Setting up the Offset Values for the Blake device

Select your target device and note down the "Device ID" (Eg: BOLTXXXXXXXX).
Now go to your Bolt cloud account and navigate to the API section (Left hand side). Copy the API key of your account.
Decide your offset value that you want to subtract from the reading for both Temperature and Humidity values

Eg: For reducing the value by 3.5 for Temperature/Humidity you will have to keep the offset value as "3.5" and for increasing the value by 3.5 for Temperature/Humidity you will have to keep the offset value as "-3.5".
Once you have all the 3 details: "Device ID", "API Key" and "Offset value". Proceed to the next step.
For setting the Temperature Offset update the below command:

https://cloud.boltiot.com/remote/{API_KEY}/serialWR?data=TC1{OFFSET_VALUE} &deviceName={DEVICE_ID}
For setting the Humidity Offset update the below command:

https://cloud.boltiot.com/remote/{API_KEY}/serialWR?data=HC1{OFFSET_VALUE} &deviceName={DEVICE_ID}
Go to the web browser and run these commands.
After completing the above steps, restart the device and check if the value is correctly shown on the device LCD.
