One of the students in my IoT Computer Club (here in the UK) is working on a personal project to design and build a solar-powered weather station (that will be located in one of the school's gardens) to monitor and report air temperature, humidity and pressure. Here are the Objectives and list of i…

Thanks for the feedback Paul, I'll have to have a serious look at Grafana and see how I can incorporate it into the Club's future plans and projects.

OK Paul you have got me 'hooked' - that looks brilliant. I really like the way you can zoom into a certain timeframe and expand the plot. How long did it take you to create it? Thanks for sharing your work - I really do appreciate it.

[image] dynamicdave: How long did it take you to create it? I'm not very familiar with databases, queries etc, so it was initially a steep learning curve, with lots of googling over many nights. Once I got my head around the concept, it all seemed to fall into place pretty quickly. The most …

[image] Paul-Reed: every 5 seconds, so that's over 17,000 data points per day Yes, I believe that Grafana does the "right" thing and automatically downsamples the displayed points according to the chart size and resolution. While Dave (the other dynamic one :slight_smile:) has done what he c…

I had problems between Grafana and Influxdb because of formatting issues whilst storing data to Influxdb. I was put on the right track by changing the way the data was stored and then Grafana 'just worked' and is very easy to add graphs, charts, dials, tables etc. Here is a snapshot of mine which I…

Hi Martin @Cathprotech Woo - your dashboard is impressive. I must seriously consider introducing Influxdb and Grafana into my IoT classes. Thanks for sharing your work.

Thanks David. My biggest problem was writing the data to Influxdb in a format that could be read by Grafana. Once that was done, honestly Grafana is so easy. What I have done is very simple yet the results are impressive. Imagine what I could do if I actually knew what I was doing. My Influxdb p…

@dynamicdave do your BME280's read an accurate temperature ? I have a couple, but they are all off by 5 degrees Celsius (it appears to be exact 5) I have no idea how this is possible.

Another graphing possibility is InfluxDB's Chronograf. While not as advanced as Grafana it does integrate easily with the InfluxDB database and does not have a steep learning curve.
