Lots of methods to build a string, but, staying with the "Change Node" to build a string with text added to the msg.payload, use the Jasonata code method: Here is the JSON for above: =========== [{"id":"e9ea804.bae69","type":"change","z":"a45b533d.45c3b8","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"msg.payload & \"added text\"","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":410,"y":760,"wires":[["c65e9a7.5717768"]]}] |

¿ªÔÆÌåÓýUse a function nodemsg.payload = ¡°ZZGT¡± + msg.payload + ¡°;¡±; return msg; The above starting at msg.payload thru the ¡°;¡±; is all on line 1 and return msg; is on line 2 If the number from prior node is 56 you will have output ZZGT56;; Dave wo2x Sent from my waxed string and tin cans.?

Here is an example of a flow, using the "gate" node, triggered on TX>closed, and RX>open. ?Also, I have circled where you can get help on any node you select on the editor. ?Also, below is the JSON code for the example gate flow.

Re: NodeRed on Windows 10
Alan:
Yea....I was just playing with it, but it isn't worth all this.....runs fine on my Pi's. ha ha. I do have a quick question, if that's ok..... I'm trying to insert the output of one node (which outputs a number) into the middle of another string. I tried using a change node, and SET the msg.payload as xxxOUTPUTOFTHEPRIORNODExxx I've tried putting {{msg.payload}}, {msg.payload}, (msg.payload) and some other attempts to insert it, but none work.....I just don't know what syntax to use. The ZZGT is the command to change the AGC on the rig, and the trailing ; is the command end.? The prior node outputs a number. I'm trying to use the drop-down list to change AGC, and it outputs that number fine (using debug) but I don't know how to name it in the change node. Charlie |
