In the beginning, in my cursory searches for visualizing MQTT data from IoT devices, I ran across Node-Red and the Node-Red dashboards. It led me to using the v1 dashboard. I’ve built about a dozen flows using it and frankly it has worked flawlessly. I could have asked for a few bells and whistle…

To clarify what you are seeing, if you restart node red without sending data to the chart, is the cpu usage ok?

[image] Inq: Deploying is taking more than a minute and looking at my 8GB Raspberry Pi 4 server, I see the CPU is constantly running 25 to 30% even when I’m not deploying. A new release of Dashboard 2 is not going to fix this. I suspect you may have a runaway loop. Looking at the flow diagr…

[image] jbudd: A new release of Dashboard 2 is not going to fix this. It may do, depending on what @Inq 's flow did when the problem appeared. The bug in the existing dashboard is that if new data are added in Replace mode, the old data are not deleted, so if new data are added multiple times…

[image] jbudd: Grafana has this, I've not really explored it since like you I use MySQL rather than Influxdb. Grafana has built in support for MySQL.

[image] Steve-Mcl: In the meantime, it makes sense to reduce the amount of points a chart can physically occupy in pixels (e.g. if your screen is 1080 pixels across and you are displaying a chart that covers half of the screen then it makes little sense to show any more than 540 pixels. Altho…

[image] jbudd: I suspect you may have a runaway loop. Looking at the flow diagram in your other post (I didn't download it since your issue seemed to be resolved), I see there is indeed a feedback loop. Good eye and memory. @Colin made a suggestion to use Node-Red nodes to replace my kluge …

Before I add the FlowFuse module, I should summarize what I have in case someone sees something up front. I should note, all this works just fine using the V1 dashboard while showing no discernable lag after the initial loads. I should first describe my computer architecture. The server is a head…

Best to wait for the next release with various bug fixes in this area before running your tests.

When updates come out, does the Node-RED editor automatically update or prompt me or does one have to know that an update is available and update? I’ve installed FlowFuse already and I started a little simpler a single text box and gauge from an MQTT node. CPU utilization is fine so far, but the …

[image] Inq: When updates come out, does the Node-RED editor automatically update or prompt me There will be a notification in the bottom right of the node red editor [image] Or you can check any time in Manage Palette. Also there will be an announcement on the forum. How is the text widg…

High Dashboard v2 CPU Utilization

This is a known bug and will probably be fixed for the next release (no idea when that will be!)

I think you only get a notification of available updates if your settings.js file has a telemetry section with enabled: true and updateNotification: true
