Is it possible to send a text to a nextion display connected to a D1 mini with esphome on it?
I mean to use it as a “frontdoor message” e.g. when the mailman arrives a d I want to send an instant message (via node red e.g.) like “please put package in front of door”?
Or is it mot meant to work like this?
yes, you can do that. You would have to design the Nextion HMI to have a text field on screen, then via serial from the ESP8266 (D1 mini, etc.) you would send the proper command to the Nextion display with the text as the payload to be displayed.
Check out the Home Assistant Switch Plate (HASP) Project. While it doesn’t use ESPHome, the concepts are the same.
As it turns out, the HASP already has functionality to do exactly what @sender describes as an example automation. Check out the project page here, this might be pretty much read-to-go including a 3D printed enclosure and PCB design.
hi, thanks all for the quick reply. That example automation link (https://github.com/aderusha/HASwitchPlate/blob/f4a4d1570f12bc944d3adbde575159892282ff18/Home_Assistant/hasp-examples/plate01/hasp_plate01_p0_messagedisplay.yaml#L28-L49). Is that code meant to paste in an esphome config?
Assume I am a beginner in displays with esphome and an intermediate homeassistant user (at least I think I’m intermediate:-)).
What I am looking for is a “cut and paste” config for esphome on a D1 mini… I bought:
That code was for the HASP project (my baby, so I’m a little biased :D).
Understand 
.
I would really be greatfull for an esphome yaml starter
Do you mean for esphome generally, or just for nextion?
Both, esphome with nextion to send messages to it via homeassistant/node red 
Take a look at the examples I pointed to.
You kinda got to understand the nextion system too. There some good tutorials on YT.
Nick, thanks for responding. The thing is that if I understood it including examples I would not be asking for help here. The example are all “not half exactly” what I am looking for… I needs some help and guidance, not links to other places (with partial documentation).
Yeah I understand that, but otoh no one is simply going to just write it for you.
So you understand the nextion system, including creation of HMI files? That has to be understood, and this is not the nextion forum.
Cheers for this, didnt know these existed
Ok, I give up. And not easy. spent hours of reading. trying and youtubing. there is just not so much “usable” info available.
I have the display connected to a flashed D1 min. It lits up, but I am fully diffused by the “nextion editor”
Do no know how to create a view and connect to a text sensor (or whatever) from home assistant.
also I have never successfully been able to upload file via SD card to the nextion. it always says
baud: 9600
SD Card Update.....
No Find File
Oh why is everything so frikkin hard!
any ideas to have simple-usable-text-screen connected via D1 Mini and esphome to send messages to?
EDIT: some life after "file - tft file ouput- copy to SD and in nextion.
I have:

I have:
I shows the display on the nextion and I can press it (turns green)
But I see noting in home assistant:
It might have to do with “all other options from binary sensor” but I don’t get that well:
I have had problems trying to get ESP Home to work with the Nextion and to HA.
I ended up using a Wemos D1 and used this web site for reference.
And this one as well.
Cameron, can you share your esphome config then?
As I said it didn’t work.

What did you mean with this then? Sorry, don’t get me wrong but what did you mean with your post?
I did not use ESP Home for the Nextion I used the second web link and modded it to link with HA and Node red.
Ok, thank you for that.
My question in this topic is how to get this working with esphome and the builtin api etc.
