Here is a demo that developed based on the Rapid IoT.
I think you can develop your own project in a short time after read the design user guide
Attachments are :
Project introduction:
An automatic botanic garden can take care of your special plant (e.g. tropical plant);
The humidity, temperature, illumination intensity can be captured then send to your phone by BLE;
User can monitor if the environment is good for plant;
When the external pump and humidifier are added, user can water the plant/add the humidity remotely.
Any issue or not clear, feel free to leave your questions here!
I really like the block diagram- it shows the major parts of the project at a glance
