Yes, you need both the receiver and the thermostat. Whilst you can ignore the thermostat (and use any temps Ensor you like), it is quite accurate and so is useful as such.
My method is to have the Hive App in ‘manual mode’ (in fact the app has been deleted) and everything is controlled via HA. To ensure this works, I have an automation that does everything including ensuing the mode is correct when HA restarts.
The following might help you. Note I have truncated sensor.hive_heating_target_temp as it is a long and not central to this point. The entire package is here if you are interested, but I have tinkered with it since to include a schedule setting that reacts to my house ‘waking up’ with a ‘pre-heat’ to warm the house before ‘waking up’).
