This is my first post and second day using Node-RED.
Yesterday, after a few hours I had a dashboard with a couple of guages displaying the data of a couple of Arduino MODBUS servers. The Modbus client is an S7 PLC watering the plants in my polytunnel. This has been trouble free for almost 4 years.
Last night, I even managed to configure an email node to forward a water tank level to a couple of my email addresses. After a few dozen exciting emails '', my water tank level as %, I was getting a message 'failed to deploy, device full, write' or similar. I tried deleting all the nodes but no more fun was to be had. I tried to reboot my Raspberry Pi 3 B+ but it would hang at the point just before the desktop would normally appear. Several hours on Google and a few things to try later and I decided to reinstall the latest NOOBS when I got home this evening. after about 4 hours I had my Pi close to where it was last night, albeit with the very latest NOOBS, Arduino IDE, etc.
I used the script on the Node-RED website to remove the pre-installed Node-Red and update to the latest. I was back to enjoying Node-RED. I tried to recreate my simple dashboard but after only 10 minutes or so I could no longer load my workspace or dashboard in the browser. It behaves exactly like when there is no internet connection, 'page cannot be reached'. I have access to any web page I try but cannot get the Node-RED workspace to load. The Node-RED console is running and I see the IP of the Modbus server in the text. I see ....status1 Failure... In the scrolling screen. I have no firewall or proxy settings that were changed.
My first question is 'why did it stop working after only 10 minutes?
My second question is 'how do I clear what is happening in the console so that I can try again?
I am totally inspired by all the weird and wonderful things people around the world are achieving. Unfortunately, I have no peers who may be able to help. None of my friends or colleagues have heard about Node-RED until today.
I have not found a similar issue on Google so I thought I'd introduce myself to the forum.
