. 2 Smart Tracker BBD100-A10
. 2 Smart Temperature & Humidity Sensor BBW200-A1
. 1 Smart LED Color Bulb BBL227-A1
As there is no binding for BeeWi I started with the beewibulb script from Stephanie Maks viewtopic.php?f=37&t=117729 with the update from Gerrit Hannaert and got that running.
Next I wanted to get the information from the BeeWi 'BBW200 - Smart Temperature & Humidity Sensor'
This script reads the actual temperature, humidity, battery status and the device information. The historical data is not handled yet.
Future step would be to create a rule in OpenHab using the knowledge gathered.
Some output of the script:
Code: Select all
pi@raspberrypi:~ $ sudo ./beewiclim.py
Correct usage is "[sudo] beewiclim.py <device address> <command> [hci device]"
<device address> in the format XX:XX:XX:XX:XX:XX
Commands: stat - Get status
Commands: val - Get values (temperature, humidity, battery)
Commands: raw - Get values (temperature, humidity, battery)
[hci device] i.e. hci1 in case of multiple devices

Busy on pulling the historical data (temperature & humidity), having some troebles translating the data into values.
And sorry for the language mistakes, English is not my native language
Cheers!
