Just got the update from them and this is what they said (direct quote):
- In 100V 60Hz, in the case of Neutral, the switch can be used. In the case of Non-Neutral, the compatibility of AUX will be worse a bit, and adjustment is needed according to the actual test.
- In 100V 50Hz, at present, the dimming does not work normally, the AUX switch can’t be recognized. This requires additional development to target 50Hz.
- It is necessary to re-do safety / RF certification for Japan market.
- The installation method of the switch box also needs to be re-evaluated for Japan market.
