PCF8574 interrupt pin #2282

Open pantherale0 opened 1 year ago

pantherale0 commented 1 year ago

Describe the problem you have/What new integration you would like I have a PCF8575 that is currently used purely for inputs from momentary buttons, software polling seems extremely slow and doesn't pick up state changed very quickly. This FR is to request support for the interrupt pin of a PCF8575 to allow near instant updates on events.

Please describe your use case for this integration and alternatives you've tried: Improvement to existing integration, no alternatives available due to limited configuration options

Adding support for interrupts would open possibility to use pule counters.... Support for interrupts is very much needed (and overdue).
