OPNsense says my TV tuner is offline but it's clearly not

[road hazard]

I have a Silicone Dust HDHomeRun TV tuner. It's currently at IP address 172.16.50.138. If I look at HDCP leases in the dashboard, it shows my tuner as active but offline (see attached picture).

I can ping it and watch TV with it so why does OPNsense think it's offline?

UPDATE: Never mind. I power cycled it and it's showing as online now. Guess if it hasn't talked to the OPNsense box in a while it's considered 'offline'.
