Herewith I share my implementation for the Atlantic Aurea hybride heatpump. Feedback and suggestions are welcome!
Atlantic Aurea is a hybride heatpump that switches between traditional gas a and heatpump heating. It comes with the Plugwise Smile Opentherm module and a Plugwise Anna thermostat. (see Aurea Hybride add-on - Atlantic Therefore, it can be integrated in Home Assistant using the Plugwise integration.
Unfortunately, there is no direct way to set it to gas or heatpump operation. I experimented with some parameters to influence this. I use an automation that manipulates the Anna thermostat between certain limits to ‘force’ the heatpump mode instead of gas where possible. As long as the outside temperature is higher than 4.5 degrees, it keeps the heatpump running when there is a heat request.
The Anna thermostat is only used to controll the Atlantic aurea, and is in my case located near the gas heater. Instead I use zwave radiator thermostats, so the user can set the temperature there, but couls also be done using a seperate wall thermostat that sets the input helper.
I use multiple temperature sensors in the house and an input_number helper that can be set to enter the desired temperature per room. finally I calculate the difference between de desired temperature and the measured average temperature. This is called the temperature_request.

Stuff for the nerd
Code below is my package (see Packages - Home Assistant) that defines both helpers and the automation.
it defines these entities:
| entity | description |
|---|---|
| input_number.heatpump_setpoint | temperature that the controller wil set the Anna to in order to manipulate it |
| input_number.temperature_target | desired home temperature |
| sensor.temperature_avg | Average temperature for a room when multiple temperature sensors are used |
| sensor.temperature_req_generic | ultimate heat request from all rooms |
| sensor.temperature_req | calculated hear request (difference between measured and requested temperature) |
| sensor.heatpump_status | indicator if the heatpump is in heatpump or hybrid mode |
| sensor.delta_water_heat | actual amount of degrees the unit feeds into the house |
| sensor.delta_setpoint | difference between actual Anna setpoint and anna temperature |
| sensor.heating_capacity | Percesntage heating power used, for both gas or electric |
| sensor.heatpump_capacity | percentage power used for heatpump only (based on electricity usage measurement) |
| binary_sensor.heatpump_active | indicating if the heatpump is on |
Note: the capacity of the heatpump is measured using a power plug meter the heatpump is connected to. (in my case sensor.heatpump_electric_consumption_w)
Additionally, it requires the following sensors:
| sensor | description |
|---|---|
| input_boolean.heatpump_force | helper entity to enable or disabling the manipulation |
| sensor.smile_anna_outdoor_temperature | provded by Plugwise Anna thermostat |
| sensor.opentherm_modulation_level | provded through Plugwise Smile by you gas heater using OpenTherm |
| sensor.opentherm_water_temperature | provded through Plugwise Smile by you gas heater using OpenTherm |
| sensor.opentherm_intended_boiler_temperature | provded by Plugwise Smile |
| sensor.opentherm_return_temperature | provded through Plugwise Smile by you gas heater using OpenTherm |
| binary_sensor.opentherm_tap_water | provded through Plugwise Smile by you gas heater using OpenTherm |
| climate.anna | provded by Plugwise Anna thermostat |
