Hi everyone,

i need to create a simple boolean logic flow, but my flow like no responsive can give me some idea thanks.

```auto
[{"id":"9759bf8f80f65b09","type":"tab","label":"Flow 1","disabled":false,"info":"","env":[]},{"id":"7ecde2aa3507439e","type":"inject","z":"9759bf8f80f65b09","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ts","payload":"1","payloadType":"num","x":110,"y":100,"wires":[["93431e6e72be9d77"]]},{"id":"fdb50b022521b891","type":"inject","z":"9759bf8f80f65b09","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ts","payload":"0","payloadType":"num","x":110,"y":140,"wires":[["748b00670fb5b4e2"]]},{"id":"882ed86e8d0df912","type":"debug","z":"9759bf8f80f65b09","name":"debug 1","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":640,"y":120,"wires":[]},{"id":"93431e6e72be9d77","type":"change","z":"9759bf8f80f65b09","name":"","rules":[{"t":"set","p":"topic","pt":"msg","to":"ts1","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":270,"y":100,"wires":[["def664e791416e80"]]},{"id":"748b00670fb5b4e2","type":"change","z":"9759bf8f80f65b09","name":"","rules":[{"t":"set","p":"topic","pt":"msg","to":"ts2","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":270,"y":140,"wires":[["def664e791416e80"]]},{"id":"def664e791416e80","type":"switch","z":"9759bf8f80f65b09","name":"","property":"topic","propertyType":"msg","rules":[{"t":"true"},{"t":"false"}],"checkall":"true","repair":false,"outputs":2,"x":450,"y":120,"wires":[["882ed86e8d0df912"],["882ed86e8d0df912"]]}]

You either need to convert your payloads to booleans, or check in switch node if payload value is number 1 or 0.  
e.g.

```auto
[{"id":"def664e791416e80","type":"switch","z":"9759bf8f80f65b09","name":"","property":"payload","propertyType":"msg","rules":[{"t":"eq","v":"1","vt":"num"},{"t":"eq","v":"0","vt":"num"}],"checkall":"false","repair":false,"outputs":2,"x":450,"y":120,"wires":[["882ed86e8d0df912"],["4a53936d063cb9c7"]]},{"id":"7ecde2aa3507439e","type":"inject","z":"9759bf8f80f65b09","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ts","payload":"1","payloadType":"num","x":110,"y":100,"wires":[["def664e791416e80"]]},{"id":"fdb50b022521b891","type":"inject","z":"9759bf8f80f65b09","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ts","payload":"0","payloadType":"num","x":110,"y":140,"wires":[["def664e791416e80"]]},{"id":"882ed86e8d0df912","type":"debug","z":"9759bf8f80f65b09","name":"debug 1","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":640,"y":120,"wires":[]},{"id":"4a53936d063cb9c7","type":"debug","z":"9759bf8f80f65b09","name":"debug 0","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":620,"y":160,"wires":[]}]
