I’ve started toying around with home automation, managing to add a few Z-wave sensors to OpenHab. Recently I’ve managed to switch RF-plugs on and off with a 433-MHz emitter/receiver set with the Raspberry Pi.
I’ll be in Beijing for a week in Spring.
Shopping online for sensors one immediately realizes that a lot of them come or seem to be made in China.
The general question
I am strongly tempted to use the opportunity and try to buy in situ all the sensors etc I would otherwise not dare order per AliExpress etc. Is there anything obvious I may be overlooking which speaks against this? The potential lack of warranty is not a big issue.
The specific question
Has any of you been recently in Beijing and would have some pointers as to where one should go (beside what one finds immediately in Google, e.g. Zhongguancun Hailong Electronics Supermarket)?
Thanks in advance and happy OpenHabbing!
