I’m new to this community and therefore appologies if I missed something in the search, but the sheer content is a bit overwhelming and maybe I’m missing the right search terms.
I’m searching for some cheap and compact smart switches to control my roller shutters. I have the wires all in one central place and need to power the shutters from there. Size is a factor (as I have to fit 18 x 2 channel switches in the compartment). I had hoped something with din rail exists with 1HP per 2ch.
As the rest is not yet existing I’m open to all technologies as long as I can integrate them with OpenHAB
So far I’ve found
- Sonoff stuff which seems to be “flashable” (they have 2ch and din rail 4ch) but 15cm for 4ch is quite space intense
- Z-Wave switches 1 HP / channel - pretty expensive
- “HomeMatic Wired RS485 Rollladenaktor” - 4HP / 2ch
- HomeMatic HM-LC-Bl1-FM - not din rail but the most space efficient I’ve seen so far. But quite expensive for 18 shutters
The last option would be to build something myself on the base of some 230v relais + something connected to a Raspis GPIO pins.
Does anyone else have another thing I might have missed?
