Are you using Hass.io?

The config validation when using Hass.io doesn't seem reliable.

I've never used Hass.io so I can't really help you better than this. You can try to search this forum and the home assistant forum for similar questions.

Have you read about the mysensors network?

You need to have basic knowledge of the different parts of a mysensors network before you start configuring the controller.

You should also read about the different gateway options.

If you know the different parts of the network you will more easily understand how to configure the controller.

This is on my todo list. I hope to get to it soon.

You need to feedback the state change to home assistant by sending the new state from the receive function after the calls to digitalWrite and saveState.

Please post your json persistence file.

Add the following line in the receive function eg after the call to digitalWrite.

send(msg.set(state));

You need to feedback and send the changed state to home assistant, after writing the new state to the pin, in the receive function. Otherwise home assistant thinks that the message to change state did not reach the node, and returns to the old state.

It should be compatible as 2.2.0 is not a breaking change, as far as I know.

Please edit your post and put the sketch within code blocks so it's readable.
