Most ZHA devices will have an LQI sensor that is disabled by default. If you want to access the values in templates, you will need to enable those sensor entities.
I already have enabled the LQI sensor of the device, but I want to access the LQI values of the device’s neigbours, as they are shown on “Manage ZigBee device” dialog of the ZHA integration.
So the result must be a list with 1-n members, not only the 1 value from the device’s LQI sensor.
