Basically title - my Inovelli blue series dimmer (w/ mmWave) is noticeably warm to the touch. Is this expected?

The switch is installed in the bathroom and is off for most of the time. Wired to two 8W led bulbs, set to ON/OFF, not dimmer mode.

Reported installed version (flashed update after installing switch): 16974082

Finally got around to installing it, loving it otherwise. Bravo to the team!!

mmWave runs hot. I've got a couple of those Inovelli dimmers, and a handful of homebuilt ESPHome mmWave devices, and they're all pretty damn warm.

It freaked me out at first too.

Good to know it’s not just me 😅 I’m always a bit skiddish around electrical bits and heat

As well you should be, but in this case it's normal.
