Best hardware to control venetian bilnds with OH (tilt angle)?

Hello August.

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.

Good luck.
