Domoticz, solarpanels and inverters

Sunday 13 September 2020

Back in August 2018 we got 20 solarpanels installed on our carport. The vendor (SolarEdge) of the inverter provides an app and a monitoring website where we can see how the installation is performing.

We were already using Domoticz to monitor our power and gas usage. Domoticz comes with an option to extract data from the SolarEdge monitoring platform and present it. All the energy data available in one dashboard; a great way to see what is going on.

Great right? Well, yeah. It’s working perfectly, so no complaints. But there’s this nagging thingie… To get to the performance data of our panels, we are required to use the monitoring platform of the vendor. And it’s also clear that SolarEdge receives more information from the inverter than they share back to us via their API.

So, why not collect this data directly from the inverter?

Photo tagging and resizing

Sunday 9 August 2020

I ended my photo cleanup post with the statement that I should review how I resize images and handle the Exif tags in them.

That process took over 30 hours to resize the (5.000+) photos on the site and still resulted in some issues. Over the last weeks, I switched to another toolset to do the resizing. It now takes less than 1 hour to resize the images and so far, I have not found any issues with the results.

Fun with Jekyll plugins

Sunday 28 June 2020

Earlier this year, I started to rebuild my website and decided to rebuild it with a static site generator: Jekyll. While building the site, I had some design principles in mind:

  • The HTML pages should contain as little clutter as possible.
  • The site should look good on smartphones, tablets and computers.
  • Try to limit the amount of processing that needs to be done by the browser.

This requires processing of the photos and GPS tracks while generating the static HTML files. To do that, there are lots of plugins out there that can help. I found quite some plugins that can-do parts of the trick, but in the end, I still ended up with issues. But hey, I am an IT-guy; I can build a plugin myself, right?

Photo cleanup

Sunday 31 May 2020

Over time, I used different methods to add GPS information to my photos. After the release of my static website, I noticed that lots of photos showed wrong or incomplete data. Time to investigate.

I started this website back in 2009 and based on WordPress. By using WordPress, I hoped that I could focus on the content and didn’t have to spend a lot of time on the technology. Boy, was I wrong…. Time for a major overhaul.
