Keep in mind if the SoC in there were only using 2 watts, it is radiating that heat from a surface probably smaller than the end of your thumb. For those old enough to remember 4 watt incandescent night light bulbs, you would know those (which had a much larger surface area) could still burn your fingers.
Took my outdoor base down found the hottest spot on the bottom temperature is 120 degrees.
I found the hottest spot on my modem and the temperature was 107 degrees
A wyze smart bulb is 150 degrees on cool white
a 60 Watt incandescent bulb Is running at 205 °F
Experiencing similar issue with heat on the bottom of the base station sitting inside the house with AC. While the base has vents on the bottom it sits flush to surface on all four sides no allowing for air to move. I added two strips of rubber with double sided tape on two sides of the base station (may have to add a little more height), I’ll let you all know if it helps with heat dissipation.
Update, it’s been 12 days since I added the strips. Slightly cooler but Still pretty hot on the surface where it sits and on the bottom of the base station. going to raise it some more to see if that helps.
great point, it’s gone from 118.3F (First reading) degrees down to 115.5F (today’s reading) . It’s been a hot month here in Southern California and we keep the house at 75 degrees (thanks to our Solar System), the base station is is sitting in direct shot of the ceiling register which is why i was expecting lower temps after created the gap on the bottom of the base to allow for some airflow.
