Node-red MQTT automation?

Third party integrations Node-RED
1

Hi there,

I have installed a zemismart blind cover, from home assistant it is all working… Open and close etc.

Now I would like to automate some stuff with this blind based on time, and there is the problem… I’m New to node red and have never used MQTT nodes, that’s what I need to control the blind right? I added the blind true zigbee2mqtt. See link:

But now the question, I do I make a time based trigger to set the"position" of the blind?

I understand that I need to publish true a topic etc, but I have no clue how.

Thx for the feedback in advanced

If you have the cover already in HA you can use the call-service node to set the cover position

if you just want to use mqtt something like this (untested)

@Kermit

Thx for the reply, when I’m home I will dive in to it.

From what I see you use a inject node to set the value for the position right? For the call service node, I only have a entity for the blind, not for “position” as far as I know.

“Edit: I see you select domain-cover, is that the way to talk for the position?”

Can I import you code, and start from there?

When I use mqtt I have to set the payload before the mqtt node? I was looking into the mqtt node but only find a topic setting.

Edit: I tried both of you’re flows… both are working proper! thank you!
