Hi ! Sometimes, i have some bug with the wire of some nodes. I use the latest version NR 2.2 The output wire of the node multiply the message (here 3 wires) I don't know how it's happen (merging, deploy, copy paste ....) ? If you have somes ideas... Thanks in advance for your help ! PS : Debugger can help to see what happen :wink: [ { "id": "dbb85b569c600d88", "type": "exec", "z": "514053c7b34aa0bc", "command": "echo $HOME", "addpay": "", "append": "", "useSpawn": "false", "timer": "", "winHide": false, "oldrc": false, "name": "", "x": 920, "y": 1360, "wires": [ [ "aba38453d06cbbe4" ], [], [] ] }, { "id": "41215627dd511af0", "type": "inject", "z": "514053c7b34aa0bc", "name": "", "props": [ { "p": "payload" }, { "p": "topic", "vt": "str" } ], "repeat": "", "crontab": "", "once": false, "onceDelay": 0.1, "topic": "", "payload": "", "payloadType": "date", "x": 740, "y": 1360, "wires": [ [ "dbb85b569c600d88" ] ] }, { "id": "aba38453d06cbbe4", "type": "debug", "z": "514053c7b34aa0bc", "name": "", "active": true, "tosidebar": true, "console": false, "tostatus": false, "complete": "false", "statusVal": "", "statusType": "auto", "x": 1130, "y": 1340, "wires": [] }, { "id": "8b57a776ae5311e1", "type": "exec", "z": "514053c7b34aa0bc", "command": "echo $HOME", "addpay": "", "append": "", "useSpawn": "false", "timer": "", "winHide": false, "oldrc": false, "name": "", "x": 920, "y": 1260, "wires": [ [ "0ab9500540f25909", "0ab9500540f25909", "0ab9500540f25909" ], [], [] ] }, { "id": "ca560554a48854a3", "type": "inject", "z": "514053c7b34aa0bc", "name": "", "props": [], "repeat": "", "crontab": "", "once": false, "onceDelay": 0.1, "topic": "", "x": 750, "y": 1260, "wires": [ [ "8b57a776ae5311e1" ] ] }, { "id": "0ab9500540f25909", "type": "debug", "z": "514053c7b34aa0bc", "name": "", "active": true, "tosidebar": true, "console": false, "tostatus": true, "complete": "payload", "targetType": "msg", "statusVal": "payload", "statusType": "auto", "x": 1185, "y": 1240, "wires": [], "l": false } ]

[image] Possible bug ( UI dashboard switch node or function switch Node) General @Colin I posted on the Github issue page a case that it happens to me and that I could replicate every time .. and thats is when i use the undo (Ctrl-Z). I posted an animated gif showing how to test. Node-RED version: v2.2.0 Node.js version: v14.18.2 Windows 10 tested both Firefox and Chrome. Looks like imilar issue as explained here.

The workaround to fix it when this happens is to delete the wire (which does not actually seem to do anything), then Deploy which will leave you with just the one wire.

Ok thanks for your reply. Hope it will be fixed quickly Thanks for the team Regards.

[image] bigman: Hope it will be fixed quickly A PR has been published and will be included in a patch release (hopefully) within the coming days. For reference: the issue has been raised here: Duplicate wires between nodes with 2.2.0 · Issue #3433 · node-red/node-red · GitHub

About a month ago I added a new (to me and NIB) LED strip controller and a Pico button for local control. It's had some goofy behavior and I just figured it was the controller but today I went looking to see why the sequence (flow, if you must) was producing double messages and found it was this issue. Now I wonder if I have it lurking somewhere else that I don't know about yet and I'd like some script, or such, to find if I do. Has anybody done this scan already? @Steve-Mcl ?

This issue has been handled and mitigated if you upgrade to version. 2.2.2. You won't need to do anything other than update and restart. You can, if you wish, do a browser refresh, full deploy to actually remove the duplicate wires in the flow file permanently (but it's not 100% necessary since they are removed in the runtime at load & won't cause the double message issue).

[image] Steve-Mcl: version. 2.2.2 I've been on 2.2.2 since a few days after it was released and the sequence was deployed many times including some "fulls".
