I'd like to explain where we are in the grand scheme of things. Getting the rackinjector out the door took pretty much all of our R&D engineering for the last year or so. BUT... there's a reason for this, and it is related to the technology which is underpinning the web interface on that device. And which is related to our fairly near-term future as far as packetflux goes...
The architecture underneath the rackinjector control system is far more layered and abstracted than it would need to be to provide just the web interface. Every piece of data is abstracted into a generic data format inside the unit, and the system is designed in a way to greatly simplify the addition of additional features. The overriding idea is an on-site system which is able to gather up status from the entire site and also be able to control an entire site. To sort of give you a glimpse, in the rackinjector, there is a module for gathering up data from a NMEA GPS stream (GPS lock status, etc), a separate module for measuring the timing of the PPS pulses, a separate module for the analog digital controllers, another module to pull data from sitemonitor expansions (the expansion cards in the rackinjector are running the same underlying protocol as the sitemonitor expansion cards are today), and so on. Each of these modules pull data from their information source and makes it available in a generic manner to the system. For instance, the number of satellites in view is accessed in exactly the same way internally as a voltage reading. This abstraction allows me to add additional modules to pull data quickly - all I have to do is to create a chunk of code to pull data from say a solar charge controller or pull values via SNMP from a radio. The difficulty varies of course based on how hard it is to access the data, but it's a lot easier than writing an entire stack for each device. Today the rackinjector is running what we call internally the "DeviceManager" code on top of this. Generally what this is is a purpose-built web interface which is built on the underlying architecture. The web-interface actually pulls the data it needs from the underlying system using another generic chunk of code so it is relatively easy for us to add additional fields and support for additional devices. The "DeviceManager SNMP" module allows quick development of SNMP mibs again for specific purpose appliances. There's a few other tricks coming as well. Our intent with this code base is to build a set of specific-purpose appliances to pull data largely from one device or a couple of devices and provide it in a simplified manner to the user. For instance a Solar Charge controller monitor. Or a RackInjector controller. The key point here is that the DeviceManager codebase is designed largely to hide all of this from the end-user, while making it easy for us to build these products quickly. Now, back to the main point: This same flexible architecture permits us to also build various automated control systems on top of the same underlying architecture. If you replace the fixed-function devicemanager interface with a programmable, scriptable, flexible interface, all sorts of things start to happen. Including all of the items we're discussing in this thread. We already sell all of the physical interfaces needed to get a generator controller running - you can plug a unregulated power supply into a voltage input to get a rough idea of the AC voltage, or can get the DC voltage using another voltage input. You have contact closures in the form of another sitemonitor expansion module. And so on. What is missing is some sort of on-site automation, and that's where we've been heading with this entire architecture for about 2 years now. I don't know how quickly this is going to happen. The next 30 days I'm focused on 'finishing' the rackinjector - meaning shipping the cambium sync cards and the new 'either polarity' cards, and getting a new firmware out for it which has the "Devicemanager SNMP" code running in it. Once that is done we can re-focus on how to prioritize the future of this architecture.
