The view uses mini-graph and use the following sensors:

• for detecting day/night, since graph is 24h using this day/night makes it easy to identify approximated time of day
• shelly sensors for voltage and power
• energy meter sensors
• template sensor to calculate pricing

Pricing sensor calculation

# Information: https://forum.cpha.pt/t/contabilizar-os-custos-com-energia-electrica/3151
# Explicando os valores:
# 0.1008€/kWh é o custo da energia em vazio
# 0.1875€/kWh é o custo da energia fora de vazio
# 0.1456€/kWh é o custo da energia no tarifário normal
# 0.2292€/dia é o custo de 3.45kVA de potencia contratada
# 3.02€ é a soma das taxas e taxinhas (contribuições audiovisuais e afins)
# 1.23 para obter o valor da fatura com IVA a 23%

Shelly sensors

I use Shelly EM to monitor the power usage of the entire home, can be replaced by something similar.
