui_switch","z":"bf9e1e33.030598","name":"","label":"switch","tooltip":"","group":"2d4fe667.28f8ba","order":8,"width":0,"height":0,"passthru":true,"decouple":"false","topic":"switch","topicType":"str","style":"","onvalue":"true","onvalueType":"bool","onicon":"","oncolor":"","offvalue":"false","offvalueType":"bool","officon":"","offcolor":"","animate":false,"className":"","x":190,"y":2080,"wires":[["6dc8aa87.cc473c"]]},{"id":"6dc8aa87.cc473c","type":"join","z":"bf9e1e33.030598","name":"","mode":"custom","build":"object","property":"payload","propertyType":"msg","key":"topic","joiner":"\\n","joinerType":"str","accumulate":true,"timeout":"","count":"2","reduceRight":false,"reduceExp":"","reduceInit":"","reduceInitType":"","reduceFixup":"","x":320,"y":2120,"wires":[["9056566f.da35d8"]]},{"id":"8ce1886b.667c78","type":"ui_button","z":"bf9e1e33.030598","name":"","group":"2d4fe667.28f8ba","order":9,"width":0,"height":0,"passthru":false,"label":"button","tooltip":"","color":"","bgcolor":"","className":"","icon":"","payload":"the payload","payloadType":"str","topic":"button","topicType":"str","x":190,"y":2180,"wires":[["6dc8aa87.cc473c"]]},{"id":"9056566f.da35d8","type":"switch","z":"bf9e1e33.030598","name":"","property":"payload.switch","propertyType":"msg","rules":[{"t":"true"}],"checkall":"true","repair":false,"outputs":1,"x":460,"y":2120,"wires":[["c4eb9de8.b47e3"]]},{"id":"c4eb9de8.b47e3","type":"change","z":"bf9e1e33.030598","name":"","rules":[{"t":"move","p":"payload.button","pt":"msg","to":"payload","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":680,"y":2120,"wires":[["93e51fcb.ead128"]]},{"id":"93e51fcb.ead128","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":580,"y":1920,"wires":[]},{"id":"2d4fe667.28f8ba","type":"ui_group","name":"demo","tab":"1caa8458.b17814","order":1,"disp":true,"width":"12","collapse":false},{"id":"1caa8458.b17814","type":"ui_tab","name":"Demo","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

```

or use the switch to enable / diable the button  
e.g.

```auto
[{"id":"8ce1886b.667c78","type":"ui_button","z":"bf9e1e33.030598","name":"","group":"2d4fe667.28f8ba","order":9,"width":0,"height":0,"passthru":false,"label":"button","tooltip":"","color":"","bgcolor":"","className":"","icon":"","payload":"the payload","payloadType":"str","topic":"button","topicType":"str","x":160,"y":1980,"wires":[["93e51fcb.ead128"]]},{"id":"c4eb9de8.b47e3","type":"change","z":"bf9e1e33.030598","name":"","rules":[{"t":"move","p":"payload","pt":"msg","to":"enabled","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":370,"y":2020,"wires":[["8ce1886b.667c78"]]},{"id":"93e51fcb.ead128","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":580,"y":1920,"wires":[]},{"id":"725512a1.b50eec","type":"ui_switch","z":"bf9e1e33.030598","name":"","label":"switch","tooltip":"","group":"2d4fe667.28f8ba","order":8,"width":0,"height":0,"passthru":true,"decouple":"false","topic":"switch","topicType":"str","style":"","onvalue":"true","onvalueType":"bool","onicon":"","oncolor":"","offvalue":"false","offvalueType":"bool","officon":"","offcolor":"","animate":false,"className":"","x":160,"y":2020,"wires":[["c4eb9de8.b47e3"]]},{"id":"2d4fe667.28f8ba","type":"ui_group","name":"demo","tab":"1caa8458.b17814","order":1,"disp":true,"width":"12","collapse":false},{"id":"1caa8458.b17814","type":"ui_tab","name":"Demo","icon":"dashboard","order":1,"disabled":false,"hidden":false}]
