Octopus Energy
Power your home when energy is cheapest and greenest.
Octopus Energy for Homey brings your live half-hourly electricity and gas prices, your energy usage and cost, your tariff's standing charge and your account balance straight into Homey, so you always know exactly what your energy is doing right now.
Use it to run your dishwasher, EV charger or immersion heater when power is at its cheapest and greenest, with Flow cards that react to price drops, negative "plunge" pricing and the cheapest upcoming half-hours. This is an unofficial app and is not affiliated with, or endorsed by, Octopus Energy.
