M5 Atom Matrix

ESPHome
1

I’m using ESPHome for the first time. I’ve got the basics figured out, my M5 Atom Matrix is on Wifi, and I’ve got a basic config sort of working but the main use case I can’t figure out. I’ve got two pages to my display, page1 is green and page2 is red. All I want to do is be able to select the page to cycle between green and red. I get a drop down in HA for page1 and page2 but changing them does nothing but it does show in the ESPHome log. I’m pretty sure it’s something to do with my display or select logic but I’ve tried everything. At the end of it I just want a way to display a red matrix or a green matrix and will use it to show my alarm status.

  1. You have no action attached to your select. Changing it just changes it, nothing else. Something like (not tested):
select:
  - platform: template
    name: "Template select"
    optimistic: true
    options:
      - one
      - two
    initial_option: one
    on_value:
       then:
        - display.page.show: !lambda |-
            if (x == "one") {
              return id(page1);
            } else { 
              return id(page2);
            } }
  1. service: m5_matrix_change_page defines a service to be called from Home Assistant. If you want it to do something, in Home Assistant create a automation or script with a service call:
# Example Home Assistant Service Call
service: esphome.m5_matrix_change_page
data_template:
  page: 1

Thanks! I manage to get it to work by skipping the pages and just using it as a light that turns on and off, which is really all I need but I’ve saved your suggestion for further tinkering.
