HomeWizard Energy device timout - how to find out which one it is?

In my logs, I see a few times a day:

Error fetching homewizard data: Timeout occurred while connecting to the HomeWizard Energy device

The problem is that I have a dozen of these devices, some Energy Sockets, 2 kWh meters, a water meter and a P1 dongle. I’m curious to find out which device it is, but there is no information like an IP address of MAC address in the error message.

Does anyone know of a way to figure out which device experienced the timeout? Then I can more specifically start looking into improving its wifi connection for example.
