#hash of theurlwhile scrolling through the page. I was inspired by How To Update URL Hash On Scroll (With Table Of Contents) on Stackoverflow and by ChatGPT suggesting the Intersection Observer API api. -
Calculating Degree Days in Home Assistant
Calculating Degree Days (or Graaddag in Dutch) allows you to benchmark gas consumption in relation to temperature. The formula is quite simple, it uses as reference temperature 18°C minus the average temperature of the day, minimized on 0°C. The concept is based on the idea that the amount of energy needed to maintain a comfortable indoor temperature increases as the difference between the indoor temperature and the outdoor temperature increases. By tracking the degree days, it is possible to estimate how much energy is needed to heat or cool a building and compare it to the actual energy usage.
This configuration is using the Home Assistant platform to define two sensors:degree_day_dailyandgas_m3_per_degree_day. Thedegree_day_dailysensor calculates the difference between a regularized temperature (18.0°C in this case) and the average temperature reported by thesensor.garden_garden_temperature_noordkant_temperaturesensor over the past 24 hours. Thegas_m3_per_degree_daysensor calculates the gas usage (as reported by thesensor.gas_delivery_dailysensor) per degree day, which is defined as the difference between the regularized temperature and the average temperature. -
Flanders/Belgium's Capacity Tariffs in Home Assistant
Flanders will reform the nettariffs for electricity transport, shifting a larger cost to peak usage. They do this by measuring your average consumption per 15m and the maximum quarter of the month counts as your tariff. Currently information and dashboards from Fluvius are cumbersome to use (CSV export and then leveraging Excel to spot the highest quarter).
