I have two LC-13s that connected just fine, but the third is impossible to add.
I do a factory reset of the LC-13, and then try to add it.
The Homey app asks med to press the middle button on the LC-13, and this is immediately recognized in the app.
Then the app asks me to press the middle button once more, but this is never recognized. No matter how many times I press the middle button, the app asks med to press the middle button.
Any suggestions what can be wrong?
