Hi all,

has anyone experienced persistent or 'ghost' wiring before??

Yesterday I spent way too long debugging a flow, I modified the flow due to a plugin being updated which altered the data it was sending which caused my flow to behave very erratically.

I deleted a wire, added some filtering etc but it still persisted with the erratic actions, although not visible on-screen it was acting as if the original link was still there.

After some hours i gave up and re-started the Node-Red app in my Home Assistant setup.

The restart gave an instant cure and all was well again.

Has anyone else seen behaviour where the flows actions do not match the screen layout??

Hi,

Can you share any more specific details here?

- What version of Node-RED (not the HA plugin, but NR itself)
- What type of nodes was the deleted wire connected to? In particular, the source node.
