Is it possible to change code of espimatic in such a way that one can use bistabil Relays? Like this.
The contacts this Relays hold the switch state after them were operated.
So it needs only one short flash to switch.
Hence, it would save electricity.
And if one could use then one more Pin as a tracer, this would be to be used a good combination around then ESPimatic as a Multiway switching as traveler system . In connection with a wall push-button.
A problem would maybe be which the ESP puts by a new start the GPIO Pin briefly on high?
