Newkiton

I bought a temperature senson on Amazon (https://www.amazon.com/Newkiton-NK-01B-Thermometer-Temperature-Compatible/dp/B07W53L4RD) I wanted to integrate it into a Graphana dashboard and to do so I needed to figure out how to pull the data from it

With that in mind, I reverse engineered the protocol. At the moment I know the basic on how to get the temperatire readings from the device and not much more.

I am not that familar with BLE but I know wireshark so I used that to reverse engineer it. The I just copied the protocol and came up with this

The device seems to store the data on a NVM with a simple address scheme. I presume it wraps around but I haven't run it for long enough just yet.

To use this, just instanciate a device and call the temperature method. The temperature is only updated every 10 minutes so call it more frequently will only return a cached version

from Newkiton import Newkiton
import time

sensor = Newkiton.Newkiton(deviceAddr="8e:f9:00:00:00:ed")
while True:
    print("Temp={}".format(sensor.temperature()))
    time.sleep(60*10)

ThermoBeacon

This is another similar device from Amazon which I also bought. I based this code from https://github.com/rnlgreen/thermobeacon

from ThermoBeacon import ThermoBeacon
import time

sensor = ThermoBeacon.ThermoBeacon(deviceAddr="8e:f9:00:00:00:ed")
while True:
    print("Temp={}".format(sensor.temperature()))
    time.sleep(60*10)

MiTemperature

This is another similar device from Amazon which I also bought. I based this code from https://github.com/JsBergbau/MiTemperature2 https://www.amazon.fr/gp/product/B082B4X4B2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
