Sometimes wiring becomes a mess because the wires follow the shortest path. Can you somehow change the route of the wires?

The "shape" of the individual bezier curves is defined inside the editor's javascript logic -- so you cannot directly change the route that each wire takes. However, you can keep your flows more tidy using one or more of these techniques: Use the link out - link in pair of nodes to route wires f…

Link nodes are what I use extensively to keep my flows super tidy. [image] Sometimes anyway :slight_smile: [image]

I have simple rule set: If there is wire, crossed by more than 1 wires, then it is "work in progress". If there is wire, crossed by 1 wire, then it is luck of clear thinking (equals to being lazy). If there is wire between nodes but outer ends are not connected to anything and all systems are up …

Oh, and I should have added a 4th option: use MQTT and the msg.topic to route the output of one part of your flow to the input of another part Julian's heating system reminded me of this -- and since the MQTT broker has the ability to persist the last published msg, it is an excellent way to have…

[image] shrickus: it is an excellent way to have your flows reconnect at startup, and pick up the last msg in order to re-initialize anything that relies on stored state Agreed, working fine for a Node-RED restart. Just be aware that to also "survive" a reboot, the MQTT broker has to be runn…

Aha, ok. So means the broker keeps the (retained) data persistent in some way. I did not know, thank you!

As usual it depends. Again you have to configure Mqtt to persist data to storage rather than memory if you want it to survive a complete power cycle reboot.

[image] krambriw: I have understood, this is not the default setting for mosquitto? On Raspbian and Ubuntu (at least) it is the default, I believe. Looking at /etc/mosquitto/mosquitto.conf I see persistence true persistence_location /var/lib/mosquitto/
