Design goals:
- sit under Hubitat hub
- hold the hub in place without it getting hot
- compatible with USB-C chargers - DONE
- add a Status OK LED - DONE
- circuit to sense the Hub is powered down (just the red led) and remove power from the hub until mains power is back. This would allow the hub to be self starting.
- Zigbee Module
- to enable onboard power loss monitoring and graceful shutdown
- enable battery state reporting
Feedback on these goals is very welcome, we fully intend to try and keep costs down as much as possible, so expensive suggestions may not get added to the list.
Ps this is the Existing shutdown method - hopefully we can remove the guess work.
