@electrik said in Wake-up by interrupt doesn't work: If the delay is not of importance to you, you can also have the sensor request its state from the controller each time it wakes up. No special modifications are needed than. It's true. But the controller must switch its relay state without having ack received from the node. That's not what MySensors plugin for Vera does. But you gave me an idea to implement an additional relay buildin into the gateway which will work as a proxy for my real actuator. Thank you!

@nagelc thank you for directing me to the log parser. It helped me to understand that my issue caused by lack of INCLUSION_MODE messages that is easily solved by uncommenting MY_INCLUSION_MODE_FEATURE in my gateway sketch. The second part of the question stays valid. I realize that choosing the "right" controller is much more than choosing the controller that works good with MySensors. Anyway, I appreciate any personal experience on that.

@skywatch that helped! resolved, thank you!
