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

[dewilmaniak]

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.

Cheers

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 ?

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

thanks

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

Current State node - attributes

Hi, I am breaking my head and probably overthinking. i am trying to achieve the following. Based on the state of a window blind (cover) I am trying to switch on or off a light. Cover <20% is off, >20% is on. But the cover is a z-wave device integrated in hass via the vera integration (on the role to migrate but other point). So the cover presents its self in hass like: [image] now I am trying to use the “current state node” to select what output to use and switch: [image] But obviously …

Help with Node-Red required for Covers position

Hi all, I’m only just starting to get into Node-Red after a long spell of using Automation within HA. I am attempting to set the position of a Cover (blind) to a specific open position and a specific time. I have generated the code in Developer Tools > Services as follows: entity_id: cover.staircase_blinds position: 40 but when i try to put that into NodeRed Edit JSON section in a Call Service node, it converts it to: entity_id: cover.staircase_blinds position: 40 then when i deploy and t…

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.
