Indigo Domotics

Seen these?

Low cost ($A23) device with two user buttons, LED matrix, accelorometer, Compass and BLE!

More expensive than the RPi Zero W, but you can program with Python or block programming for the less talented (like me!!).

Originally intended for the education market, my mind's running wild with ideas (maybe this is the device for those automated sprinkler valves I've been dreaming of?/)

That's pretty cool. I may have to pop for one when they come to the states. Then it can sit in the drawer here and keep my rPi and Arduino company.

No need to wait, they are here in the US: https://www.adafruit.com/category/932
