Very good project it's really incredible and will be a great product.
For 433mhz : all the CHACON and DIO module (not so expensive, and can make a lot of things)
For bluetooth/Wifi : Bluetooth lights and bulbs
Philips HUE seems to already be integrated, so it's ok
FIBARO zwave modules (same thing than Philips HUE, so it would be perfect)
LEGRAND ZIGBEE devices
LEGRAND ECO COMPTEUR 412000
Can't wait for your answer
