Template Cover with Endstops¶
The following is an example configuration for controlling covers (like window blinds etc) with ESPHome. This guide assumes that the cover is set up with two endstops at the top and the bottom. When these endstops are reached, the cover will automatically stop.
To protect the motors from spinning indefinitely (in case an endstop fails) the motors also have a maximum run time - after 3 minutes they will automatically turn off even if the endstop is not reached.
ESPHome uses Home Assistant’s cover architecture model which has two states: “OPEN” or “CLOSED”. We will map OPEN to “cover is at the top endstop” and CLOSE to “cover is at the bottom”.
switch:
# The switch that turns the UP direction on
- platform: gpio
pin: D1
id: up_pin
# Use interlocking to keep at most one of the two directions on
interlock: &interlock_group [up_pin, down_pin]
# If ESP reboots, do not attempt to restore switch state
restore_mode: always off
# The switch that turns the DOWN direction on
- platform: gpio
pin: D2
id: down_pin
interlock: *interlock_group
restore_mode: always off

cover:
- platform: endstop

open_action:
- switch.turn_on: up_pin
open_duration: 2min
open_endstop: top_endstop
close_action:
- switch.turn_on: down_pin
close_duration: 2min
close_endstop: bottom_endstop
stop_action:
- switch.turn_off: up_pin
- switch.turn_off: down_pin
max_duration: 3min
You can then optionally also add manual controls to the cover with three buttons: open, close, and stop.
