did you ever test the Insteon? I mean…was there any voltage you say that resembled 5v and a UART or I2C connection to the BBB?
No, and I’m unsure how to go about doing so. I have never pulled the connector off, and have no idea what the pinouts are.
Sorry, I’m not a Beaglebone hobbyist; I’m a Homebridge hobbyist trying to get Homebridge working on the Hub Pro now that Insteon has discontinued HomeKit support (and then went out of business).
Is there enough power for the other parts of the BBB to work?
Definitely. It was running flawlessly off the SD card, other than needing an occasional restart.
Are peripherals in use or in the way of taking on too much per pin and having the pins maxed out at a specific mA?
The peripheral is the network board, which is feeding power to the BB. So…no?
Where are the schematics or diagrams and literature on these devices attached to the BBB?
I don’t think schematics are available; The Hub Pro is (was; it’s discontinued, unsupported, and Insteon has closed down) a proprietary product. As for literature, there’s a user manual, but I don’t know how helpful it will be, apart from the Specifications at the end. http://cache.insteon.com/documentation/2243-222-en.pdf
