sensor availability not checked ?

[GH2user]

I have a max sensor based on the DSMR voltage sensor.
This is not available when HADailySensor is starting and thus gives an error.

Logger: custom_components.daily.sensor Source: custom_components/daily/sensor.py:156 integration: Daily Sensor ([documentation](https://github.com/jeroenterheerdt/HADailySensor), [issues](https://github.com/jeroenterheerdt/HADailySensor/issues)) First occurred: 16:00:21 (6 occurrences) Last logged: 16:00:27 unable to convert unavailable to float. Please check the source sensor (sensor.electricity_meter_voltage_phase_l1) is available.

Adding an availability template to each daily_sensor would prevent this.

what is an availability template?

[GH2user]

It checks for the availability of the sensor, refer https://www.home-assistant.io/integrations/template/
The section on "STATE BASED SENSOR CHANGING THE UNIT OF MEASUREMENT OF ANOTHER SENSOR" is the clearest I suppose.
Also a lot of comments on this concept on Tweakers.net (assume you are dutch) and the HA-forum.

code snippet (spacing and code tags are not really working here for some reason;
template:

• sensor:
  • name: "fan speed percentage"
    unique_id: "IDsensor_fan_speed_percentage"
    state_class: measurement
    unit_of_measurement: "%"
    icon: mdi:fan
    state: >
    {{ state_attr('fan.itho_wifi_nrg_21a4','percentage') }}
    availability: >-
    {{ states( 'fan.itho_wifi_nrg_ssss' ) not in [ 'unknown', 'unavailable'] }}

or availability: "{{ states('fan.itho_wifi_nrg_ssss') | is_number }}"

Right,but that's of course not how it works in python when writing an integration. But I think I get now what you're after.

Thanks a lot Jeroen, Will test it later on.

Mm, not really happy after the restart. You want me to make a new Issue?

Same for me...
