Homeassistant - Fujitsu airstage - full control with external wireless temperaturesensor

Third party integrations
1

As i can’ use no more accumulation I switched to use heat pumps. Finally I choose ‘Fujitsu’ which works, but there are some items on it I don’t like at all.
Everybody proposes me to use HomeAssistant, but asking for help how to, it seems I live on an Island
I found some info about Fujitsu Airstage from @danielkaldheim, but I can find nowhere a real nice answer on my problems below
Can someone help me please .

AS IS
fujitsu Airstage
3 intrnal units AGEG 09 KVCA
1 WiFi-dongle for each unit UTY-TFSXJ3

Contra:

  • temperature sensor is placed inside unit. This means always wrong measurment
  • Units are placed against exterior walls, meaning that measured temperature differs from real roomtemperature
  • Each 5 minutes, all units run for about 1 min to measure ‘real’ temperature. This generates a cold airstream
  • If too cold, to warm the external Unit starts and the internal unit starts.
  • The delta to start the units is too small, only 0.3°C
  • Only 4 different timesettings

Whish:

  • central placed wireless temperature sensors
  • Greater delta before units starts
  • Full control over ection units by the external sensors
  • NO temperature-test every 5 minutes, no test at all
  • Full control via homeassistant

Is this possible ?
What do I need as components ?
How setup homeassistant ?

Get your HomeAssistant working, and your temperature sensors integrated, and then you should be able to automate them working together.

You cant change how these aircons work. Temp sensor which is inside the unit is attached near the evaporator. And according to its temp, aircon has his own logic how to react. What you can do is:

  • adjust setpoint temp to the aircon lower (or higher) according to your real room mesurements by external temp
  • turn on/off the aircon when your target temp is reached.
