I’m looking for a good, stable solution to control venetian blinds with OH.
These would be my requirements:
automatization via OH-rules (up/down, tilt angle (!) ), dependent on weather, time, etc.
manual override via physical switches (each blind get’s a switch)
stable and hassle-free everyday use
wireless or wired: both would be ok, as long as it works
I’m not too concerned about the software-side of my project. I’ve played around a bit with OH in combination with some zigbee and wifi-devices (lights and power outlets), which worked out pretty good.
For the hardware-side, I just don’t know where to begin. I’ve read a ton about different actuators for roller shutters and blinds (fibaro, shelly mostly) - and they all don’t seem to work flawlessly.
The (18) blinds will be integrated in a new house - so wired connections would be possible.
My electrician made me a good offer for a Bticino-System to control the blinds (and lights).
Anybody knows how good the control of venetian blinds works with the bticino-binding? Is it possible to control the tilit-angle of the blinds?
Thanks in advance,

Is it ‘just’ the blinds you want to control in your home, or are you having more work done?
Obviously, I would recommend the Velbus VMB2BLE as a two channel controller, per blind. (1 channel for tilt, the other for drop)
Equally, a 4 channel relay pack, running from an ESP01 via MQTT would work too.
An expansion of this concept.
Adding local buttons would be a challenge, but not impossible.
A 4 relay ESP01 board would probably use the RS232 method to control the relays, so in theory you’d have the ability to use the 2 GPIO pins to detect buttons.
As always, these are just my thoughts, I’m sure there are hundreds of other options.
With a ZWave based system, you can make a ZWave remote directly talk to the blind actuator rather than through OH … but frankly, I haven’t had the need a single time in 4 years.
I’m glad I saved my money on switches. Your efforts are better invested into getting OH more resilient.
