Good day everyone! I almost finished an app that will run on multiple machines (powered by Raspberry Pi's). None of these machines have a fixed IP and all of them will send some data to a server at regular intervals of time. Is there a way to update the flows in this case? I was thinking something…

Welcome to the forum @Cristian You could do a regular git pull on the server and then restart node red if it pulls anything

Will that update the flows or just node red? The way I read it if he changes flows on one machine then update all machines to the new flow.

I meant to pull the flows from git. I am assuming they are in a git repo on GitHub or wherever.

Thank you for your answer. NR machine will send a request to server to check if there are any updates available. If a new version of SW is available then the server will send the updated json flows. Now how can I fully deploy the new version of SW automatically without any human intervetion?

Thank you for your answer. After pulling just overwriting the old flow will do it?

Have you considered using a dynamic dns service (like duckdns) and to use machine names instead of ip addresses? This could save you the trouble of updating the flows when the IP Addresses of the machines change.
