Tuya Local - 1 device out of 5 identical devices causing problems

I am using Tuya Local to talk to a number of ‘smart plugs’ and 4 out of the 5 are working well. However the 5th one was working well but I now get:

As I say, the other 4 devices that were all set up at the same time have been working well for about 2 weeks. I note that the device that is causing these errors is also closest to the WiFi router so I’m discounting communication issues (at least for now).
Does the ‘custom integration author’ have any advice?

Just replying to bring this back up the ‘list’ of topics.
Can someone suggest how to either fix this issue or how else I might go abut getting assistance?
