core: Reolink sensors and cameras randomly and often go "Unavailable" for about 1min 15 seconds

The problem

I don’t know exactly when this started happening but it was sometime within the last 1-2 months and I can’t exactly nail down if it started with an update to the core or an update to the reolink integration (or randomly) but this issue came on suddenly and is now a consistent issue that I’d never come across before. Randomly, throughout the day, my Reolink cameras and their associated sensors within HA all go into an “Unavailable” state for approx 1 minute and 15 seconds before they return to their normal state…for camera feeds that normal state is “Idle” and for sensors that normal state is “On”, “Off”, “Clear”, etc. I don’t see a pattern to how often or when this happens…sometimes it’ll happen every few hours and other times it will happen every 5 minutes. It is however always for around a 1 minute and 15 seconds…sometimes a few seconds more and sometimes a few seconds less. In this “Unavailable” state, the camera video feeds are still visible via the HA Overview dashboard and my custom camera specific dashboards. The sensors however (ie “Person”, “Pet”, “Vehicle”, “Motion”, “Visitor” etc) do not work at all while “Unavailable”. All of my cameras are connected to a Reolink RLN16-410 NVR which itself is connected via ethernet to the same switch as the HA box and I’ve verified that these 1 min 15 sec outages are not seen when accessing the NVR-connected cameras via a local web-browser, via the native app, or via the NVR’s local UI…translation, there doesn’t seem to be anything wrong with the NVR itself or the cameras. Has anybody else come across this? I turned on dubug logging on the integration to see if anything unusual popped up and I do see what seems to be corresponding errors that read “error mapping response to channels”…see below for a sample of that.

Additional information

The timestamp on the error log entry "fetching reolink.CamNVR data" has the same exact time as the beginning of one of the 1 minute and 15 second outages, though in this particular case the outage was only 1 min 10 seconds.
