Hello, Specifics nodes need user/pwd informations like MQTT broker for example. If I want to persist informations after nodered restart, I need to put them in flows_cred.json. It works. If I only fill these informations directly in the flow, I will loose these values after nodered restart. Is t…

Hi Colin, Just to give you some precisions. I don't really have problems to store MQTT credentials. I can store them in flows_cred.json and after restarting nodered my credentials exist. I just try to find another way to persist my credentials whithout using flows_cred.json. I will have several …
