I have measured today surface temperature of my PWR-Line AP and I got 44,5°C (room temp ~ 22°C)
That seems to be quite high to me.
Are you considering some power optimizations for next revision of the HW?
This is worrying, I was thinking of installing these in an old house made of wood that can get very hot in the summer, but with these temperatures it does not seem safe. Has there been some firmware updates that has addressed this issue? Does the PWR-LINE PRO reach similar temps?
