Hi everyone,
For my renovation project I’ve done some research in how to automate my lighting. As there will be a lot of IoT devices I want to be working with a wired system to ensure enough room for all the additional wireless devices in the end.
Secondary I would like a stand alone wired system that can operate even when Home Assistant is out for a few minutes to prevent interruptions.
Because of those reasons I ended up with DALI, which is commonly used for building lighting automation.
After comparing a lot of brands I ended up with Dali4Net from Lunatone. Because this module has 4 dali lines with up to 265 DALI devices. This was important as there will be 4 seperate zones in the building which should be individually controllable.
The Dali4Net comes standard with a Modbus TCP interface which could be integrated into Home Assistant which is great because it doesn’t need any converters in between.
The only concern I have for this at the moment is the scan_interval
because the Modbus interface is a local polling.
So because I will be using dimmable led lights in the whole building I would like to create dimmers controlled through Home Assistant (with rotary encoders, have a few on an esp8266 at the moment) to controll the DALI lights by sending updated dimming levels to the different lights.
My question:
Will I be able to dimm the lights fluently because of the scan_interval
? Is the light level only updated every other second? Or half a second when lowering the interval?
