Sonoff POW vs POW2

[Dolby]

I'm selling two - but how do I know (without connecting) if POW or POW2 ?

I can't recall :/

Usually, I'd assume they'd write it on the cover but doesn't seem the case here as often just states POW?

if you pop the main cover off there might be a sticker on the relay inside, but you should also be able to tell from the chip

POW (HLW8012)
POW R2 (CSE7766 (alike))

It says Rev 2 right on the cover as per the picture.

If it doesn’t then it’s V1.
