Inconsistent behavior of the remote's power button

[AlexS]

So, I think the problem was caused by the combination of sub-optimal positioning of the remote (I adjusted it, to point to the unit), and my using the Devialet microfiber cloth to cover the remote (to protect it from dust), which I never remove. Surprising (or even ludicrous) as this may sound, I think this cloth may weaken the wifi signal. At some point, it was enough for me to slide it forward, to fully cover the front of the remote, for the problem to happen (but since I repositioned the remote, I can't recreate the cloth trick). Anyhow, the problem seems gone.
