Fibaro heat controller attribute missing

I can control my Fibaro heat controllers (FGT001) fine.

In my lovelace card I would like to show if the attribute ‘heatRequired’ is true or false. However if I look in Development tools I don’t see this attribute mentioned when I look at the device.
If I look in the fibaro API this attribute can be checked.

What seem to work is if in the Developer tools I put heatRequired in the row where I can determine the attribute that determines the state. Then if I push the button “Define State” it seems to work.
However I’m affraid that after a reboot of HA the setting will be back to heat in stead of heatRequired.

No this doesn’t work. Is there any other way to get this attribute into HA?

Or is there a way to read ALL attributes from a Fibaro device?

Bumping the thread to see if anyone has a clue.

Sorry, I can’t help but would be interested in a solution…
