Node-Red: Open Cover a nudge or set_cover_position + x or -x

Hi Community,

I have a little challenge and yet to find a solution. I have blinds/Covers that not only open up or close, but also, if you open them up just a little (1-2%) in any position they will open up and let light in.

Now I would like to find a way to tell the cover to just move a bit (1 or 2%). Any suggestions?

I dont have a target position, I just wanted to move it from the current position 1% up or down to open or close the blinds.

Thanks already, my brain is frozen right now and I suppose it is probably easy for many of you.


I don’t have a cover to test this with but this is the basic idea. It will add 1 to the current position, I assume 100 is fully open, if not subtract 1

could you please show a screenshot from the current state and attributes from your cover under developer tools?

I understand you want to open or close in increments of 1 or 2 %? so, if it is currently sitting at 53%, open or close it to 55% or 51%, right?

Hey @Mikefila , how you doing :slight_smile: ?

How does that ()entity.attibutes.etc thing work? could you please elaborate or give some documentation?


Not bad when I am not making problems for myself, lol. I pulled it out of one of these 2 posts

I haven’t found one main page, if that’s what you were looking for. I find all bits and pieces like this for pushing a friendly name in to a notify template.
