Thanks for writing this summary. I’m a bit confused what development is active for OS 2.1 compared to Pi and Bo. I need to read more.
While Pi and Bo are potentially less secure, they also offer the opportunity to add another security layer. I have a question about securing the open port used for 2.1 that I will ask in an appropriate thread.
I’m looking forward to see your work. Both GPM and GPH are used in drip. Drip valves are rated at GPM. Few home users would know the volume of water through their drip system, so I’ll be interested in how this works.
As a Vera (Home Automation) user I’ve seen what happens when too much functionality is pushed into firmware. At some point functionality needs to be pushed out to other devices. So the questions is, most simply, what is appropriate to implement in firmware, and what is should be run other other, hopefully extensible, devices.
What will likely happen is that all the program space is used up on incremental improvements that don’t provide a full solution.

Likely the runtime duration constraint is a legacy from mechanical timing. I had a career employee in a very good sprinkler company tell me that the rain sensor worked by interrupting the neutral wire on the valve circuit. We were talking about microprocessor control at the time. So a lot of these companies are still in 1970. They are not in a business that has been forced to change to the same extent of many industries.
It makes sense that Ray first made the core functionality consistent with the way systems are traditionally operated. It also makes sense to rethink what works best, while still maintaining a well controlled and consistent system.
From a system design perspective it debatable what functionality belongs in the firmware, and what logic should be in a separate processes: Such as a web server, “the cloud”, or a home automation system. While variable timings belongs in the firmware, many advanced functions perhaps belong on something like the Raspberry Pi web server.
