Plug Plus S high temperature

Hello,

does someone know what the normal or average operating temperature of the Shelly Plus Plug S is? I noticed is is 10°C hotter than the Shelly Plug S.

With a room temperature of 24°C the Plus Plug S is 44°C where the Plug S is 33°C.

I have seen it going up to 48 so far. I think this is quiet hot. But not sure what is normal and acceptable for the new Plus Plug S.

Any comments?
