Ecowitt: broken after disabling then re-adding

The problem

I needed to briefly take down my Ecowitt weather station (turns out a spider was blocking the rain sensor). And so as to not collect garbage data from the various sensors, I disabled the device in HA, assuming I would then be able to enable it afterward.

But after clearing the spider & cleaning things, I found the Ecowitt integration was no longer appearing in the list of active integrations, even if searched for in the active integrations view. So I then re-added the Ecowitt integration, which generated a new tokenized URL for my GW1200B to send metrics to.

I now have two Ecowitt devices. One has zero entities, and the other has the usual (for my setup) 27 entities. But none of those entities are receiving data from the Ecowitt gateway.

I might go to a forum for tips on working this out, but this situation seems like unexpected behavior with the Ecowitt integration. I could attempt deleting the ecowitt device that lacks any entities, but I'm not confident that will preserve the historical data HA has already collected from my weather station.

Diagnostics information

I've attempted to gather diagnostic data for the Ecowitt integration, and as my HA now has two, there are two opportunities for this data. However, both result in zero byte (empty) files downloaded from HA. When I turn off debug logging for Ecowitt, that produces a downloaded log file. The first time I tried this, it contains one stack trace attributed to Ecowitt, and is attached below.

I then tried this procedure again, restarting HA after enabling debug logging. This again resulted in two empty diagnostic data files. For this iteration of turning debug logging off, the resulting log file download contained zero mention of ecowitt.

Anything in the logs that might be useful for us?

The only stack trace I found mentioning ecowitt (also contained within the log file attached in the "Diagnostics information" section above):
