I have Tellstick with 433 and z-wave. But sometimes too long distanse between many z-wave units.
I thought that Homey could work as a repeater.
I can let Home use units from Tellstick and make flows, but use Telldus live as before. Telldus works really good in automating lights and so on.
I also have Google nest which make me able to switch light with talk.
I hope Homey can make contakt with all other which not can be controlled by Tellstick.
