I too have been using Cosy. I was originally skeptical that it would make sense for heating, but it’s been working out surprisingly well. See my analysis before I switched plus my experiences with it here: > [@Projections of running Heat Pump on Cosy Octopus tariff \[UK\]](https://community.openenergymonitor.org/t/projections-of-running-heat-pump-on-cosy-octopus-tariff-uk/24250): > > I’ve been looking into which electricity tariff to switch to after my fixed one runs out next month, and so I’ve been doing detailed simulations using historical data from emoncms in various scenarios. I thought it might be useful to share my findings (with caveats). Property: a 1950s bungalow with mediocre insulation, 11 kW heat pump, 5 kWp solar panels on east facing roof and 8.65 kWh of (usable) battery storage. No electric car. (I’ve not shown the effect of PV generation here) Methodology:… --- _[View the full topic](https://community.openenergymonitor.org/t/weather-compensation-ashp-duty-cycle/24793)._
