Possible SW developments
One future concept in regards to SW might be about developing more sophisticated control loops for a fully automated system, adaptable for different kinds of plants.
One can also envision an ML algorithm of sorts, what would entail gathering, analyzing and processing long-term sensor data.
Your endeavor is incredible. This endeavor has given me a lot to learn. I'd want to distribute it to the Xnxubd vpn browser apk team so they can read it and apply something fresh to our ongoing efforts.
