Hi there and thanks for sharing your project! I've tried to do a similar arrangement with a dht22 sensor and everything is working well untill step 4. I receive data from arduino that I can print on terminal. Then I have the json file downloaded, the docs table shared with the email and I can print ...

Do you think connecting the sensors to this board (https://www.cooking-hacks.com/hydroponi ... nics-board) and then to an Arduino mini and then to the RPi would work?
