Make sure there is at least a short period of steady state running in the window. Heat output spikes after hot water cycles can skew results.

Calculate DHW Standby Heat Loss Coefficient
Ensure the selected window only shows natural DHW temperature decay (no heating cycles, no DHW use such as showering). Cylinder volume and environmental temperature are required to compute standby heat loss coefficient, which only works if DHW temperature is measured in °C and not % Charge.

The My Heatpump app can be used to explore the performance of a heatpump including, electricity consumption, heat output, COP and system temperatures.
Auto configure: This app can auto-configure connecting to emoncms feeds with the names shown on the right, alternatively feeds can be selected by clicking on the edit button.
Cumulative kWh feeds can be created from power feeds using the power_to_kwh input processor, which converts power data (measured in watts) into energy consumption data (measured in kWh).
Share publicly: Check the "public" check box if you want to share your dashboard publicly, and ensure that the associated feeds are also made public by adjusting their settings on the feeds page.
Start date: To modify the start date for cumulative total electricity consumption, heat output and SCOP, input a unix timestamp corresponding to your desired starting date and time.
