No, you don't need to do anything if you install a heat pump.
The FlexiO algorithm is designed to automatically take your consumption into account and includes your consumption history. As soon as the heat pump starts and electricity consumption increases, FlexiO will automatically take this into account and recognises the heatpump consumption pattern.
FlexiO learns not only the size of the consumption, but also the new usage pattern.
Note: FlexiO cannot control the heat pump itself - only the battery, EV charger and inverter.
