States stop updating after a while.

Hi all,
I’ve been using konnected and HA for a few months. Everything works well for a day or two and then the states from one or more of my boards stop updating. The wifi is still connected but the states don’t change. A quick power cycle of the konnected board solves the issue.
Anyone else have this issue?
Is there a command I can send via the network that will restart the board? I could schedule it for once a day.

I'm having the same issue here. Will work fine for a couple hours then nothing changes. Will be watching.
