I plan to publish state of the switch from HA to the LCD Display. But the display always shows off even i turn on the pump.
Pls help
The config looks like this:
binary_sensor:
- platform: homeassistant
id: water_pump
entity_id: switch.water_pump
i2c:
sda: D2
scl: D1
display:
- platform: lcd_pcf8574
dimensions: 16x2
address: 0x27
update_interval: 1s
id: lcd
lambda: |-
it.printf("My State: %s", id(water_pump).state ? "on" : "off");

What do you see in the esphome log when switch.water_pump
goes to on?

nothing got updated in the esphome log when switch.water_pump

Well looks like i solve this by manually adding the ESPHOME node manually instead of auto discovery and added by HA.
That solved the prob. now everything works!
Thanks
