This is an article I wrote for Verv during their Seedrs fundraising campaign in March 2024. Link to article.

This January, we finished the installation of the first Verv Smart Isolator with our partner Nido, a Spanish heat pump provider. A Verv Smart Isolator was attached to an air-to-water heat pump and in less than a week, we provided actionable insights for the customer.

One of the tools that helps us understand the energy usage patterns is the energy-utilization heatmap. The heatmap visualizes the hourly energy consumption over different days (vertical axis) and times of day (horizontal axis). The intensity of colour - marked in the legend - represents the energy expenditure during each hour, with darker colours indicating higher usage.

Like to parkrun? I certainly do! This project helps you to visualize where you’ve been running, and where you could go next. Simply run the app locally with Python, and enter an athlete ID (e.g. your own one).

I’ve used Plotly Dash to render the parkrun participation on a map for a given athlete. The map initially starts out centred on your home parkrun course - the one you’ve visited most - just zoom out if you’ve gone farther afield.
