Hello
i want to create display for some sensors from HA using nextion display and esp8266 d1 mini v2 and esphome api.
I wrote my yaml code by modifying:
GitHub - bruxy70/Home-Assistant-ESPHome-Weather-Station: Nextion display with ESP8266 microcontroller (Wemos D1 mini) showing Home Assistant temperature sensors and weather forecast
but i recive value “nan” from HA sensor. Accordin to my reserch that kind of value apear when esphome node wasn’t added to HA integrations but i did it and nothing heppends…
hire is my extra minimalistic yaml code for esphome node:
esphome:
name: nextion-display-1
platform: ESP8266
board: esp01_1m
# Enable logging
logger:
baud_rate: 0 # Disable UART logging (pins GPIO1/3 are used for Nextion communication)
level: VERBOSE
# Enable Home Assistant API
api:
password: "****" #passoword was set in HA configuration.yaml
ota:
password: "*****" #this pass was auto generated
wifi:
ssid: "****"
password: "*****"
fast_connect: true
manual_ip:
static_ip: 192.168.0.173
gateway: 192.168.0.1
subnet: 255.255.255.0
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Nextion-Display-1"
password: "M9ZCdnlzkfnP"
captive_portal:
uart:
rx_pin: GPIO3
tx_pin: GPIO1
baud_rate: 9600
sensor:
- platform: homeassistant # outside temperature
id: temp_outside
entity_id: sensor.a4c138360801_humidity #there was temp sensor but i try another one... i didn't change sensor ID
display:
- platform: nextion
id: myTempNexition
update_interval: 1s
lambda: |- #I try different way to display variable
it.set_component_value("tempoutside",id(temp_outside).state); #it's not working even nan value
it.set_component_text_printf("tempoutside","%f",id(temp_outside).state); #it's show nan walue
it.set_component_text_printf("text","text_testowy"); #it's show text_testowy on diplay corretly
and there is log form esphome node in VERBOSE mode:
