Support for ClearGrass humidity/temerature sensor

[dedors]

There are 2 new versions of a sensor which also works in the Mi Home app and has e-ink:
One is the upgraded LCD version:

Manufacturer Name: Qingping Technology (Beijing) Co., Ltd.
Model Number: CGG1

Using the current node does work but only returns battery value.

somebody got it to work with noble: https://github.com/alexvenom/XiaomiCleargrassInkDislpay

Second one is one with a clock:

Can these be supported?

What is the model number for the e-ink version of temp/hum sensor?
And for the second one? (link is not working more)

Model number of the fist is CGG1. It Identifies as "ClearGrass Temp & RH" on bluetooth scan.

Model number of the second (square with time, humidity and temperature) is LYWSD02MMC. It identifies as "LYWSD02" on bluetooth scan.
On this one I also get only battery status.
Maybe some reference: http://www.techort.com/how-i-took-data-from-the-ble-thermometer-from-xiaomi-habr/

(Both can only be added on china server in Mi Home so far I think, which I can't login. That means with the second one, I also can't set the correct time.

The fist one reports a battery status of only "12", even on the display it shows full battery (battery symbol with 5 steps))

I have integrated the following code and it works:
https://github.com/alexvenom/XiaomiCleargrassInkDislpay/blob/master/XiaomiClearGrassInk.js

Here is my branch:
https://github.com/szappanyos/node-red-contrib-xiaomi-ble/tree/support-cleargrass-cgg1

I haven't made a PR because I don't think it is integrated correctly and I think it breaks some things. I think it doesn't work if you try to use more devices in parallel.

Hi @szappanyos, I couldn't make it works with clear glass version, only get battery 12 sometimes
Could you check code?

@caobach42 I have made a fix.
Also make sure that you are using the support-cleargrass-cgg1 branch.
