Blue buttons send text to the Google Home Mini.

(will also be configured to talk to the other GH units in future...)

Letter buttons control devices directly...

'*' & '#' will be adjustment controls later...

Basic shopping list

The Circuit

The firmware

Current version of the firmware actually causes it to publish which button has been pressed. So NR can decide what to do with them. (Original firmware sent MQTT to the Google Home topic(s)...)

Problems

• Converting to pro-mini from uno
  • Less memory?... must optimize
  • NOPE! Pro-Mini has EXACTLY the same memory as the UNO
  • Bloody Hell! UIPEthernet library is fucking MASSIVE!
    • (Also: UIPEthernet contains silly & annoying warnings)

	Ethernet.h (W5100)	UIPEthernet.h (ENC28J60)
Data	1194	1867
Program	16664	24956

• Sadly, need UIPEthernet for the ENC28J60
  

• huh... more than one online at once causes some sort of looping in the broker connection... weird
  • Duh... client.connect("ClientName") needs a unique ClientName...

To be done

• Needs a reset button that's more accessible.
• Needs an OK indicator light.
