I have been busy bulding a new ehome demonstrator. It's not from lego like the LegoEHomeDemonstrator it's again from wood like eHomeDemosntrator v1. It's a little smaller and has lots of wireless devices based on the Wemos D1 Mini running Micorpython.
I presented it at the Nova Maker Faire 2017 and also gave a talk on a Maker's perspective on home automation.
For more info take a look at my ehome page.
