Light switch is unavailable if made from switch template

[OleksandrBerchenko]

The problem

After HA restart, a light switch made from a switch template remains unavailable until the switch changed its state. This bug is introduced in 0.117, earlier it worked as expected.

Environment

• Home Assistant Core release with the issue: 0.117.5
• Last working Home Assistant Core release (if known): 0.116
• Operating environment (OS/Container/Supervised/Core): Virtualenv on Raspberry Pi
• Integration causing this issue: Light Switch
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/light.switch/

Problem-relevant configuration.yaml

switch:
  - platform: template
    switches:
      readinglamp_wrapper:
        value_template: "{{ states.switch.readinglamp.state == 'on' }}"
        availability_template: "{{ states.switch.readinglamp != None and states.switch.readinglamp.state != 'unavailable' and states.binary_sensor.power.state == 'on' }}"
        turn_on:
          service: switch.turn_on
          entity_id: switch.readinglamp
        turn_off:
          service: switch.turn_off
          entity_id: switch.readinglamp

light:
  - platform: switch
    name: readinglamp
    entity_id: switch.readinglamp_wrapper

switch.readinglamp comes from Xiaomi Gateway (Aqara) UI integration.

Maybe a weird question (and probably a bit off-topic as well). But... euhm... why are you using a switch template and use the light switch to convert it into a light? Why not use a light template directly?

@frenck To have a clean code :) Please note, I have a lot of similar switch templates (which handle a power outage) and not of them are used for lights. Until this bug is fixed, I have already converted all of them into light templates.

Thanks!

I think this is the same issue as https://github.com/home-assistant/core/issues/43457

Same problem here, some lights are unavailable but the original switch is.

The same issue occurs for me when just turning a switch into a light using the Light Switch platform. In other words, this occurs even when not using switch templates, it seems to affect any kind of switch that is turned into a Light Switch. A restart of HA resets the light switches so that they are shown as available again.

[RolandvanOers]

Problem is still the same indeed, anything turned into a light switch is unavailable after 1 or 2 uses

Can those having problems post the template light configuration in YAML?

Also, the light entities that are used within the template light or light switch, which integration/component ultimately supports those light entities?
