When they certify for North America, Xiaomi tends to use ETL which is completely fine. That’s a recognized certification organization in the US and Canada. UL and CSA are just different organizations to do the same thing in their respective countries. There’s also CUL which is UL certification for the United States and Canada. CE On the other hand is a self certification and means absolutely nothing as far as I’m concerned.
CQC or China Quality Certification, which is what’s on this relay that is intended only for the Chinese 50 Hz market 
, is voluntary, not compulsory, and again like CE really means nothing.
This is from the Aqara Hub box (Although it’s only the box that has that logo on it not the actual device 
). So yeah, there are some discrepancies there they need to work on!
