Something is using up all the memory. Stop node red then restart it using node-red --safe
and it will start the editor without starting the flows. You said that it was since you installed the broadlink node (whatever that is). Have you configured and wired up a broadlink node or is it installed but not in use? If it is not in use then uninstall it again and see if that fixes it (the flows will start when you deploy). If it is wired up then disconnect it and see if that fixes it. It may not be the node that is at fault but something you are doing with it.
ok, did knew the safe-mode, i can access now,,, deinstalled al the broadlink stuf but the problem still exists...
Looks like i cant execute domoticz and node-red on the same rpi 4b 8mb anymore,...
When i deinstalled broadlink from the palette,is it then also removed from OS ?
When you remove a node from node-red do you also remove it from the operation system, other words, totally deleted and no options to interfere..
@update: i think i found the disturbing issue, i think it has to do with mqtt.
I disabled mqtt in domoticz en now my node-red responces well!
I can see that mqtt has new options in node-red node. Maybe i have to change some of these to get this problem solved.
Not an mqtt expert, perhaps somebody has optimized it with the same kind of setup like me:
Most likely you have an mqtt feedback loop setup... ie you send something from Node-RED to Domoticz which then updates something and sends it back to Node-RED which then feeds it back again... eg a switch ? maybe ?
The other possibility is that you may have set up two clients with the same clientID (normally it's easier to leave them blank to be assigned randomly) - if they are the same then they will take turns knocking each other off the system thus wasting time and resources.
Yep, i also think it must be something like that!
i am gonna cleanup my config and disable the mqtt out of my NR to check!.
Problem is that i think you cant config which domoticz devices are send by domoticz to mqtt, it looks like all or nothing...
