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.
