Custom routes issue

When installing HA natively on a RPI and if static routing is needed, then the best solution is this one:

Another solution I didn't test:

Remote control trick

Sometimes a remote control can send multiple button/click triggers even when a button is pushed once.

That's the case with the Tuya Zigbee3.0 Remote Control With 4 Key] that I just bought to trigger a Zigbee dry relay MHCOZY TYZG-001-RF (only used in Zigbee mode & cabled in NO - Normally opened). This dry relay simulates a push button to open a Garage door.

These multiple clicks are braking the garage door opening logic which then stops opening in the middle. In order to solve this, I used what we call in IT a mutex.

Here are the scripts to make this work properly:

MHCOZY ZG-001

Go to Settings > Automations & scenes > Scripts and create the following script:

alias: Pulse TUZG Relay (0.5s)
mode: single
sequence:
  - target:
      entity_id: light.mhcozy_tyzg_001_rf
    action: light.turn_on
  - delay:
      milliseconds: 500
  - target:
      entity_id: light.mhcozy_tyzg_001_rf
    action: light.turn_off

Tuya Zigbee3.0 Remote Control

Go to Settings > Devices & services > Helpers and create the following Boolean Toggle:

Name: garage_remote_control_lock
Entity ID: input_boolean.garage_remote_control_lock

Make sure it's set to Off (click on it when created to set its state).

Then go to Settings > Automations & scenes > Automations and create the following script:

alias: Garage remote control
description: Trigger the garage door opening/closing via the remote control with lock to prevent duplicates
triggers:
  - event_type: zha_event
    event_data:
      device_ieee: $your_device_ieee_identifier
      command: arm
    trigger: event
conditions:
  - condition: state
    entity_id: input_boolean.garage_remote_control_lock
    state: "off"
actions:
  - action: input_boolean.turn_on
    data: {}
    target:
      entity_id: input_boolean.garage_remote_control_lock
  - action: script.pulse_relay_0_5s
    data: {}
  - delay:
      seconds: 3
  - action: input_boolean.turn_off
    data: {}
    target:
      entity_id: input_boolean.garage_remote_control_lock
mode: single

To make sure the value is at OFF at HA startup (i.e. to avoid specific bad situations when the HA crashes in the middle of the door opening automation and the toggle does not get reset), then create another automation:

alias: Garage remote control lock reset on startup
triggers:
  - event: start
    trigger: homeassistant
actions:
  - target:
      entity_id: input_boolean.garage_remote_control_lock
    action: input_boolean.turn_off
    data: {}
mode: single
