Power profiling my entire house with the Firefox Profiler

After showing last year how built-in power profiling features in Firefox can show very precisely how much power is used by code running in the browser, I will now show how I repurposed this tool to understand how power is used in my house.

I will explain how I installed various power meters in my house, how the data is collected, stored locally, then visualized. I will share how much 'just worked' and how much I had to adapt in the Firefox Profiler to make the visualization suit my needs, and finally show examples of interesting profiles revealing unexpected power use patterns.
