Many of these sensors come in at around 40€. That is quite pricy so I opted for the cheap chinese solution at around 13.5€ per piece. You just have to be patient: 4+ weeks delivery time.
Setup into Home Assistant was straight forward. Add the device to the Z-Wave network via the web interface, rename it to mydoor… but then… How does the device report ‘door open’? The binary sensor that showed up, did nothing.
After some fiddling and searching I found that the sensor.mydoor_access_control changes it’s state rather unspectacularly from 23 to 22. It’s so inconspicuous that I didn’t notice the change the first few times I kept looking for changes.
Perfect! there is something we can use to integrate it to Home Assistant for automation and other stuff. Luckily there are templates that allow us to turn this into a binary sensor which is more useful in automations.
Add this to your configuration.yml:
1 2 3 4 5 6 7 8 9 10 11 12 | binary_sensor: platform: template sensors: door1: device_class: opening friendly_name: 'Haustür' value_template: >- {%- if is_state("sensor.mydoor_access_control", "22") -%} True {%- else -%} False {%- endif -%} |
this can then be integrated into an automation like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | automation: alias: "coming home" hide_entity: False trigger: platform: state entity_id: binary_sensor.door1 from: 'off' to: 'on' condition: condition: sun after: sunset action: - service: homeassistant.turn_on entity_id: - switch.main_light |
that’s it. hope this helps.
