| name: Aqara TRV E1 External Temperature Control | |
| description: > | |
| This automation allows the Aqara TRV E1 Smart Radiator Thermostat to use temperature readings from an external sensor rather than its internal sensor. Whenever the temperature sensor reports a new value, it is sent to the TRV for more accurate climate control. | |

I can't get this blueprint to work.
This bit of the blueprint
aqara_trv_number_entity: >-
{% set device_entities = device_entities(aqara_trv_device) %}
{{ expand(states['number'])
| selectattr('entity_id','in', device_entities)
| selectattr('entity_id', 'contains', external_temperature_input_name)

expects my device to have an entity like number.*external*
In the Zigbee2MQTT UI, I can see that my TRV exposes an external temperature input:
But if I go to the device’s page in Home Assistant, I can’t see any entities for the external temperature input.
How can I make that entity accessible?

Does this blueprint have safeguards in place in the event of an HA server restart? For example, by forcing it to restart when HA starts?
