For Mijia Light Sensor, Smart Home with Light detection, Smart Link, Waterproof Function Mijia APP Support

This is the Xiaomi Light Sensor, but you don't need to use their dedicated app/hub. No idea if works with Amazon Echo's Zigbee hub, but managed to get into SmartThings with a bit of research. I'm no coder, but fortunately others are.Basically you need to be familiar with Groovy IDE, and search the SmartThings community for a post on a custom device handler for Xiaomi Light Sensor. It's very straightforward... copy code, create new handler in Groovy IDE, paste, save, publish locally. I added as generic z-wave device just to get it in SmartThings as a "thing", and then changed device type to the custom handler in groovy. You may uave to go to settings on SmartThings app, or on IDE, to push configuration file through, but that's it.Not plug and play.... but does work in ST. Adding new sensors after first one is a lot easier. Obviously this will be oudated when Samsung kill off IDE but by then the T-3000s will have taken over the planet.

I bought two of these. The first was damaged and would not go into pairing mode. The second did but does not pair with any Zigbee hub except either the MI or Aqara hub. It also does not appear in the list unless you live in mainland China as these are the Servers used. Neither the product description nor the product itself warn you of this.All instructions are in Chinese so I had to do a lot of searching to find this out. This product is unfit and should not be sold in the UK market.

So this is not plug and play for smartthings and you will have to log in to the ide section and setup a custom device handler but this is very simple and took a couple of minutes to have it in my smartthings app. I then had this as a better trigger than time for my light motion sensor and now when it is too dark, no matter the time of day, it will trigger my light if it senses motion and if it's bright then it won't. I have played around and I found that under 200 lux was a good trigger to turn on and over 250 lux to turn the light off, I did have the lux close together but when the lights came on at 199 lux it turned them off as the bulbs took it over the 200 so I now have a 50 lux limbo where it's neither too dark or too light but it works fine that way.Once you have the device handler set up, you can easily add more of these but Google the code as there are some newer ones that work better with more accurate lux readings
