Hi everyone,
i am currently planning to implement a automatic shutter blind control
Just wanted to ask the community what is the experience so far?
Is it better/more comfortabel to go with NodeRed and use any of the blindcontroller “binding” or create rules within OH directly and play with different items states like lux, altitude…
Please share your suggestions.
Thank you in advance.
Personally I try to limit the number of systems being involved, therefore try to do most within openhab.
One general thing:
Be cautious with any blind automation that’s related to a door, that you will not lock out yourself
Hi @openhab_knx,
I am controlling my blinds on two sides of the house (east and west) by openhab.
This is completely based on rules (currently Rules DSL but I am planning to migrate it to JS or Python rules) and I am using the following values:
The blind automation is configurable with some parameters to adapt it to the seasonal needs:
I can post more details if you like.
Cheers
Jonathan
wow looks great, i am very interested in the details.
My plan is to additionally use the illuminance sensor outdoor instead of the cloud coverage by openweathermap.
Are you also able to “lock” single shutters? For example if you watch TV and would like to exclude the shutter in the living room(rest of the shutters should continue with the shading) until you activate the automatic again.
What is your “sync” time? In which time frame you are reacting changes (temp, cloud coverage azimut and elevation?). I am planning to use about 30min to avoid a “shutter loop” if there are many changes outside. (cloud and windy which affects the illuminance etc.)
Thank you in advance.
This is also my plan for the future - in the meantime I use the cloud coverage. But to be honest: most of the time I simply let the blinds down as soon as the sun comes around the house corner - no matter how bright the sun ist 
I have thought about that but haven’t implemented it yet.
The scripts runs as soon as my item for the sun azimuth changes. And these items will be updated every 15 minute by the astro binding.
And yes, I have switches and settings for the opening of the blinds but in most cases I use just the closing automatism.
This basic code is based on some other community member’s code which I adapted for my needs. I also had some thoughts of refactoring the code to make it more readable and reusable, but I simply had no time for this until now.

Hi Jonathan,
Thank you, so we are on the same way…
Have modified the same code as mentioned in this topic
