mark_failed()

void esphome::Component::mark_failed ( )

virtual

Mark this component as failed.

Any future timeouts/intervals/setup/loop will no longer be called.

This might be useful if a component wants to indicate that a connection to its peripheral failed. For example, i2c based components can check if the remote device is responding and otherwise mark the component as failed. Eventually this will also enable smart status LEDs.

set_interval() [1/2]

void esphome::Component::set_interval ( const std::string &  name, uint32_t  interval, std::function< void()> &&  f  )

protected

Set an interval function with a unique name.

Empty name means no cancelling possible.

This will call f every interval ms. Can be cancelled via CancelInterval(). Similar to javascript's setInterval().

IMPORTANT: Do not rely on this having correct timing. This is only called from loop() and therefore can be significantly delay. If you need exact timing please use hardware timers.

Parameters

name	The identifier for this interval function.
interval	The interval in ms.
f	The function (or lambda) that should be called

protected

Set an retry function with a unique name.

Empty name means no cancelling possible.

This will call f. If f returns RetryResult::RETRY f is called again after initial_wait_time ms. f should return RetryResult::DONE if no repeat is required. The initial wait time will be increased by backoff_increase_factor for each iteration. Default is doubling the time between iterations Can be cancelled via cancel_retry().

IMPORTANT: Do not rely on this having correct timing. This is only called from loop() and therefore can be significantly delayed.

Parameters

name	The identifier for this retry function.
initial_wait_time	The time in ms before f is called again
max_attempts	The maximum number of retries
f	The function (or lambda) that should be called
backoff_increase_factor	time between retries is increased by this factor on every retry
