I have bought a bunch of Sensing Labs temperature/humidity sensors for research purposes.
According to the data sheet the devices should work with any public network, but there is no documentation of the required AppKey.
I have only found the DevEUI, which is printed on the device. The preconfigured AppEUI seems to be 70B3D580A0000000 for all devices, that is what I got from the OTAA join request on my gateway. Of course I cannot register the devices without knowing the secret AppKey.
I bought the devices from the ThingPark market, so they might be preconfigured for the Actility network.
Does anyone have an idea how to program new keys into the device or to read out the AppKey?
There is at least an I2C header on the PCB so there might be an EEPROM or MCU that can be accessed.
I already tried to contact Sensing Labs, but their contact form does not seem to work either
