Can you give an example ?
This flow doesn't work:
[{"id":"19d4447a.e78fcc","type":"tab","label":"Castv2","disabled":false,"info":""},{"id":"4ea4de1e.f255d","type":"castv2-sender","z":"19d4447a.e78fcc","name":"Smart Display","host":"192.168.1.113","x":540,"y":200,"wires":[["4200efb7.dfd73"]]},{"id":"4200efb7.dfd73","type":"debug","z":"19d4447a.e78fcc","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":720,"y":200,"wires":[]},{"id":"bcb22075.677ec","type":"inject","z":"19d4447a.e78fcc","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":200,"wires":[["c86dad8.105995"]]},{"id":"c86dad8.105995","type":"change","z":"19d4447a.e78fcc","name":"","rules":[{"t":"set","p":"payload.media.url","pt":"msg","to":"rtsp://admin:1234@192.168.1.103:554/cam/realmonitor?channel=1&subtype=0","tot":"str"},{"t":"set","p":"payload.type","pt":"msg","to":"MEDIA","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":340,"y":200,"wires":[["4ea4de1e.f255d"]]}]
I believe this is in the "change" I don't give the info it needs.
Thank you
