Home Assistant pyscript to mass-update device areas

update_device_areas.py

import homeassistant


@service
def update_device_areas():
    devreg = homeassistant.helpers.device_registry.async_get(hass)
    entreg = homeassistant.helpers.entity_registry.async_get(hass)
    areareg = homeassistant.helpers.area_registry.async_get(hass)

    area_ids = []
    for a in areareg.areas.items():
        id = a[0]
        entry = a[1]
        log.debug(f"Area: {entry.id} {entry.name}")
        area_ids.append(entry.id)

    for d in devreg.devices.items():
        id = d[0]
        entry = d[1]
        log.debug(f"Device: {entry.name} {entry.area_id}")

        for area_id in area_ids:
            if area_id in entry.name and entry.area_id == None:
                log.info(f"Will put device {entry.name} into area {area_id}")

                # Uncomment the line below when you're happy that the script will make the correct changes
                # devreg.async_update_device(device_id=id, area_id=area_id)

Thanks for your help. I do not see any log messages from the script in the config/homeassistant.log, even if i change the logging to warn in your script :/
